CROSS REFERENCE TO RELATED PATENT APPLICATIONS 
     This application claims priority to Chinese Patent Application No. 201810871817.4, filed on 2 Aug. 2018 and entitled “Measurement Methods, Devices and Systems Based on Trusted High-Speed Encryption Card,” which is hereby incorporated by reference in its entirety. 
     TECHNICAL FIELD 
     The present disclosure relates to the field of trusted computing, and particularly, to measurement methods, devices, and systems based on a trusted high-speed encryption card. 
     BACKGROUND 
     Measurements are a technical means to protect the integrity of a platform and a system. At certain specific moments, a measurement is performed for a target to obtain certain information about the target (such as a hash value of a file), and values of these pieces of information are compared with standard values that are previously recorded, thereby determining whether the integrity of the target is compromised. 
     Currently, two types of trusted computing exists: two technical routes, namely, a Trusted Platform Control Module (TPCM) and a Trusted Platform Module (TPM) of the International TCG (Trusted Computing Group), and corresponding chain of trust construction methods are as follows. 
     For a TPM-based chain of trust construction, core elements of trusted computing are a chain of trust and a trusted root. A Trusted Platform Module (TPM) in the TCG specification is a hardware trusted root of a trusted computing platform, and TPM is a security chip that provides protected secure storage and cryptographic computing capabilities. The TPM is physically connected to a computing platform, and connected to a CPU via an external bus, e.g., directly solidified on a motherboard and connected via an LPC bus (which a full name as Low Pin count) on a PC platform. A definition of “trusted” given in the TCG specification is an entity always running for a specific target in a predictable way. A core mechanism of trusted computing is to build a trusted computing environment through a chain of trust mechanism. Whether a running entity is trusted or not is based on the credibility of a previous operating process of a system. Based on this type of trusted relationship, if the system starts from an initial trusted root, this type of trust can be maintained by passing on in every conversion of a platform computing environment, thereby establishing a chain of trust of a level verifying a level and a level trusting a level on a computing platform. Such computing environment is always trustable, and can be trusted by local users or remote entities, as shown in  FIG. 1 . Key technologies for trusted computing include several parts: a trusted measurement (as shown by a solid line in  FIG. 1 ), a trusted report (as shown by a dotted line in  FIG. 1 ), a trusted storage (as shown by a dashed line in  FIG. 1 ), and a trusted network connection (as shown by a two-dot chain line in  FIG. 1 ), etc. 
     For a construction of a TPCM-based chain of trust, basic functions of a Trusted Platform Module are implemented by a Trusted Platform Control Module (TPCM), and its functional composition is basically the same as that of the TPM. However, since a core measurement root CRTM of the TPM (with a full name as Core Root of Trust for Measurement) is located in BIOS (with a full name as Basic Input/Output System), and is not protected by the TPM, the TPCM therefore proposes a new trusted measurement root design, which solves a problem associated with a starting measurement point of a trusted measurement root, and changes orders of starting and measurement. Based thereon, a process of chain of trust measurement using such chip as a trusted root is established. This enables the chip to control startup of a whole system, I/O interface control and system configuration, etc., and embodies a control effect of the chip for the credibility of the system. During a process of operational control transfer of a computing platform, a trusted root TPCM determines whether the authenticity and integrity of a next-level execution code have been tampered with. If not, a system passes an operational control privilege to the next-level trusted execution code. The scope of credibility of the system is extended to the next level of functional code. Similarly, this type of system control privilege is continuously passed on. A process of establishing and transmitting a chain of trust can thus be implemented, and a system-wide trusted construction is finally realized. A complete delivery process of system trust begins with a trusted root, and an order of system control privilege is passed from a trusted platform control module to a trusted BIOS and then to a trusted operating system loader, from the trusted operating system loader to a trusted operating system, and then from a trusted operating system to a trusted application. 
     For an IMA (with a full name as Internal Measurement Approach) measurement method, at the moment when an operating system loads a program into a memory for measuring a program file, a measurement result is processed by a trusted computing chip TPM. In this way, a chain of trust from the TPM hardware integrity measurement system application program is completed. 
     In a process of integrity measurement of a platform and a system, when a cryptographic algorithm of a trusted high-speed encryption card is dynamically loaded, traditional TPM and TPCM cannot guarantee active measurements of the platform and the system, and static and dynamic loading measurements of firmware related to high-speed cryptographic operations at the same time during a device startup. 
     In a process of performing an integrity measurement by a trusted security chip in existing technologies, no effective solution has yet been proposed for a problem of failing to guarantee active measurements of a platform and a system, and static and dynamic loading measurements of firmware related to high-speed cryptographic operations at the same time during a device startup.

If the integrity of the one or more firmware in the device actively measured by the BIOS is corrupted, a system of the device is prohibited from being started up, or the system is controlled to enter into a non-secure mode. 
     It is easy to note that a BIOS can actively measure at least one firmware in a device when an integrity measurement result performed on the BIOS by a trusted security chip indicates that the integrity thereof is not corrupted, and a determination of whether to start a system of the device is made based on a measurement result. Moreover, a measurement of a cryptographic operational firmware can be completed based on a measurement key provided by the trusted security chip. Compared with the existing technologies, at least one firmware in a device can be actively measured, and a measurement of a cryptographic operation can be completed when an integrity measurement is performed, thus achieving the technical effects of guaranteeing active measurements and a loading measurement of the cryptographic operation at the time of device startup when the integrity measurement is performed by a trusted security chip. 
     Therefore, the solutions provided by the embodiments of the present disclosure solve the technical problems of failing to guarantee active measurements of a platform and a system, and loading measurements of cryptographic operations at the same time during a device startup in a process of performing an integrity measurement by a trusted security chip in the existing technologies.

Apparently, the described embodiments represent merely a part and not all of the embodiments of the present disclosure. All other embodiments obtained by one of ordinary skill in the art based on the embodiments of the present disclosure without making any creative effort shall fall within the scope of protection of the present disclosure. 
     It should be noted that terms “first”, “second” and the like in the specification and claims of the present disclosure and the accompanying drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that data so used may be interchanged whenever appropriate, so that the embodiments of the present disclosure described herein can be implemented in a sequence other than those illustrated or described herein. In addition, terms “including”, “containing”, and variations thereof are intended to cover a non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may also include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

     Trusted Platform Module (TPM/TPCM) can be a security chip that provides integrity and authenticity guarantees for evidence, and is typically physically bound to a computing platform. 
     Trusted Measurement: A practical method of trusted measurement is an integrity measurement. The integrity measurement can be to compare a hash value of a code calculated by a hash function with a stored hash value, to find out whether the code changes, and have a system to make a corresponding judgment according to a comparison result. 
     Trusted Static Measurement: Participate in establishing a chain of trust during a startup of a system, and evaluate the chain of trust no more after the startup of the system is completed, and during running of the system.

It should be noted that steps shown in a flowchart of the accompanying drawings may be executed in a computer system such as a set of computer executable instructions. Furthermore, although a logical order is shown in a flowchart, in some cases, steps shown or described may be performed in a different order than the one described therein. 
     The method embodiment provided in the first embodiment of the present disclosure can be performed in a mobile terminal, a computer terminal, etc.  FIG. 2  is a block diagram showing a hardware structure of a computer terminal (or a mobile device) for implementing a measurement method based on a trusted high-speed encryption card. As shown in  FIG. 2 , the computer terminal  20  (or the mobile device  20 ) may include one or more ( 202   a ,  202   b , . . . ,  202   n  as shown in the figure) processors  202  (the processor  202  may include, but is not limited to, a processing device such as a micro-processor MCU or a programmable logic device FPGA), a memory  204  used for storing data, and a transmission device  206  used for communication functions.

One skilled in the art can understand that the structure shown in  FIG. 2  is merely illustrative, and does not limit the structure of the above electronic device. For example, the computer terminal  20  may also include more or fewer components than those shown in  FIG. 2 , or may have a configuration different from that shown in  FIG. 2 . 
     It should be noted that one or more of the processors  202  and/or other data processing circuits may generally be referred to as “data processing circuits” herein. The data processing circuit may be embodied in whole or in part as software, hardware, firmware or any other combination. Moreover, the data processing circuit can be a single and separate processing module, or incorporated in whole or in part into any of the other components in the computer terminal  20  (or the mobile device). As involved in the embodiments of the present disclosure, the data processing circuit is used as a processor control (e.g., selection of a variable resistance terminal path connected to the interface). 
     The memory  204  can be used to store software programs and modules of application software, such as program instructions/data storage devices corresponding to the measurement method based on the trusted high-speed encryption card in the embodiments of the present disclosure. The processor  202  performs various functional applications and data processing by running software program(s) and module(s) stored in the memory  204 , i.e., to implement the measurement method based on a trusted high-speed encryption card as described above. The memory  204  can include high-speed random access memory, or can include a non-volatile memory, such as one or more magnetic storage devices, a flash memory, or other non-volatile solid state memory. In some examples, the memory  204  can further include storage devices remotely located relative to the processor(s)  202 . These storage devices can be connected to the computer terminal  20  over a network. Examples of such network include, but are not limited to, the Internet, an intranet, a local area network, a mobile communication network, and a combination thereof. 
     The memory  204  may include a form of processor-readable media such as a volatile memory, a random access memory (RAM) and/or a non-volatile memory, for example, a read-only memory (ROM) or a flash RAM. The memory  204  is an example of a processor-readable media. 
     The processor-readable media may include a volatile or non-volatile type, a removable or non-removable media, which may achieve storage of information using any method or technology.

It should be noted that  FIG. 2  is only an example of a specific embodiment, and is intended to show types of components that may be present in the aforementioned computer device (or the mobile device). 
     Optionally, the trusted high-speed encryption card in the present disclosure may be formed by a trusted TPM/TPCM module and a reconfigurable high-speed cryptographic operational module such as an FPGA. The trusted module can ensure the integrity of a platform and a system through low-speed operations, and guarantee the integrity of high-speed cryptographic dynamic loading and dynamic operation-related firmware. The high-speed cryptographic operational module completes secure high-speed cryptographic operations under an assurance of the integrity of the trusted module. 
     From measurement time points, measurements can include a static measurement and a dynamic measurement. A static measurement is involved in establishing a chain of trust during a startup of a system, and the chain of trust is no longer evaluated after the startup of the system is completed or during running of the system. A dynamic measurement can refer to a dynamic trusted measurement of a measurement target when any trusted measurement request is received. 
     From measured objects, measurements may include a platform system measurement and a cryptographic operation measurement. A platform system measurement may refer to security measurements related to a platform and a system when or after a device is started. Such measurements are completed by a trusted module. A cryptographic operation measurement may be referred to as a measurement related to a user cryptographic operation, which is cooperatively performed by a trusted module and a FPGA high-speed cryptographic algorithm. 
     In the above operating environment, the present disclosure provides a measurement method based on a trusted high-speed encryption card as shown in  FIG. 3 .  FIG. 3  is a flowchart of a measurement method based on a trusted high-speed encryption card according to the first embodiment of the present disclosure. As shown in  FIG. 3 , the method may include the following steps. 
     Step S 32 : A BIOS actively measures at least one firmware in a device if an integrity measurement made by a trusted security chip for the BIOS indicates that the integrity thereof is not corrupted. 
     Specifically, the trusted security chip may be a trusted TPM/TPCM module in a trusted high-speed encryption card as described above, and may perform a measurement of the integrity of a BIOS of an OEM (with a full name as Original Equipment Manufacturer) server manufacturer. 
     Optionally, the firmware may include at least one of: a trusted high-speed cryptographic algorithmic firmware, a peripheral storage device, a memory, and a hardware device. 
     Specifically, a building architecture of measurement of a chain of trust is proposed based on a trusted high-speed encryption card.  FIG. 4  shows a building architecture of measurement of a chain of trust based on a BIOS extension, which can modify a BIOS of an OEM server manufacturer, to enable the BIOS to actively measure all ROM (with a full name as Read-Only Memory) of peripherals and firmware of other hardware. 
     As shown in  FIG. 4 , a building architecture of a measurement of a chain of trust based on a BIOS extension mainly shows a delivery of a static measurement of the chain of trust, and may specifically include an integrity measurement of the BIOS performed by a trusted TPM/TCM module, an integrity measurement of a cryptographic operational firmware and other device firmware(s) of the trusted high-speed encryption card performed by the BIOS, an integrity measurement of a Boot Loader performed by the BIOS, and an integrity measurement of system kernel(s) performed by the Boot Loader. Data interactions between a trusted TPM/TPCN module and a FPGA high-speed cryptographic operational module may include a trusted storage and a trusted report. The trusted storage may be to send sensitive information associated with high-speed cryptographic operation(s) such as a hash value of the high-speed cryptographic operational firmware, and a measurement root for the cryptographic operation(s), etc., from a FPGA high-speed cryptographic operational module to the trusted TPM/TPCM module for storing in a PCR (with a full name as Program Control Register) value of the trusted TPM/TPCM module to obtain protection from the trusted module. The trusted report may be the trusted TPM/TPCM module to perform a hash calculation on a measurement of firmware(s) associated with high-speed cryptographic operation(s), and after obtaining a hash comparison result, to report thereof to trusted firmware(s) of a FPGA high-speed cryptographic operational module that is/are associated with the high-speed cryptographic operation(s). 
     It should be noted that, in order to implement a measurement method based on a trusted high-speed encryption card, a trusted security chip manufacturer or a trusted security chip user can be assumed to have placed a public key PK (RPM) of a platform measurement root in a CPU white list mechanism of a device host, and stored a private key SK (RPM) in a trusted security chip, which can specifically be implemented using Intel SGX technology. 
     Step S 34 : When the integrity of one or more firmware in the device actively measured by the BIOS is not corrupted, the one or more firmware is loaded. 
     Step S 36 : When the integrity of one or more firmware in the device actively measured by the BIOS is corrupted, a system of the device is prohibited from being started up, or the system is controlled to enter into a non-secure mode. 
     In an optional solution, in order to implement an integrity measurement of a device, an integrity measurement of a BIOS may be performed by a trusted security chip during a startup process of the device. When a result of the integrity measurement of the BIOS indicates that the integrity thereof is not corrupted, a firmware associated with a trusted high-speed cryptographic operation, such as the integrity of a cryptographic algorithm, can be actively measured by the BIOS, and the integrity of a ROM of a hardware peripheral and its firmware can also be actively measured, to determine whether a firmware integrity of the firmware associated with the trusted high-speed cryptographic operation and other hardware devices is corrupted. If no corruption exists, the firmware associated with the trusted high-speed cryptographic operation can be loaded, or firmware boot peripherals of the other hardware devices can be loaded. If a corruption exists, a system of the device is prevented from being started, or the system is started as a non-secure mode, to ensure the security of a device startup. 
     For example, for the building architecture of the chain of trust as shown in  FIG. 4 , a static measurement starting method of a corresponding trusted high-speed encryption card is shown in  FIG. 5 . Such method may include the following steps. 
     Step S 51 : A trusted high-speed encryption card is powered on. 
     Step S 52 : The integrity of a BIOS is measured. 
     Optionally, a measurement of the integrity of the BIOS can be completed using a platform measurement root of the trusted high-speed encryption card and public and private keys of platform measurement root keys. 
     Step S 53 : The integrity of the BIOS is determined. 
     Optionally, if the integrity of the BIOS is not corrupted, step S 54  and step S 58  can be performed. Otherwise step S 513  is performed. 
     Step S 54 : The integrity of a firmware associated with a high-speed cryptographic operation related is measured, and the integrity of ROM and hardware firmware of other peripheral(s) is measured. 
     Optionally, the BIOS can proactively measure the integrity of a firmware associated with a trusted high-speed cryptographic operation, as well as the integrity of a ROM of a hardware peripheral and its firmware. 
     Step S 55 : A determination is made as to whether the integrity of the firmware associated with the high-speed cryptographic operation and the firmware of other hardware devices is corrupted. 
     Optionally, if no corruption exists, step S 56  and step S 57  may be performed. Otherwise step S 513  is performed. 
     Step S 56 : A high-speed cryptographic operational module loads the firmware associated with the cryptographic operation. 
     Optionally, in response to determining that the integrity of the firmware associated with the high-speed cryptographic operation is not corrupted, the firmware associated with the high-speed cryptographic operation is loaded, and step S 58  is performed. 
     Step S 57 : The hardware peripheral(s) is/are loaded and started. 
     Optionally, in response to determining that the firmware integrity of the other hardware devices is not corrupted, the firmware boot peripherals of the other hardware devices are loaded, and step S 58  is performed. 
     Step S 58 : The BIOS measures the integrity of a Boot Loader. 
     Step S 59 : The integrity of the Boot Loader is determined. 
     Optionally, if the integrity of the Boot Loader is not corrupted, step S 510  may be performed. Otherwise step S 513  is performed. 
     Step S 510 : The Boot Loader measures the integrity of system kernel(s). 
     Step S 511 : The integrity of the system kernel(s) is determined. 
     Optionally, if the integrity of the system kernel(s) is not corrupted, step S 512  may be performed. Otherwise step S 513  is performed. 
     Step S 512 : A system is safely booted into a secure mode. 
     Optionally, after the trusted high-speed encryption card is started, the integrity of the BIOS, the integrity of the firmware associated with the high-speed cryptographic operation and the firmware of the other hardware devices, the integrity of the Boot Loader, and the integrity of the system kernel(s) can be sequentially measured. The device can be determined to be trustable only after determining that the integrity of all these measured objects is not corrupted, so that the system can be controlled to be safely booted and enter the secure mode. 
     Step S 513 : The system is prohibited from being started up, or is started to enter a non-secure mode. 
     Optionally, after the trusted high-speed encryption card is started, the integrity of the BIOS, the integrity of the firmware associated with the high-speed cryptographic operation and the firmware of the other hardware devices, the integrity of the Boot Loader, and the integrity of the system kernel(s) can be sequentially measured. The device is determined to be not trustable as long as the integrity of any one of the measured objects is determined to be corrupted. Therefore, the system can be controlled to be prohibited from being started up, or the system can be control to be started and entered into a non-secure mode. 
     In the method provided by the foregoing first embodiment of the present disclosure, when an integrity measurement of a BIOS performed by a trusted security chip indicates that the integrity of the BIOS is not corrupted, the BIOS may actively measure at least one firmware in a device. When the integrity of one or more firmware in the device measured by the BIOS is not corrupted, the one or more firmware may be loaded. When the integrity of one or more firmware in the device measured by the BIOS is corrupted, a system of the device may be forbidden from being started up, or the system may be controlled to enter into a non-secure mode. 
     It is easy to note that a BIOS can actively measure at least one firmware in a device when an integrity measurement result performed by a trusted security chip for the BIOS indicates that the integrity thereof is not corrupted, and a determination of whether to start a system of the device is made based on a measurement result. Moreover, a measurement of a cryptographic operational firmware can be completed based on a measurement key provided by the trusted security chip. Compared with the existing technologies, at least one firmware in a device can be actively measured, and a measurement of a cryptographic operation can be completed when an integrity measurement is performed, thus achieving the technical effects of guaranteeing active measurements and a loading measurement of the cryptographic operation at the time of device startup when the integrity measurement is performed by a trusted security chip. 
     Therefore, the solution of the foregoing first embodiment provided by the present disclosure solves the technical problems of failing to guarantee active measurements of a platform and a system, and loading measurements of cryptographic operations at the same time during a device startup in a process of performing an integrity measurement for a trusted security chip in the existing technologies. 
     In the foregoing embodiments of the present disclosure, before the BIOS actively measures at least one firmware in the device at step S 32 , the method may further include the following steps. 
     Step S 38 : A trusted high-speed encryption card is powered on and started. 
     Step S 310 : A platform measurement root of the trusted high-speed encryption card is obtained. 
     Specifically, the platform measurement root may include measurement code(s) for performing integrity measurement(s) on the device. The platform measurement root may be loaded into a memory space of the device when the device is started at the first time, and loaded from the memory to the CPU of the device. It should be noted that, in order to ensure the accuracy of the platform measurement root that is obtained, the trusted high-speed encryption card can encrypt the platform measurement root to obtain a trusted measurement root, load the trusted measurement root into the memory of the motherboard, and then load the trusted measurement root is loaded from the memory into the CPU. 
     Step S 312 : A trusted security chip uses the platform measurement root and a key to perform an integrity measurement for the BIOS. 
     Optionally, a host processor stores a public key of a key pair, and the public key and a private key that encrypts the measurement root together form a pair of asymmetrical measurement keys. 
     In an optional solution, the host processor decrypts the trusted measurement root using the public key to obtain a measurement root. The measurement root includes a measurement code. The measurement code is executed to obtain a measurement result of the BIOS. The measurement result is then encrypted using the public key to obtain a processing result. The host processor sends the obtained processing result to the security chip. The security chip decrypts the encrypted measurement result using the private key (i.e., the private key that encrypts the measurement root), and the measurement result can thereby be obtained. When the system is started for the first time, the measurement result can be hashed to obtain a hash value, which is stored in a PCR of the trusted chip as a measurement reference value. When the system is started again, a hash value of a measurement result is compared with the measurement reference value. If the hash value of the measurement result is the same as the measurement reference value, a determination is made that the BIOS is complete, i.e., the integrity of the BIOS is not corrupted. If the hash value of the measurement result is different from the measurement reference value, a determination is made that the BIOS is incomplete, i.e., the integrity of the BIOS is corrupted, and so a platform and a system are considered to have destructive attacks. 
     It should be noted that the integrity of at least one firmware in a device can also be measured using the above method. 
     In the above embodiments of the present disclosure, when an integrity measurement of the BIOS indicates that the integrity is corrupted, the system of the device is forbidden from booting, or the system is controlled to enter into a non-secure mode. 
     In an optional solution, the integrity of a BIOS is measured during a startup of a device. If the integrity of the BIOS is compromised, a determination can be made that the BIOS is incomplete and the device is not trustable. A system of the device is forbidden from booting, or the system is controlled to enter into a non-secure mode, to ensure the security of the startup of the device. 
     In the above embodiments of the present disclosure, after loading one or more firmware at step S 34 , the method may further include the following steps. 
     Step S 314 : The BIOS measures the integrity of a Boot Loader. 
     Specifically, the Boot Loader can be a program that runs before a system kernel or an application program runs. Using such program, a hardware device can be initiated, and a map of a memory space can be established, thereby bringing a hardware and software environment of the system to a suitable state, in order to prepare a correct environment for involving system kernels at the end. 
     In an alternative solution, the integrity of the Boot Loader can be measured using the method that measures the integrity of the BIOS as described above. 
     Step S 316 : The Boot Loader is triggered to measure the integrity of a system kernel of the device when the integrity of the Boot Loader measured by the BIOS is not corrupted. 
     In an alternative solution, the integrity of the system kernel can be measured using the method that measures the integrity of the BIOS as described above. 
     Step S 318 : When the integrity of the Boot Loader measured by the BIOS is corrupted, the system of the device is prohibited from booting, or the system is controlled to enter into a non-secure mode. 
     In an optional solution, during the startup of the device, after the firmware associated with the trusted high-speed cryptographic operation is loaded or the firmware booting peripherals of the other hardware devices is loaded, the integrity of the Boot Loader can be measured by the BIOS. If the integrity of the Boot Loader is not corrupted, the Boot Loader can be determined to be complete, and thereby the Boot Loader is executed. The integrity of the system kernel(s) of the device is measured by the Boot Loader. In response to determining that the integrity of the Boot Loader is corrupted, the Boot Loader can be determined to be incomplete, and the device is not trustable. Thus, the system of the device can be forbidden from being started, or the system is controlled to enter a non-secure mode, to ensure the security of the startup of the device. 
     It should be noted that the firmware associated with the trusted high-speed cryptographic operation and the integrity of the ROM of the hardware peripherals and the firmware thereof can be actively measured by the BIOS, when the BIOS is determined to be complete and the device is trusted. Furthermore, the integrity of the Boot Loader is measured by the BIOS. 
     In the foregoing embodiments of the present disclosure, after the Boot Loader is triggered to measure the system kernel of the device at step S 316 , the method may further include the following steps. 
     Step S 320 : A system of the device is securely started, and/or the system is controlled to enter into a secure mode when the integrity of the system kernel measured by the Boot Loader is not corrupted. 
     Step S 322 : When the integrity of the system kernel measured by the Boot Loader is corrupted, the system of the device is prohibited from being started, or the system is controlled to enter into a non-secure mode. 
     In an optional solution, the integrity of the system kernel of the device can be measured by the Boot Loader in response to determining that the integrity of the Boot Loader is not corrupted. If the integrity of the system kernel is determined to be not corrupted, the system kernel can be determined to be complete, and the device is trustable. The device can be controlled to start up the system safely, and control the system to enter a secure mode. If determining that the integrity of the system kernel is corrupted, the system kernel can be determined to be incomplete, and the device is not trustable. The system of the device can be prohibited from being started, or the system is started to enter into a non-secure mode, to ensure the security of the startup of the device. 
     It should be noted that the foregoing method embodiments are all expressed as a series of action combinations for the sake of description. One skilled in the art should understand that the present disclosure is not limited by the described sequences of actions, because certain steps may be performed in other sequences or concurrently in accordance with the present disclosure. Furthermore, one skilled in the art should also understand that the embodiments described in the specification all belong to exemplary embodiments, and actions and modules that are involved may not be necessarily required by the present disclosure. 
     Through the description of the above embodiments, one skilled in the art can clearly understand that the methods according to the foregoing embodiments can be implemented using software plus a necessary general hardware platform, and apparently can also be implemented by hardware. In many cases, the former is a better implementation. Based on such understanding, the essence of the technical solutions of the present disclosure or the parts that contribute to the existing technologies may be embodied in a form of a software product. Such computer software product is stored in a storage media (such as a ROM/RAM, a disk, an optical disk), and includes a number of instructions for causing a terminal device (which may be a mobile phone, a computer, a server, or a network device, etc.) to perform the methods described in various embodiments of the present disclosure. 
     Second Embodiment 
     According to the embodiments of the present disclosure, an embodiment of a measurement method based on a trusted high-speed encryption card is also provided. It should be noted that steps shown in a flowchart of the accompanying drawings may be executed in a computer such as a set of computer executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps may be performed in a different order than the ones shown or described therein. 
     In the above operating environment, the present disclosure provides a measurement method based on a trusted high-speed encryption card as shown in  FIG. 6 . 
     Specifically, the trusted high-speed encryption card may be the same as the trusted high-speed encryption card in the first embodiment, and details thereof are not repeatedly described herein. 
       FIG. 6  is a flow chart of a measurement method based on a trusted high-speed encryption card according to the second embodiment of the present disclosure. As shown in  FIG. 6 , the method may include the following steps. 
     Step S 62 : A BIOS actively measures the integrity of an option memory firmware of a trusted high-speed encryption card in a device when an integrity measurement of the BIOS performed by a trusted security chip indicates that the integrity thereof is not corrupted. 
     Specifically, the trusted security chip may be a trusted TPM/TPCM module in the trusted high-speed encryption card. The integrity of a BIOS of an OEM (with a full name as Original Equipment Manufacturer) server manufacturer can be measured. The above option memory may be Oprom (Option ROM) of the trusted high-speed encryption card. 
     Step S 64 : The option memory firmware of the trusted high-speed encryption card is triggered to measure the integrity of one or more firmware in the device when the integrity of the option memory firmware of the trusted high-speed encryption card that is actively measured by the BIOS is not corrupted. 
     When the integrity of one or more firmware is not corrupted, the one or more firmware are loaded. Otherwise a system of the device is forbidden from being started, or the system is controlled to enter into a non-secure mode. 
     Optionally, the firmware may include at least one of: a trusted high-speed cryptographic algorithmic firmware, a peripheral storage device, a memory, and a hardware device. 
     Specifically, based on the trusted high-speed encryption card, a building architecture of a chain of trust is also proposed.  FIG. 7  shows a building architecture of a measurement of a chain of trust based on an Oprom extension, which can modify a BIOS of an OEM server manufacturer, to enable the BIOS to measure the integrity of Oprom of a trusted high-speed encryption card. The trusted high-speed Oprom then measures ROM and other firmware of all peripherals. 
     As shown in  FIG. 7 , a building architecture of a measurement of a chain of trust based on an Oprom extension mainly shows a delivery of a static measurement of the chain of trust, and may specifically include an integrity measurement of a BIOS performed by a trusted TPM/TCM module, an integrity measurement of an Oprom of a trusted high-speed encryption card performed by the BIOS, a cryptographic operational firmware and other device firmware(s) of the trusted high-speed encryption card performed by the Oprom of the trusted high-speed encryption card, an integrity measurement of a Boot Loader performed by the Oprom of the trusted high-speed encryption card, and an integrity measurement of system kernel(s) performed by the Boot Loader. Data interactions between a trusted TPM/TPCN module and a FPGA high-speed cryptographic operational module may include a trusted storage and a trusted report. The trusted storage may be to send sensitive information associated with high-speed cryptographic operation(s) such as a hash value of the high-speed cryptographic operational firmware, and a measurement root for the cryptographic operation(s), etc., from a FPGA high-speed cryptographic operational module to the trusted TPM/TPCM module for storing in a PCR (with a full name as Program Control Register) value of the trusted TPM/TPCM module to obtain protection from the trusted module. The trusted report may be the trusted TPM/TPCM module to perform a hash calculation on a measurement of firmware(s) associated with high-speed cryptographic operation(s), and after obtaining a hash comparison result, to report thereof to trusted firmware(s) of a FPGA high-speed cryptographic operational module that is/are associated with the high-speed cryptographic operation(s). 
     It should be noted that, in order to implement a measurement method based on a trusted high-speed encryption card, a trusted security chip manufacturer or a trusted security chip user can be assumed to have placed a public key PK (RPM) of a platform measurement root in a CPU white list mechanism of a device host, and stored a private key SK (RPM) in a trusted security chip, which can specifically be implemented using Intel SGX technology. 
     In an optional solution, in order to implement an integrity measurement of a device, an integrity measurement of a BIOS may be performed by a trusted security chip during a startup process of the device. When a result of the integrity measurement of the BIOS indicates that the integrity thereof is not corrupted, the integrity of an Oprom of a trusted high-speed encryption card in a device can be actively measured by the BIOS. If the integrity of the Oprom of the trusted high-speed encryption card is not corrupted, a firmware associated with a trusted high-speed cryptographic operation, such as the integrity of a cryptographic algorithm, can be measured by the Oprom of the trusted high-speed encryption card, and the integrity of a ROM of a hardware peripheral and its firmware can also be actively measured, to determine whether a firmware integrity of the firmware associated with the trusted high-speed cryptographic operation and other hardware devices is corrupted. If no corruption exists, the firmware associated with the trusted high-speed cryptographic operation can be loaded, or firmware boot peripherals of the other hardware devices can be loaded. If a corruption exists, a system of the device is prevented from being started, or the system is started as a non-secure mode, to ensure the security of a device startup. 
     For example, for the building architecture of the chain of trust as shown in  FIG. 7 , a static measurement starting method of a corresponding trusted high-speed encryption card is shown in  FIG. 8 . Such method may include the following steps. 
     Step S 81 : A trusted high-speed encryption card is powered on. 
     Step S 82 : The integrity of a BIOS is measured. 
     Optionally, a measurement of the integrity of the BIOS can be completed using a platform measurement root of the trusted high-speed encryption card and public and private keys of platform measurement root keys. 
     Step S 83 : The integrity of the BIOS is determined. 
     Optionally, if the integrity of the BIOS is not corrupted, step S 84  and step S 810  can be performed. Otherwise step S 815  is performed. 
     Step S 84 : The integrity of Oprom of the trusted high-speed encryption card is measured. 
     Step S 85 : The integrity of Oprom of the trusted high-speed encryption card is determined. 
     Optionally, if the integrity of Oprom of the trusted high-speed encryption card is not corrupted, step S 86  and step S 810  may be performed. Otherwise step S 815  is performed. 
     Step S 86 : The integrity of a firmware associated with a high-speed cryptographic operation is measured, and the integrity of other peripheral ROM and hardware firmware is measured. 
     Optionally, Oprom of the trusted high-speed encryption card can actively measure the integrity of the firmware associated with the trusted high-speed cryptographic operation, as well as the integrity of ROM of hardware peripherals and respective firmware. 
     Step S 87 : A determination is made as to whether the firmware integrity of the firmware associated with the high-speed cryptographic operation and other hardware devices is corrupted. 
     Optionally, if no corruption exists, step S 88  and step S 89  may be performed. Otherwise step S 815  is performed. 
     Step S 88 : A high-speed cryptographic operational module loads the firmware associated with the cryptographic operation. 
     Optionally, if determining that the integrity of the firmware of the high-speed cryptographic operation is not corrupted, the firmware associated with the high-speed cryptographic operation is loaded, and step S 810  is performed. 
     Step S 89 : Loading of hardware peripheral(s) is started. 
     Optionally, if determining that the firmware integrity of the other hardware devices is not corrupted, firmware boot peripherals of the other hardware devices are loaded, and step S 810  is performed. 
     Step S 810 : Oprom of the trusted high-speed encryption card measures the integrity of a Boot Loader. 
     Step S 811 : The integrity of the Boot Loader is determined. 
     Optionally, if the integrity of the Boot Loader is not corrupted, step S 812  may be performed, otherwise step S 815  is performed. 
     Step S 812 : The Boot Loader measures the integrity of system kernel(s). 
     Step S 813 : The integrity of the system kernel(s) is determined. 
     Optionally, if the integrity of the system kernel(s) is not corrupted, step S 814  may be performed. Otherwise step S 815  is performed. 
     Step S 814 : A system is booted safely into a secure mode. 
     Optionally, after a trusted high-speed encryption card is powered on, the integrity of a BIOS, the integrity of Oprom of the trusted high-speed encryption card, the firmware integrity of a firmware associated with a high-speed password operation and other hardware devices, and the integrity of a Boot Loader, and the integrity of a system kernel may be sequentially measured. Only when it the integrity of all these measured objects is not corrupted can a device be trusted, so that a system can be booted safely and enter into a secure mode. 
     Step S 815 : The system is prohibited from being started, or is started to enter into a non-secure mode. 
     Optionally, after a trusted high-speed encryption card is powered on, the integrity of a BIOS, the integrity of Oprom of the trusted high-speed encryption card, the firmware integrity of a firmware associated with a high-speed password operation and other hardware devices, and the integrity of a Boot Loader, and the integrity of a system kernel may be sequentially measured. As long as the integrity of any of the measured objects is determined to be corrupted, a determination can be made that the device is not trustable. Therefore, a system can be prevented from being started, or the system can be controlled to start and enter into a non-secure mode. 
     In the method provided in the second embodiment of the present disclosure, a BIOS can actively measure the integrity of an option memory firmware of a trusted high-speed encryption card in a device when an integrity measurement result of the BIOS performed by the trusted security chip indicates that the integrity thereof is not corrupted. When the integrity of the option memory firmware of the trusted high-speed encryption card that is actively measured by the BIOS is not corrupted, the option memory firmware of the trusted high-speed encryption card is triggered to measure the integrity of one or more firmware in the device. If the integrity of the one or more firmware is not corrupted, one or more firmware may be loaded. Otherwise, a system of the device is prohibited from being started, or the system is controlled to enter into a non-secure mode. 
     It is easy to note that a BIOS can be used to actively measure a trusted high-speed encryption card in a device when an integrity measurement result of the BIOS performed by a trusted security chip indicates that the integrity thereof is not corrupted. Furthermore, the trusted high-speed encryption card can be used to measure at least one firmware. A determination of whether a system of the device is started can be made based on a measurement result, and a measurement of a cryptographic operation can be performed based on a measurement key provided by the trusted security chip. Compared with the existing technologies, the trusted high-speed encryption card in the device can be actively measured, and the measurement of the cryptographic operation can be completed during a process of integrity measurement. This achieves the technical effects of an active measurement and a loading measurement of the cryptographic operation during a startup of the device in the process of integrity measurement by the trusted security chip. 
     Therefore, the solution of the foregoing second embodiment provided by the present disclosure solves the technical problems of failing to guarantee active measurements of a platform and a system, and loading measurements of cryptographic operations at the same time during a device startup in a process of performing an integrity measurement by a trusted security chip in the existing technologies. 
     In the foregoing embodiments of the present disclosure, before the BIOS actively measures the integrity of the trusted high-speed encryption card in the device, the method further includes the following steps. 
     Step S 66 : The trusted high-speed encryption card is powered on and started. 
     Step S 68 : A platform measurement root of the trusted high-speed encryption card is obtained. 
     Specifically, the platform measurement root may include measurement code(s) for performing integrity measurement(s) on the device. The platform measurement root may be loaded into a memory space of the device when the device is started at the first time, and loaded from the memory to the CPU of the device. It should be noted that, in order to ensure the accuracy of the platform measurement root that is obtained, the trusted high-speed encryption card can encrypt the platform measurement root to obtain a trusted measurement root, load the trusted measurement root into the memory of the motherboard, and then load the trusted measurement root is loaded from the memory into the CPU. 
     Step S 610 : A trusted security chip uses the platform measurement root and a key to perform an integrity measurement for the BIOS. 
     Optionally, a host processor stores a public key of a key pair, and the public key and a private key that encrypts the measurement root together form a pair of asymmetrical measurement keys. 
     In an optional solution, the host processor decrypts the trusted measurement root using the public key to obtain a measurement root. The measurement root includes a measurement code. The measurement code is executed to obtain a measurement result of the BIOS. The measurement result is then encrypted using the public key to obtain a processing result. The host processor sends the obtained processing result to the security chip. The security chip decrypts the encrypted measurement result using the private key (i.e., the private key that encrypts the measurement root), and the measurement result can thereby be obtained. When the system is started for the first time, the measurement result can be hashed to obtain a hash value, which is stored in a PCR of the trusted chip as a measurement reference value. When the system is started again, a hash value of a measurement result is compared with the measurement reference value. If the hash value of the measurement result is the same as the measurement reference value, a determination is made that the BIOS is complete, i.e., the integrity of the BIOS is not corrupted. If the hash value of the measurement result is different from the measurement reference value, a determination is made that the BIOS is incomplete, i.e., the integrity of the BIOS is corrupted, and so a platform and a system are considered to have destructive attacks. 
     It should be noted that the integrity of at least one firmware in a device can also be measured using the above method. 
     In the above embodiments of the present disclosure, when an integrity measurement of the BIOS indicates that the integrity is corrupted, the system of the device is forbidden from booting, or the system is controlled to enter into a non-secure mode. 
     In an optional solution, the integrity of a BIOS is measured during a startup of a device. If the integrity of the BIOS is compromised, a determination can be made that the BIOS is incomplete and the device is not trustable. A system of the device is forbidden from booting, or the system is controlled to enter into a non-secure mode, to ensure the security of the startup of the device. 
     In the above embodiments of the present disclosure, after the integrity of one or more firmware in the device is measured by the option memory firmware of the trusted high-speed encryption card at step S 64 , the method further includes the following steps. 
     Step S 612 , the option memory firmware of the trusted high-speed encryption card measures the integrity of a Boot Loader. 
     Specifically, the Boot Loader can be a program that runs before a system kernel or an application program runs. Using such program, a hardware device can be initiated, and a map of a memory space can be established, thereby bringing a hardware and software environment of the system to a suitable state, in order to prepare a correct environment for involving system kernels at the end. 
     In an alternative solution, the integrity of the Boot Loader can be measured using the method that measures the integrity of the BIOS as described above. 
     Step S 316 : The Boot Loader is triggered to measure the integrity of a system kernel of the device when the integrity of the Boot Loader measured by the option memory firmware of the trusted high-speed encryption card is not corrupted. 
     In an alternative solution, the integrity of the system kernel can be measured using the method that measures the integrity of the BIOS as described above. 
     Step S 616 : When the integrity of the Boot Loader measured by the option memory firmware of the trusted high-speed encryption card is corrupted, the system of the device is prohibited from booting, or the system is controlled to enter into a non-secure mode. 
     In an optional solution, during the startup of the device, after the firmware associated with the trusted high-speed cryptographic operation is loaded or the firmware booting peripherals of the other hardware devices is loaded, the integrity of the Boot Loader can be measured by Oprom of the trusted high-speed encryption card. If the integrity of the Boot Loader is not corrupted, the Boot Loader can be determined to be complete, and thereby the Boot Loader is executed. The integrity of the system kernel(s) of the device is measured by the Boot Loader. In response to determining that the integrity of the Boot Loader is corrupted, the Boot Loader can be determined to be incomplete, and the device is not trustable. Thus, the system of the device can be forbidden from being started, or the system is controlled to enter a non-secure mode, to ensure the security of the startup of the device. 
     In the foregoing embodiments of the present disclosure, after the Boot Loader is triggered to measure the system kernel of the device at step S 614 , the method may further include the following steps. 
     Step S 618 : A security boot system, and/or a control system enter(s) into a secure mode when the integrity of the system kernel measured by the Boot Loader is not corrupted. 
     Step S 620 : When the integrity of the system kernel measured by the Boot Loader is corrupted, the system of the device is prohibited from being started, or the system is controlled to enter into a non-secure mode. 
     In an optional solution, the integrity of the system kernel of the device can be measured by the Boot Loader in response to determining that the integrity of the Boot Loader is not corrupted. If the integrity of the system kernel is determined to be not corrupted, the system kernel can be determined to be complete, and the device is trustable. The device can be controlled to start up the system safely, and control the system to enter a secure mode. If determining that the integrity of the system kernel is corrupted, the system kernel can be determined to be incomplete, and the device is not trustable. The system of the device can be prohibited from being started, or the system is started to enter into a non-secure mode, to ensure the security of the startup of the device. 
     It should be noted that the foregoing method embodiments are all expressed as a series of action combinations for the sake of description. One skilled in the art should understand that the present disclosure is not limited by the described sequences of actions, because certain steps may be performed in other sequences or concurrently in accordance with the present disclosure. Furthermore, one skilled in the art should also understand that the embodiments described in the specification all belong to exemplary embodiments, and actions and modules that are involved may not be necessarily required by the present disclosure. 
     Through the description of the above embodiments, one skilled in the art can clearly understand that the methods according to the foregoing embodiments can be implemented using software plus a necessary general hardware platform, and apparently can also be implemented by hardware. In many cases, the former is a better implementation. Based on such understanding, the essence of the technical solutions of the present disclosure or the parts that contribute to the existing technologies may be embodied in a form of a software product.

     Specifically, the first preset condition may be the integrity of the BIOS being not corrupted. After comparing a hash value of the BIOS with a preset hash value, a determination of whether the integrity of the BIOS is corrupted may be made. When the integrity of the BIOS is not corrupted, the first measurement result is determined to satisfy the first preset condition. 
     Step S 156 : Obtain a second measurement result, wherein the second measurement result is obtained based on at least one firmware in the device measured by the BIOS. 
     Optionally, the firmware may include at least one of: a trusted high-speed cryptographic algorithmic firmware, a peripheral storage device, a memory, and a hardware device. 
     Specifically, a building architecture of a chain of trust based on a trusted high-speed encryption card is proposed.  FIG. 4  shows a measurement of a building architecture of a chain of trust based on a BIOS extension, which can modify a BIOS of a OEM server manufacturer to enable the BIOS to actively measure ROM and other hardware firmware of all peripherals. 
     It should be noted that the integrity measurement method of at least one firmware is consistent with the integrity measurement method of the BIOS. 
     Step S 158 : Determine that the second measurement result satisfies a second preset condition. 
     Specifically, the second preset condition may be the integrity of the at least one firmware being not corrupted. After comparing a hash value of the at least one firmware with a preset hash value, a determination of whether the integrity of the at least one firmware is corrupted may be made. The second measurement result is determined to satisfy the second predetermined condition if the integrity of the at least one firmware is not corrupted. 
     Step S 1510 : Load one or more firmware. 
     In an optional solution, in order to implement an integrity measurement of a device, a trusted security chip may measure the integrity of a BIOS during a process of device startup. If a result of the integrity measurement of the BIOS indicates that the integrity thereof is not corrupted, the BIOS can be used to actively measure a firmware associated with a trusted high-speed cryptographic operation, such as the integrity of a cryptographic algorithmic operation, and may also actively measure the integrity of ROM of hardware peripherals and firmware thereof to determine whether the firmware integrity of the firmware associated with the trusted high-speed cryptographic operation and other hardware devices is corrupted. If no corruption exists, the firmware associated with the trusted high-speed cryptographic operation can be loaded, or firmware boot peripherals of the other hardware devices can be loaded. 
     The method provided in the foregoing ninth embodiment of the present disclosure measures the integrity of a BIOS to obtain a first measurement result. In a case that the first measurement result meets a first preset condition, the BIOS can be used to actively measure at least one firmware in a device. One or more firmware may be loaded upon determining that a second measurement result satisfies a second preset condition. 
     It is easy to note that a BIOS can actively measure at least one firmware in a device through when an integrity measurement result of the BIOS performed by a trusted security chip indicates that the integrity thereof is not corrupted, and a determination of whether to start the device can be made according to a measurement result. A measurement of a cryptographic operation can be completed based on a measurement key provided by the trusted security chip. Compared with the existing technologies, at least one firmware in a device can be actively measured, and a measurement of a cryptographic operation can be completed when an integrity measurement is performed, thus achieving the technical effects of guaranteeing active measurements and a loading measurement of the cryptographic operation at the time of device startup when the integrity measurement is performed by a trusted security chip. 
     Therefore, the solution provided by the ninth embodiment of the present disclosure solves the technical problems of failing to guarantee active measurements of a platform and a system, and loading measurements of cryptographic operations at the same time during a device startup in a process of performing an integrity measurement by a trusted security chip in the existing technologies. 
     In the foregoing embodiments of the present disclosure, before the BIOS actively measures the at least one firmware in the device to obtain the second measurement result at step S 156 , the method may further include the following steps. 
     Step S 1512 : Power on and start a trusted high-speed encryption card. 
     Step S 1514 : Obtain a platform measurement root of the trusted high-speed encryption card. 
     Specifically, the platform measurement root may include measurement code(s) for performing integrity measurement(s) on the device. The platform measurement root may be loaded into a memory space of the device when the device is started at the first time, and loaded from the memory to the CPU of the device. It should be noted that, in order to ensure the accuracy of the platform measurement root that is obtained, the trusted high-speed encryption card can encrypt the platform measurement root to obtain a trusted measurement root, load the trusted measurement root into the memory of the motherboard, and then load the trusted measurement root is loaded from the memory into the CPU. 
     Step S 1516 : A trusted security chip uses the platform measurement root and a key to perform an integrity measurement for the BIOS. 
     Optionally, a host processor stores a public key of a key pair, and the public key and a private key that encrypts the measurement root together form a pair of asymmetrical measurement keys. 
     In an optional solution, the host processor decrypts the trusted measurement root using the public key to obtain a measurement root. The measurement root includes a measurement code. The measurement code is executed to obtain a measurement result of the BIOS. The measurement result is then encrypted using the public key to obtain a processing result. The host processor sends the obtained processing result to the security chip. The security chip decrypts the encrypted measurement result using the private key (i.e., the private key that encrypts the measurement root), and the measurement result can thereby be obtained. When the system is started for the first time, the measurement result can be hashed to obtain a hash value, which is stored in a PCR of the trusted chip as a measurement reference value. When the system is started again, a hash value of a measurement result is compared with the measurement reference value. If the hash value of the measurement result is the same as the measurement reference value, a determination is made that the BIOS is complete, i.e., the integrity of the BIOS is not corrupted. If the hash value of the measurement result is different from the measurement reference value, a determination is made that the BIOS is incomplete, i.e., the integrity of the BIOS is corrupted, and so a platform and a system are considered to have destructive attacks. 
     In the foregoing embodiments of the present disclosure, upon determining that the first measurement result does not satisfy the first preset condition, or the second measurement result does not satisfy the second preset condition, the system of the device is prohibited from booting, or the system is controlled to enter into a non-secure mode. 
     In an optional solution, in order to implement an integrity measurement of a device, an integrity measurement of a BIOS may be performed by a trusted security chip during a startup process of the device. When a result of the integrity measurement of the BIOS indicates that the integrity thereof is not corrupted, a firmware associated with a trusted high-speed cryptographic operation, such as the integrity of a cryptographic algorithm, can be actively measured by the BIOS, and the integrity of a ROM of a hardware peripheral and its firmware can also be actively measured, to determine whether a firmware integrity of the firmware associated with the trusted high-speed cryptographic operation and other hardware devices is corrupted. If a corruption exists, a system of the device is prevented from being started, or the system is started as a non-secure mode, to ensure the security of a device startup. 
     In the foregoing embodiments of the present disclosure, measuring the integrity of the BIOS in the device at step S 152  includes: 
     Step S 1522 : Determine whether a hash value of the BIOS is the same as a preset hash value. 
     Specifically, the preset hash value may be a hash value of the BIOS calculated when the device is powered on. If these two are the same, this indicates that the integrity of the BIOS is not corrupted. Otherwise the integrity of the BIOS is corrupted.

When the integrity of one or more firmware in the device measured by the BIOS is not corrupted, the one or more firmware may be loaded. When the integrity of one or more firmware in the device measured by the BIOS is corrupted, a system of the device may be forbidden from being started up, or the system may be controlled to enter into a non-secure mode. 
     It is easy to note that a BIOS can actively measure at least one firmware in a device when an integrity measurement result performed by a trusted security chip for the BIOS indicates that the integrity thereof is not corrupted, and a determination of whether to start a system of the device is made based on a measurement result.
