In some embodiments, methods may include receiving a wrapped computer application via a first secure communication connection from a first remote server, authenticating the first secure communication connection, modifying the wrapped computer application based at least in part on the authenticating, and transmitting the wrapped computer application via a second secure communication connection to a second remote server based at least in part on the modifying.

## Background
BACKGROUND
Advancements in media delivery systems and data-related technologies require additional security for electronic applications—including mobile applications. This additional security may be designed to protect the mode of communication between entities or devices, or the electronic applications themselves. Often an entity is required to or desires to sign and certify an electronic application. But current methods for certification and signing require the exchange of otherwise private, confidential, and sensitive information by requiring an entity to transmit their private information—such as a key—to another entity. In some cases this exchange may lead to inadvertent or insidious disclosure of this private information. Or, in other cases, some third party entities may have terms, service, and/or other restrictions that limit what information a signing entity can share with others.
Because of current systems' limitations, a need exists for an entity to certify and/or sign electronic applications and then transmit these certified and/or signed applications to other entities that perform additional functions, such as wrapping the electronic application, with having to pursue costly, time-intensive alternatives. In some cases, a need exists for a signing entity to be able to sign an application, another entity to wrap the application, and the signing entity to sign the then-wrapped application. Accordingly, the present systems and methods address these and other related problems, particularly those related to signing and/or certifying wrapped applications.

DETAILED DESCRIPTION
The systems and methods described here relate to application wrapping techniques, and/or signing and/or certifying applications. In some embodiments, the systems and methods described here relate to signed applications, application wrapping techniques, and/or re-signing and/or re-certifying then-wrapped applications.
In some embodiments, wrapping an application may include changing an application—including a mobile application—by inserting, revising, altering, and/or amending code in that application. In some embodiments, wrapping may include inserting one or more policies. Sometimes a first entity develops an application but a second entity may wrap the application—each performing discrete functions and playing to each entity's strengths.
For example, in some embodiments, the first entity may understand and develop applications, such as mobile applications, but may not understand the nuances and the requirements of security, have the capability to perform and/or modify cryptographic or other security-related features, may use a second entity's software as a service (SaaS) platform for efficiency, and/or other reasons. Applications may be signed to verify the signing entity (avoiding malicious applications), using a remote signing service (RSS). Sometime already-signed applications may need to be modified by wrapping or another means, and then the previously signed applications must be re-signed by the same (or a different) entity.
The re-signing or the re-certifying (or if the application is unsigned/uncertified, the signing or the certifying) is most often performed by the first entity that developed the application, by using one or more signature keys—such as a cryptographic key. In some embodiments, this first entity signs the application using confidential information, sends the application to a second entity to wrap the application, and/or the second entity sends the wrapped application to the first entity to re-sign and/or re-certify. In some embodiments, the first entity sends an application that has not been signed before it is wrapped by the second entity. The present systems and methods include aiding the signing/re-signing and/or the certifying/re-certifying of already-wrapped applications.
The present methods and systems provide ways for entities to be able to work together while protecting the certification and/or the signing information. For example, by allowing a first entity to re-sign and/or re-certify an already wrapped application the first entity can still use the second entity's SaaS platform with ease. In some embodiments, the re-signing of wrapped applications that were previously uploaded in a SaaS environment may be performed through a signing service hosted on premises at a customer's site (e.g., via a RSS unit).
In some embodiments, this RSS is performed via a RSS software application that may run via and/or on one or more computers, a RSS server, a RSS protected personal computer, and/or some other computing device.
In some embodiments, the RSS device and the SaaS device may connect and/or communication through a “pull” function (e.g., a request, etc.), a “push” function (e.g., a notification, etc.), and/or some other method. In some embodiments, the RSS device may fetch the required information. In some embodiments, the devices may connect and/or communicate automatically—through an automated method—based at least in part on a “pull” function, a “push” function, and/or some other method. The terms device and entity are related in this disclosure unless otherwise noted and relate to an entity (e.g., a company, an individual, etc.) that controls a device (e.g., a computer, a server, etc.).
In some embodiments, the communication link between the RSS device and the SaaS device may be a secure communication link. This secure communication link may require authentication, encryption, and/or both. The communications between the RSS device and the SaaS device may include multiple secure communications between them and/or other devices. These secure communications—transmitted and/or received via secure communication links—may be performed using one communication link to perform all the required functions or multiple communication links.
In some embodiments, the RSS and the SaaS may both use authentication. In some embodiments, the authentication may use one or more public-private authentication key pairs. Where multiple authentication key pairs are created and/or used at least some of the authentication key pairs may pertain to the RSS device (or entity) and/or at least some of the authentication key pairs may pertain to the SaaS device (or entity). In some embodiments, the device and/or the entity-specific authentication key pairs are known only to one entity, and not others. For example, a first authentication key pair specific to the RSS device may not be known to the SaaS device. As another example a private part of the first key pair specific to the RSS device and/or entity may not be known to the SaaS device and/or entity, but a public part of the first key pair specific to the RSS device and/or entity may be known to the SaaS device and/or entity.
In some embodiments, a public part of the RSS device's authentication key pair would be communicated to the SaaS device, while the private part of the RSS device's authentication key pair would not be communicated to the SaaS device. In some embodiments, a public part of the SaaS device's authentication key pair would be communicated to the RSS device, while the private part of the SaaS device's authentication key pair would not be communicated to the RSS device.
In some embodiments, a dual authentication may occur, which may include authenticating the RSS device and authenticating the SaaS device. In some embodiments, authentication may require multiple pieces of information to be verified. For example, the RSS device may authenticate a communications link by verifying a person or an entity associated with the SaaS device, a tenant associated with the SaaS device, and/or verifying a server or a device (which may or may not be related to the SaaS device—such as a server). In some embodiments, this authentication may include using a username and/or a password. In some embodiments, this authentication may include using a secret and/or an API key. In some embodiments, this authentication may include using an authentication key pair—which may include generating a key pair specifically related to each entity and/or device. In some embodiments, this authentication may include a client certified authenticated secure sockets layer (SSL) connection.
In some embodiments, every communication between devices related to an application may be authenticated. In some embodiments, communications relating to signed applications and/or other communications may be authenticated. In some embodiments, communications relating to wrapped applications and/or other communications may be authenticated. In some embodiments, communications relating to re-signed applications and/or other communications may be authenticated.
In some embodiments, the SaaS device may receive an application that may or may not have been signed and/or certified before the SaaS device received it. In some embodiments, after an application is wrapped (and/or re-wrapped), the wrapping entity (e.g., a SaaS entity, etc.) may provide one or more certificates for another entity (e.g., a RSS entity, etc.) to sign and/or resign. In some embodiments, the wrapping entity may sign the certificate before providing the certificate to the other entity. In some embodiments, the wrapping entity may sign the certificate using one or methods (e.g., including using a key having at least one of a public key and a private key, etc.).
In some embodiments, a wrapped computer application includes applications designed for network computers, servers, personal computers, mobile device applications, tablet computers, smartphones, computing units, and/or other devices that use computing technology
In some embodiments, the RSS device and/or entity pulls an application—such as a wrapped application—from the SaaS device and/or entity. The RSS device and/or entity may then sign and/or certify the application. The RSS device and/or entity may then push the then-certified (and in some cases wrapped) application to a SaaS device and/or entity.
In some embodiments, the SaaS device and/or entity pushes an application—such as a wrapped application—from the SaaS device and/or entity. The RSS device and/or entity may then sign and/or certify the application. The RSS device and/or entity may then push the then-certified (and in some cases wrapped) application to a SaaS device and/or entity.
In some embodiments, the pushing and/or the pulling of an application may be based on an elapsed time (e.g., every 3, 5, or 10 seconds), a notification (e.g., the RSS device would receive a notification that a wrapped application is ready), a request (e.g., the RSS device would make a request to another device about the availability of a wrapped application), and/or some other related method. In some embodiments, one or more of the devices and/or entities may store and/or receive a notification about the length of the elapsed time intervals. For example, if the RSS device initiates a pull every 5 seconds, then both the RSS and the SaaS devices may know and/or store this interval.
In some embodiments, at least one of the devices and/or entities may adjust the elapsed time interval—including requests for pulling and/or pushing—based at least in part on one or more performance parameters, including past performance. For example, if a RSS device is unsuccessful in pulling an application after X number of pull requests and/or over an interval of length Y, the RSS device (as an example) may adjust the elapsed time interval based at least in part on the X number of pull requests and/or the length Y, among other parameters—increase system performance and decreasing system requirements.
In some embodiments, the secure communications between the two devices and/or entities may be performed based on a single secure connection, which may be uninterrupted. In some embodiments, the single secure connection may include authenticating the connection at least one time. In some embodiments, the single secure connection may include authenticating the connection more than one time and authenticating the connection may occur based on one or more parameters. These parameters may include, among other things, time, system performance and/or characteristics, device performance and/or characteristics, connection performance and/or characteristics, etc.
In other embodiments, the secure communications between the two devices and/or entities may be performed based on multiple secure connections—including multiple secure connections running in series and/or in parallel. In some embodiments, at least some of the multiple secure connections may require authentication. In other embodiments, every secure connection may require authentication.
In some embodiments, after a device and/or an entity (e.g., the RSS unit) signs and/or certifies (or re-signs and/or re-certifies) an application, another device and/or entity (e.g., the SaaS unit) may use information to verify the device and/or entity that signed and/or certified the application. This information may include, among other things, information relating to a signature key pair. For example, the SaaS device may use a previously used and/or a new key public key as part of a signature key pair to verify the device and/or entity that signed and/or certified the application. In some embodiments, the SaaS device may obtain the previously used and/or the new key public key from the RSS device.
In some embodiments, a RSS unit may have an authenticated persistent duplex connection and/or polling connection to a SaaS unit. A customer may communicate an application package to be distributed to a SaaS device for wrapping. After wrapping, the application package may be communicated to a RSS device—which may in some embodiments be located on premises at a customer site. In some embodiments, the RSS device may then sign and/or certify (or re-sign and/or re-certify) the application package using confidential information, such as a private signature key. After signing is complete, the now-signed (or now-resigned) application package may be communicated to a SaaS unit through the authenticated persistent connection.
In some embodiments, a RSS unit may include a RSS server. In some embodiments, a SaaS unit may include a SaaS server. In some embodiments, a RSS unit may include an on premises server and/or computing unit (located at a customer site and/or a related site) with knowledge of a customer's private key, among other things. The RSS unit may or may not be associated with a particular customer account. In some embodiments, a SaaS unit may include a unit hosting an application delivery platform for computing devices (e.g., mobile devices), among other things.
In some embodiments, in addition to or instead of authentication, other security measures may be carried out. In some embodiments, an administrator may authenticate and/or sign-in to a designated SaaS device and/or tenant. In some embodiments, an administrator may upload an application package (that may or may not include an Android application package (APK) and/or an IPA) to their SaaS device and/or tenant. In some embodiments, a module on the SaaS device and/or tenant may sign the application package with a SaaS-issued signing certificate unique to the tenant (where this SaaS-issued signing certificate may be created and/or provisioned during customer on-boarding). In some embodiments, the signed application package may be delivered to the on-premise service that may then validate the signature of the application package to ensure that it originated from the proper SaaS servers and/or tenants. In some embodiments, the on-premise service may re-sign the application package with a signature key. In some embodiments, the on-premise service may deliver a final signed application package back to the SaaS device and/or tenant for distribution to enrolled end-users (e.g., mobile end-users) and/or perform other actions.

This notification and/or transmission may be sent to one or more components and/or elements of system 200, 100, and/or others.
In some embodiments, RSS unit 205 may include an authentication module 225 that may facilitate authenticating one or more connections, devices, entities, sources, applications, confidential information (e.g., public and/or private keys), certificates, etc. In some embodiments, authentication module 225 helps facilitate secure communication between multiple entities and/or devices. For example, authentication module 225 may facilitate communication between a RSS unit (e.g., RSS unit 205) and a computing unit (e.g., first computing unit 120). As another example, authentication module 225 may facilitate communication between a RSS unit (e.g., RSS unit 205) and a SaaS unit (e.g., SaaS unit 210).
In some embodiments, communication module 215 may facilitate secured communication at least in part based on communication with authentication module 225. Authentication module 225 may independently perform all actions relating to authentication relating to the systems and/or methods described in this disclosure. Or, in some cases, authentication module 225 may perform actions relating to authentication relating to the systems and/or methods described in this disclosure in conjunction with other components and/or elements of other systems.
In some embodiments, authentication module 225 may generate confidential information. In some embodiments, authentication module 225 may generate one or more authentication keys. These one or more authentication keys may include any information related to authentication. In some embodiments, an authentication key may include multiple parts, including a private key and/or a public key.
In some embodiments, authentication module 225 may receive confidential information from another device and/or entity. In some embodiments, authentication module 225 may receiver one or more authentication keys from another device and/or entity.
In some embodiments, the private key and/or the public key may be known only by and/or only possessed by the key-holding entity (other than a separate entity that may have issued the keys). For example, a RSS unit 205 may generate, store and/or receive a private key specific to RSS unit 205 and/or a related entity. This private key may be a uniquely assigned identifier.
In some embodiments, RSS unit 205 may include modification module 235. Modification module 235 may modify an application related to RSS unit 205, SaaS unit 210, and/or other applications. In some embodiments, modification module 235 may modify one or more wrapped applications and/or unwrapped applications. In some embodiments, modifying an application may include modifying, adding, amending, changing, certifying, and/or signing an application, including a certificate, among other things.
A certificate may be a certificate generated and/or added to the application by RSS unit 205 and/or a certificate generated and/or added to the application by the SaaS unit. For example, in wrapping an application SaaS unit 210 may add a certificate to an application and then the wrapped application (now having one or more certificates) may be received and modified by RSS unit 205 via modification module 235. In some embodiments, modifying an application includes signing an application with a signature key, which may only be known by the signing entity.
In some embodiments, an unwrapped application may be transmitted from RSS unit 205 to SaaS unit 210. This unwrapped application may include an identifier, such as an identification key. In some embodiments, the identifier may include information specific to RSS unit 205 and/or the related entity. For example, the identifier may include a unique identification key—such as a signature—assigned to RSS unit 205 and/or entity. This identifier may only be known to RSS unit 205 and/or the related entity. In some embodiments, the identification key may include a signature key.
After RSS unit 205 receives a wrapped application it may modify the wrapped application via modification module 235. In some embodiments, this modification may include using a signature key that may or may not relate to one or more certificates. This signature may be the same as or different from an identifier (e.g., identification key) used with one or more previously transmitted applications—including wrapped and/or unwrapped applications.
In some embodiments, RSS unit 205 may include memory 245. In some embodiments, memory 245 may include computer executable instructions that can be executed by one or more processors. These one or more processors may be present in an element of RSS unit 205 (e.g., communication module 215, authentication module 225, and/or modification module 235) and/or one or more other components of system 200 or other systems (e.g., system 100).
In some embodiments, memory 245 may include computer executable instructions that may cause RSS unit 205 to interact with one or more components of system 200, such as SaaS unit 210. In some embodiments, memory 245 may contain, among other code, the Basic Input-Output system (BIOS) which controls basic hardware operation such as the interaction with peripheral components or devices.

FIG. 9 depicts a block diagram of a controller 900 suitable for implementing the present systems and methods. The controller 900 may be an example of a RSS unit, a SaaS unit, a computing unit, and/or other units. In some embodiments, controller 900 includes a bus 905 which interconnects components and/or elements of controller 900 including one or more of: a central processor 910, a system memory 915 (which may include random access memory (RAM), read-only memory (ROM), flash RAM, and/or similar memory), an input/output controller 920, an external audio device, such as a speaker system 925 via an audio output interface 930, an external device, such as a display screen 935 via display adapter 940, an input device 945 (e.g., remote control device interfaced with an input controller 950), a USB device 965 (in some cases interfaced with a USB controller 970), and a storage interface 980. Also included are at least one sensor 955 connected to bus 905 through a sensor controller 960 and a network interface 985 (in some cases coupled directly to bus 905).
Bus 905 allows data communication between central processor 910, system memory 915 (which may include ROM, flash memory, RAM, and/or similar memory, as previously noted), and/or other elements. One type of memory, such as RAM, may be the main memory into which the operating system and application programs are loaded. The ROM and/or the flash memory can contain, among other code, the Basic Input-Output system (BIOS) that controls basic hardware operation such as the interaction with peripheral components or devices. For example, the different modules (e.g., communication, authentication, modification, wrapping, feedback, and/or others) to implement the present systems and methods may be stored within the system memory 915. Applications resident with controller 900 are generally stored on and accessed via a non-transitory computer readable medium, such as a hard disk drive (e.g., fixed disk 975) and/or other storage medium. Additionally, applications can be in the form of electronic signals modulated in accordance with the application and data communication technology when accessed via interface 985.
Storage interface 980, as with the other storage interfaces of controller 900, can connect to a standard computer readable medium for storage and/or retrieval of information—such as a fixed disk drive 975. Fixed disk drive 975 may be a part of controller 900 or may be separate and accessed through other interface systems. Network interface 985 may provide a direct connection to a remote server via a direct network link to the Internet via a POP (point of presence). Network interface 985 may provide such connection using wireless techniques, including digital cellular telephone connection, Cellular Digital Packet Data (CDPD) connection, digital satellite data connection, or the like. In some embodiments, one or more sensors (e.g., device sensors, network sensors, system sensors, authentication sensors, communication sensors, and/or power sensors, etc.) connect to controller 900 wirelessly via network interface 985.
Many other devices or subsystems may be connected in a similar manner (e.g., computing device, remote devices, transmitters, etc.). In addition, all of the devices shown in FIG. 9 need not be present to practice the disclosed systems and methods. The devices and subsystems can be interconnected in different ways from that shown in FIG. 9. Some aspects of some operations of a system, such as that shown in FIG. 9, may be readily known in the art and are not discussed in detail in this application.
Code to implement the present disclosure can be stored in a non-transitory computer-readable medium such as one or more of system memory 915 or fixed disk 975. The operating system provided on controller 900 may be iOS®, ANDROID®, MS-DOS®, MS-WINDOWS®, OS/2®, UNIX®, LINUX®, and/or another known operating system.
Moreover, regarding the signals described herein, those skilled in the art will recognize that a signal can be directly transmitted from a first block to a second block, or a signal can be modified (e.g., amplified, attenuated, delayed, latched, buffered, inverted, filtered, or otherwise modified) between the blocks. Although the signals of the above described embodiments may be characterized as communicated from one block to the next, other embodiments of the present systems and methods may include modified signals in place of such directly communicated signals as long as the informational and/or functional aspect of the signal is communicated between blocks. To some extent, a signal input at a second block can be conceptualized as a second signal derived from a first signal output from a first block due to physical limitations of the circuitry involved (e.g., there will inevitably be some attenuation and delay). Therefore, as used here, a second signal derived from a first signal includes the first signal and/or any modifications to the first signal—whether due to circuit limitations or due to passage through other circuit elements which do not change the informational and/or final functional aspect of the first signal.
While this disclosure sets forth various embodiments using specific block diagrams, flowcharts, and examples, each block diagram component, flowchart step, operation, and/or components described and/or illustrated here may be implemented—individually and/or collectively—using a wide range of hardware, software, and/or firmware (or any combination thereof) configurations. In addition, any disclosure of components contained within other components should be considered exemplary in nature since many other architectures can be implemented to achieve the same functionality, including combining multiple elements in one or more unitary and/or separate structures.
The process parameters and sequence of steps described and/or illustrated here are given by way of example only and can be varied as desired. For example, while the steps illustrated and/or described herein may be shown or discussed in a particular order, these steps do not necessarily need to be performed in the order illustrated or discussed. The various exemplary methods described and/or illustrated here may also omit one or more of the steps described and/or illustrated, and/or may include additional steps in addition to those disclosed.
Furthermore, while various embodiments have been described and/or illustrated herein in the context of fully functional computing systems, one or more of these exemplary embodiments may be distributed as a program product in a variety of forms, regardless of the particular type of computer-readable media used to actually carry out the distribution. The embodiments disclosed herein may also be implemented using software modules that perform certain tasks. These software modules may include script, batch, or other executable files that may be stored on a computer-readable storage medium or in a computing system. In some embodiments, these software modules may configure a computing system to perform one or more of the exemplary embodiments disclosed herein.
