     DESCRIPTION OF EMBODIMENTS 
     The exemplary embodiments of the present disclosure are described below in conjunction with accompanying drawings, including various details of the embodiments of the present disclosure to facilitate understanding, which should be considered only exemplary. Therefore, those skilled in the art should recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Likewise, for clarity and conciseness, description of well-known functions and structures are omitted from the following description. 
     In the embodiments of the present disclosure, “at least one” refers to one or more, and “multiple” refers to two or more. “And/or” describes an association relationship of associated objects, indicating that there may be three types of relationships, for example, A and/or B, which can mean that there are three cases: A exists alone, A and B exist at the same time, and B exists alone, in which A and B can be singular or plural. In the text description of the present disclosure, the character “/” generally indicates that front and rear associated objects are in an “or” relationship. 
     The technical solution provided by the embodiments of the present disclosure may be applied in a scenario of V2X device communication. At present, a number of intelligent transportation cities supporting V2X technology have emerged. Each intelligent transportation city has its own mutual trust platform. V2X devices in the intelligent transportation city can communicate based on a trusted root certificate list corresponding to the mutual trust platform. 
     Taking an intelligent transportation city A and an intelligent transportation city B as an example, both the intelligent transportation city A and the intelligent transportation city B have their own mutual trust platforms, namely a mutual trust platform A and a mutual trust platform B. V2X devices in the intelligent transportation city A can communicate based on a trusted root certificate list corresponding to the mutual trust platform A; similarly, V2X devices in the intelligent transportation city B can communicate based on a trusted root certificate list corresponding to the mutual trust platform B. However, because the trusted root certificate lists of the intelligent transportation city A and the intelligent transportation city B are both independent and cannot communicate with each other, when V2X vehicles in the intelligent transportation city A travel to the intelligent transportation city B, they cannot communicate with V2X devices in the intelligent transportation city B. 
     The mutual trust platform may be a network device or a cloud server, etc., which can be used to manage relevant information of a local certificate system and a certificate of an external certificate system in an intelligent transportation area. For example, an example is taken where a city is an intelligent transportation area, a mutual trust platform corresponding to the city may maintain a trusted root certificate list, the trusted root certificate list includes a root certificate of the local certificate system and a download address of a trusted domain certificate list. 
     In order to enable the V2X vehicles in the intelligent transportation city A to communicate with the V2X devices in the intelligent transportation city B when travelling to intelligent transportation city B, it can be considered to acquire the trusted root certificate list corresponding to the mutual trust platform B, so that the V2X vehicles in the intelligent transportation city A can communicate with the V2X devices in the intelligent transportation city B based on the trusted root certificate list corresponding to the mutual trust platform B. However, how to acquire the trusted root certificate list of the intelligent transportation city B for the V2X vehicles in the intelligent transportation city A is an urgent problem to be solved. 
     In order to enable the V2X vehicles in the intelligent transportation city A to acquire the trusted root certificate list corresponding to the mutual trust platform B, it can be considered to set a higher-level global authority for managing the mutual trust platform A corresponding to the intelligent transportation city A and the mutual trust platform B corresponding to the intelligent transportation city B, such as a global platform. Exemplarily, as shown in  FIG. 1 ,  FIG. 1  is a schematic architecture diagram of a communication system provided by an embodiment of the present disclosure. The communication system shown in  FIG. 1  may include the mutual trust platform A, the mutual trust platform B and a global platform, where the trusted root certificate list corresponding to the mutual trust platform A is different from the trusted root certificate list corresponding to the mutual trust platform B. The global platform in  FIG. 1  can be used to maintain a corresponding relationship between trusted mutual trust platforms and areas, and download addresses of the trusted root certificate lists corresponding to the mutual trust platforms. Exemplarily, the maintained content can be recorded in a file of the mutual trust platform list, and the V2X vehicles in the intelligent transportation city A can regularly acquire the mutual trust platform list from the global platform, so that when the V2X vehicles in the intelligent transportation city A travels to an area of the intelligent transportation city B, the download address of the trusted root certificate list corresponding to the mutual trust platform B can be determined through a pre-acquired mutual trust platform list, and the trusted root certificate list can be downloaded and acquired based on the download address of the trusted root certificate list, so that the V2X vehicles in the intelligent transportation city A can communicate with the V2X devices in the intelligent transportation city B based on the trusted root certificate list, thereby realizing communication between the V2X vehicles in the intelligent transportation city A and the V2X devices in the intelligent transportation city B. 
     Based on the above technical concept, the embodiments of the present disclosure provide a communication method for a vehicle. Next, the communication method for a vehicle provided by the present disclosure will be described in detail through specific embodiments. It can be understood that the following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. 
     Embodiment 1 
       FIG. 2  is a schematic flowchart of a communication method for a vehicle according to a first embodiment of the present disclosure. The communication method for the vehicle may be executed by a software and/or a hardware apparatus, and the hardware apparatus may be a vehicle. Exemplarily, as shown in  FIG. 2 , the communication method for the vehicle may include the following steps. 
     S 201 : when it is determined that the vehicle travels to a target area, determine a target platform corresponding to the target area and a target download address corresponding to the target platform according to a corresponding relationship between mutual trust platforms and areas, and download addresses corresponding to the mutual trust platforms. 
     A mutual trust platform corresponding to the target area and a mutual trust platform corresponding to an area to which the vehicle belongs are different mutual trust platforms, and access verification information corresponding to different mutual trust platforms is different, that is, access verification systems corresponding to different mutual trust platforms are different. 
     Exemplarily, the corresponding relationship between the mutual trust platforms and the areas, and the download addresses corresponding to the mutual trust platforms may be download and acquired from a global platform when the vehicle executes the technical solution of the present disclosure, or downloaded and acquired from the global platform before the vehicle executes the technical solution of the present disclosure. After acquiring the corresponding relationship between the mutual trust platforms and the areas, and the download addresses corresponding to the mutual trust platforms, the vehicle saves the corresponding relationship between the mutual trust platforms and the areas, and the download addresses corresponding to the mutual trust platforms locally, so that the vehicle can directly search and acquire the corresponding relationship between the mutual trust platforms and the areas, and the download addresses corresponding to the mutual trust platforms locally when executing the technical solution of the present disclosure. 
     It can be understood that in the embodiment of the present disclosure, the global platform can maintain the corresponding relationship between the mutual trust platforms and the areas, and the download addresses corresponding to the mutual trust platforms through a mutual trust platform list, correspondingly, the vehicle acquires the mutual trust platform list from the global platform; the global platform can also maintain the corresponding relationship between the mutual trust platforms and the areas, and the download addresses corresponding to the mutual trust platforms in a form of mutual trust platform list; or the corresponding relationship between the mutual trust platforms and the areas, and the download addresses corresponding to the mutual trust platforms may also be maintained in other ways, which can be specifically set according to actual needs. 
     Taking maintaining the corresponding relationship between the mutual trust platforms and the areas, and the download addresses corresponding to the mutual trust platforms through the mutual trust platform list as an example, in addition to the corresponding relationship between the mutual trust platforms and the areas, and the download addresses corresponding to the mutual trust platforms, the mutual trust platform list may also include a root certificate of a trusted root certificate list authority of each mutual trust platform, an registration service interface address provided by each trusted mutual trust platform for the vehicle, and a name and a code of an area managed by each mutual trust platform and so on, which can be specifically set according to the actual needs. 
     It can be understood that in the embodiments of the present disclosure, since information of the mutual trust platform may change, for example, the download address corresponding to the mutual trust platform may change. Therefore, the global platform may update the mutual trust platform list based on the download address corresponding to the changed mutual trust platform, and in order to ensure that the vehicle can acquire the latest mutual trust platform list, the vehicle can regularly download and acquire the mutual trust platform list from the global platform, so as to acquire the latest corresponding relationship between the mutual trust platforms and the areas, and the download addresses corresponding to the mutual trust platforms. 
     When it is determined that the vehicle travels to a target area, determining the target platform corresponding to the target area and the target download address corresponding to the target platform according to the corresponding relationship between mutual trust platforms and areas, and download addresses corresponding to the mutual trust platforms acquired. It can be understood that after acquiring the target download address corresponding to the target platform, the vehicle cannot download access verification information only according to the target download address corresponding to the target platform, but needs to acquire download verification information generated by the target platform for the vehicle and combine the target download address with the download verification information generated by the target platform for the vehicle, that is, the vehicle executes the following S 202  and S 203 . 
     S 202 : acquire download verification information generated by the target platform for the vehicle. 
     Exemplarily, in the embodiment of the present disclosure, the download verification information may be a security certificate which is used as a certificate for identity authentication during an interaction between the vehicle and the mutual trust platforms, and the security certificate may be used as a passage certificate of the vehicle in the target area, such as AccessToken. 
     Exemplarily, when the vehicle acquires the download verification information generated by the target platform for the vehicle, if the vehicle travels to the target area for a first time, it can send a registration request message to the target platform; where the registration request message includes registration verification information of the vehicle to enable the target platform to verify an identity of the vehicle based on the registration verification information; exemplarily, the registration verification information may issue an initial security certificate for the vehicle in the area to which the vehicle belongs, such as an X509 certificate. The security certificate can prove the identity of the vehicle, and the area to which the vehicle belongs can be determined according to the security certificate. The registration request message may also include identification information of the vehicle, such as a vehicle identification number (Vehicle Identification Number, VIN) or license plate information; after the verification of the identity of the vehicle is successful, the target platform generates, for the vehicle, the download verification information of the vehicle for travelling in the target area, and then sends a registration response message to the vehicle; where the registration response message includes the download verification information of the vehicle to enable the vehicle to acquire the download verification information. It can be understood that generally, the download verification information has a valid period of use. Therefore, after acquiring the download verification information, the vehicle may save the download verification information locally. If the vehicle travels to the target area again within the valid period of use, it can directly acquire the download verification information locally (from the vehicle itself) without sending the registration request message to the target platform, so there is no need to interact with the target platform, thereby improving efficiency of acquiring the download verification information. 
     It can be understood that in the embodiment of the present disclosure, before sending the registration request message to the target platform to request the download verification information generated by the target platform for the vehicle, the vehicle can also verify the identity of the target platform, and send the registration request message to the target platform after the verification is successful, to request the target platform to generate download verification information for the vehicle. 
     In this way, after acquiring the download verification information generated by the target platform for the vehicle and the target download address corresponding to the target platform respectively, the vehicle can execute the following S 203 . 
     S 203 : download access verification information in the target platform according to the download verification information and the target download address. 
     Exemplarily, the access verification information may be a trusted root certificate list, and a trusted root certificate of the trusted root certificate list can be used to establish a trust chain to verify other certificates signed by the trusted root certificate. 
     When the vehicle downloads the access verification information in the target platform according to the download verification information and the target download address, the target platform can first perform authentication of the identity of the vehicle based on the download verification information of the vehicle. After the authentication is passed, the vehicle can download the access verification information in the target platform according to the target download address, so as to acquire the access verification information. 
     S 204 : communicate with a communication device in the target area according to the access verification information. 
     After acquiring the access verification information and the download verification information generated by the target platform for the vehicle, the vehicle has the trust chain of the target area at the same time. Therefore, the vehicle can communicate with the communication device in the target area according to the access verification information, thereby realizing the communication between the vehicle and the communication device in the target area. 
     It can be seen that in the embodiment of the present disclosure, when it is determined that a vehicle travels to a target area, determining a target platform corresponding to the target area and a target download address corresponding to the target platform according to a corresponding relationship between mutual trust platforms and areas, and download addresses corresponding to the mutual trust platforms; acquiring download verification information generated by the target platform for the vehicle; downloading access verification information in the target platform according to the download verification information and the target download address; and communicating with a communication device in the target area according to the access verification information, thereby realizing communication between the vehicle and the communication device in the target area. 
     Based on the first embodiment shown in  FIG. 2  above, exemplarily, in the embodiment of the present disclosure, when the vehicle sends the registration request message to the target platform to request the download verification information generated by the target platform for the vehicle through the registration request message, the response message may also include registration service interface addresses provided by the mutual trust platforms for the vehicle, so that the vehicle can first determine a registration service interface address provided by the target platform for the vehicle, and send the registration request message to the target platform based on the registration service interface address provided by the target platform for the vehicle, thereby improving a success rate of sending the registration request message. 
     Based on the first embodiment shown in  FIG. 2  above, it can be seen that in the embodiment of the present disclosure, it is precisely because that the vehicle acquires the corresponding relationship between the mutual trust platforms and the areas, and the download addresses corresponding to the mutual trust platforms, therefore, when it is determined that the vehicle travels to the target area, the target platform corresponding to the target area and the target download address corresponding to the target platform can be determined according to the corresponding relationship between the mutual trust platforms and the areas, and the download addresses corresponding to the mutual trust platforms, thereby realizing the communication between the vehicle and the communication device in the target area. Next, through the following second embodiment, how the vehicle acquires the corresponding relationship between the mutual trust platforms and the areas, and the download addresses corresponding to the mutual trust platforms in the embodiment of the present disclosure will be described in detail. 
     Embodiment 2 
       FIG. 3  is a schematic flowchart of a method for acquiring a corresponding relationship between mutual trust platforms and areas, and download addresses corresponding to the mutual trust platforms according to a second embodiment of the present disclosure. The method can also be executed by a software and/or a hardware apparatus, which may be a vehicle. As shown in  FIG. 3 , the method for acquiring the corresponding relationship between the mutual trust platforms and the areas, and the download addresses corresponding to the mutual trust platforms may include the following steps. 
     S 301 : send a request message to a global platform, where the request message includes registration verification information of the vehicle. 
     Exemplarily, the global platform can be seen in  FIG. 1 . Assuming that the global platform maintains the corresponding relationship between the mutual trust platforms and the areas, and the download addresses corresponding to the mutual trust platforms in the form of mutual trust platform list, the vehicle can send the request message to the global platform to acquire the mutual trust platform list from the global platform through the request message. 
     Exemplarily, in the embodiment of the present disclosure, each trusted mutual trust platform can report to the global platform the corresponding relationship between their mutual trust platform and a managed area, and a download address of access verification information corresponding to each mutual trust platform; after receiving the respective corresponding relationship reported by each mutual trust platform and the download address of the access verification information corresponding to each mutual trust platform, the global platform can build and save the mutual trust platform list based on the respective corresponding relationship and the download address of the access verification information corresponding to each mutual trust platform. 
     It should be noted that in the embodiment of the present disclosure, if each trusted mutual trust platform, in addition to reporting their respective corresponding relationship and the download address of the access verification information corresponding to each mutual trust platform, also reports to the global platform root verification information of their respective access verification information, a registration service interface address provided by each trusted mutual trust platform for the vehicle, and a name and a code of an area managed by each mutual trust platform. Correspondingly, the mutual trust platform list maintained in the global platform may also include the root verification information of the access verification information of each mutual trust platform, and the registration service interface address provided by each trusted mutual trust platform for the vehicle, and the name and code of the area managed by each mutual trust platform, which can be specifically set according to actual needs. 
     After the vehicle sends the request message including the registration verification information to the global platform, the global platform can verify an identity of the vehicle based on the registration verification information to determine whether the vehicle is a vehicle in a trustable area; if yes, the global platform sends a response message including a corresponding relationship between mutual trust platforms and areas, and download addresses corresponding to the mutual trust platforms to the vehicle. Correspondingly, the vehicle receives the response message sent by the global platform, that is, the vehicle executes the following S 302 . 
     S 302 : receive a response message sent by the global platform, where the response message includes the corresponding relationship between the mutual trust platforms and the areas, and the download addresses corresponding to the mutual trust platforms. 
     It can be seen that in the embodiment of the present disclosure, the vehicle can send the request message including the registration verification information to the global platform, and receive the corresponding relationship between the mutual trust platforms and the areas, and the download addresses corresponding to the mutual trust platforms sent by the global platform, so as to acquire the corresponding relationship between the mutual trust platforms and the areas, and the download addresses corresponding to the mutual trust platforms; in this way, the vehicle can determine a target platform corresponding to a target area and a target download address corresponding to the target platform according to the corresponding relationship between the mutual trust platforms and the areas, and the download addresses corresponding to the mutual trust platforms; and download access verification information in the target platform according to the target download address; consequently, the vehicle can communicate with a communication device in the target area according to the access verification information, thereby realizing communication between the vehicle and the communication device in the target area. 
     Based on the above embodiment shown in  FIG. 2  or  FIG. 3 , exemplarily, in the embodiment of the present disclosure, when the vehicle communicates with the communication device in the target area based on the access verification information, in order to ensure the security of the access verification information, the access verification information can be verified first. 
     Exemplarily, in the embodiment of the present disclosure, the mutual trust platform list acquired by the vehicle may also include root verification information of the access verification information of the trusted mutual trust platform. Taking the access verification information being a trusted root certificate list as an example, the root verification information of the access verification information may be a root certificate of the trusted root certificate list, in this way, when communicating with the communication device in the target area based on the access verification information, the vehicle can acquire the root verification information of the access verification information of the target platform from the mutual trust platform list, and the access verification information can be verified based on the root verification information; after the verification is successful, the vehicle can communicate with the communication device in the target area based on the access verification information, thereby realizing the communication between the vehicle and the communication device in the target area under the premise of ensuring the security of the access verification information. 
     Based on the above embodiment shown in  FIG. 2  or  FIG. 3 , exemplarily, in the embodiment of the present disclosure, when the vehicle communicates with the communication device in the target area based on the access verification information, taking the access verification information being the trusted root certificate list as an example, the trusted root certificate list may include a download address of a trusted domain certificate list corresponding to each trusted root certificate, in this way, the vehicle can first download the trusted domain certificate list corresponding to each trusted root certificate according to the download address of the trusted domain certificate list corresponding to each trusted root certificate; based on the trusted domain certificate list corresponding to each trusted root certificate, the vehicle can communicate with the communication device in the target area, thereby realizing the communication between the vehicle and the communication device in the target area. 
     Based on the above embodiment shown in  FIG. 2  or  FIG. 3 , exemplarily, in the embodiment of the present disclosure, when the vehicle communicates with the communication device in the target area, in order to avoid the leakage of the vehicle&#39;s real identity information and reduce the risk of privacy disclosure relating to a location of the vehicle, the vehicle can first acquire anonymous verification information from a verification management platform corresponding to the target area based on the download verification information generated by the target platform for the vehicle, and communicate with the communication device in the target area based on the anonymous verification information. Compared with the case where the vehicle communicates with the communication device in the target area based on a real certificate, the leakage of the vehicle&#39;s real identity information can be avoided, thereby reducing the risk of privacy disclosure relating to the location of the vehicle. 
     Exemplarily, when the vehicle acquires the anonymous verification information from the verification management platform corresponding to the target area based on the download verification information, it can directly acquire the anonymous verification information from the verification management platform corresponding to the target area based on the download verification information; or it can also first acquire a real certificate from the verification management platform corresponding to the target area based on the download verification information, and then acquire the anonymous verification information from the verification management platform corresponding to the target area based on the real certificate, which can be specifically set according to actual needs. 
     Exemplarily, in addition to the download verification information generated for the vehicle, the registration response message sent by the target platform to the vehicle may also include an interface address and platform verification information of the verification management platform corresponding to the target area. The platform verification information may be a certificate chain of an authority, so that the vehicle can first verify an identity of the verification management platform corresponding to the target area based on the platform verification information of the target area; and then acquire the anonymous verification information from the verification management platform according to the interface address of the verification management platform after the verification is successful, thereby improving the accuracy of the acquired anonymous verification information. 
     Exemplarily, the registration response message may also include interface addresses and certificate chains of other management authorities, such as an authentication and authorization (AAA), a pseudonym certificate registration authority (PRA), an application certificate registration authority (ARA), a misbehavior authority (MA) and a certificate revocation list authority (CRLA), which can be specifically set according to actual needs.

       FIG. 4  is a schematic flowchart of a communication method for a vehicle according to a third embodiment of the present disclosure. The communication method for the vehicle may also be executed by a software and/or a hardware apparatus, the hardware device may be a target platform. Exemplarily, as shown in  FIG. 4 , the communication method for the vehicle may include the following steps. 
     S 401 : receive a registration request message sent by the vehicle, where the registration request message includes registration verification information of the vehicle, and the registration request message is sent when the vehicle travels to a target area. 
     Exemplarily, the registration verification information may issue an initial security certificate for an area to which the vehicle belongs, such as an X509 certificate. The security certificate can prove an identity of the vehicle, and the area to which the vehicle belongs can be determined according to the security certificate. 
     When the vehicle travels to the target area, because the registration verification information issued by the area to which the vehicle belongs cannot be used as its pass certificate in the target area, in order to communicate with a communication device in the target area, it is necessary to send a registration request message including the registration verification information of the vehicle to a target platform to which the target area belongs, to enable the target platform to verify the identity of the vehicle based on the registration verification information of the vehicle, that is, the following S 402  is executed. 
     S 402 : verify the identity of the vehicle based on the registration verification information. 
     Exemplarily, when verifying the identity of the vehicle based on the registration verification information of the vehicle, if the verification of the identity of the vehicle fails, the target platform can send a registration failure response message to the vehicle; if the verification of the identity of the vehicle succeeds, after the verification is successful, the target platform generates download verification information in the target area for the vehicle, that is, executes the following S 403 . 
     S 403 : generate the download verification information of the vehicle after the verification is successful. 
     S 404 : send a registration response message to the vehicle, where the registration response message includes the download verification information, the download verification information is used for the vehicle to download access verification information from the target platform corresponding to the target area based on the download verification information and communicate with a communication device in the target area based on the access verification information. 
     It should be noted that in S 404 , for how the vehicle communicates with the communication device in the target area based on the download verification information and the access verification information downloaded from the target platform corresponding to the target area, reference can be made to description relating to the vehicle communicating with the communication device in the target area based on the download verification information and the access verification information downloaded from the target platform corresponding to the target area in the above embodiment shown in  FIG. 2 , details will not be repeated in the embodiment of the present disclosure. 
     It can be seen that in the embodiment of the present disclosure, a target platform receives a registration request message sent by a vehicle traveling to a target area, the registration request message including registration verification information of the vehicle, verifies an identity of the vehicle based on the registration verification information, generates download verification information of the vehicle after the verification is successful; and sends a registration response message including download verification information to the vehicle, to enable the vehicle to communicate with a communication device in the target area based on the download verification information and access verification information downloaded from the target platform corresponding to the target area, thereby realizing communication between the vehicle and the communication device in the target area. 
     Based on the embodiment shown in  FIG. 4  above, exemplarily, the registration response message may also include, in addition to the download verification information, an interface address and platform verification information of a verification management platform corresponding to the target area, and the platform verification information may be a certificate chain of an authority. It can be understood that in the embodiment shown in  FIG. 4 , the target platform sends the interface address and the platform verification information of the verification management platform corresponding to the target area to the vehicle through the registration response message, the implementation principle thereof is the same as the implementation principle of the receiving of the interface address and the platform verification information of the verification management platform corresponding to the target area sent by the target platform to the vehicle through the registration response message described on a vehicle side. For details, reference can be made to the relevant description on the vehicle side, details will not be repeated in the embodiment of the present disclosure. 
     Based on the above embodiment shown in  FIG. 4 , exemplarily, in the embodiment of the present disclosure, for any mutual trust platform, it can establish and register ecological partnerships with other mutual trust platforms in advance, record relevant information of all the ecological partnerships, and configure different verification strategies for different ecological partners. Therefore, when the target platform verifies the identity of the vehicle based on the download verification information, because the target platform has pre-stored download verification information of vehicles in its trusted trust area and verification strategies corresponding to different trust areas, the target platform can first determine whether the vehicle is a vehicle in the trusted trust area in the target area based on the download verification information; if not, the target platform feeds back the registration failure response message to the vehicle; if yes, the target platform verifies the identity of the vehicle based on the verification strategy corresponding to the area to which the vehicle belongs, thereby realizing the verification of the identity of the vehicle.

       FIG. 5  is a schematic flowchart of a communication method for a vehicle according to a fourth embodiment of the present disclosure. The communication method for the vehicle may also be executed by a software and/or a hardware apparatus, and the hardware apparatus may be a global platform. Exemplarily, as shown in  FIG. 5 , the communication method for the vehicle may include the following steps. 
     S 501 : receive a request message sent by the vehicle, where the request message includes registration verification information of the vehicle. 
     Since the global platform maintains a corresponding relationship between trusted mutual trust platforms and areas, and download addresses corresponding to the mutual trust platforms, when a vehicle in an area managed by any mutual trust platform travels to an area managed by another mutual trust platform, in order to communicate with a communication device in the area managed by said mutual trust platform, it is necessary to acquire a corresponding relationship between mutual trust platforms and areas, and download addresses corresponding to the mutual trust platforms from the global platform, and download access verification information based on the download address corresponding to the mutual trust platform, so as to communicate with the communication device in the area managed by the mutual trust platform based on the access verification information. 
     Exemplarily, when the vehicle acquires the corresponding relationship between the mutual trust platforms and the areas, and the download addresses corresponding to the mutual trust platforms from the global platform, it can send a request message including the registration verification information of the vehicle to the global platform. Correspondingly, after receiving the request message including the registration verification information of the vehicle, the global platform may verify an identity of the vehicle based on the registration verification information of the vehicle, that is, execute the following S 502 . 
     S 502 : verify the identity of the vehicle based on the registration verification information. 
     Exemplarily, when the global platform verifies the identity of the vehicle based on the registration verification information of the vehicle, if the verification of the identity of the vehicle fails, it can send a request failure response message to the vehicle; if the verification of the identity of the vehicle succeeds, after the verification is successful, it can send the corresponding relationship between the mutual trust platforms and the areas, and the download addresses corresponding to the mutual trust platforms to the vehicle through a response message, so that the vehicle can acquire the corresponding relationship between the mutual trust platforms and the areas, and the download addresses corresponding to the mutual trust platforms, that is, the global platform executes the following S 503 . 
     S 503 : send a response message to the vehicle after the verification is successful, where the response message includes the corresponding relationship between the mutual trust platforms and areas, and download addresses corresponding to the mutual trust platforms, the response message is used to instruct the vehicle to download the access verification information based on the corresponding relationship and the download addresses corresponding to the mutual trust platforms and communicate with a communication device in a target area based on the access verification information. 
     It can be understood that in the embodiment of the present disclosure, the global platform can maintain the corresponding relationship between the mutual trust platforms and the areas, and the download addresses corresponding to the mutual trust platforms through a mutual trust platform list, correspondingly, the vehicle acquires the mutual trust platform list from the global platform; the global platform can also maintain the corresponding relationship between the mutual trust platforms and the areas, and the download addresses corresponding to the mutual trust platforms in a form of mutual trust platform list; or the corresponding relationship between the mutual trust platforms and the areas, and the download addresses corresponding to the mutual trust platforms can also be maintained in other ways, which can be specifically set according to actual needs. 
     Taking maintaining the corresponding relationship between the mutual trust platforms and the areas, and the download addresses corresponding to the mutual trust platforms through the mutual trust platform list as an example, in addition to the corresponding relationship between the mutual trust platforms and the areas, and the download addresses corresponding to the mutual trust platforms, the mutual trust platform list may also include the root certificate of the trusted root certificate list authority of each mutual trust platform, an registration service interface address provided by each trusted mutual trust platform for the vehicle, and a name and a code of an area managed by each mutual trust platform and so on, which can be specifically set according to actual needs. 
     It should be noted that in S 504 , for how the vehicle communicates with the communication device in the target area based on the download verification information and the access verification information downloaded from the target platform corresponding to the target area, reference can be made to description relating to the vehicle communicating with the communication device in the target area based on the download verification information and the access verification information downloaded from the target platform corresponding to the target area in the above embodiment shown in  FIG. 2 , details will not be repeated in the embodiment of the present disclosure. 
     It can be seen that in the embodiment of the present disclosure, a global platform receives a request message sent by a vehicle traveling to a target area, the request message including registration verification information of the vehicle, verifies an identity of the vehicle based on the registration verification information, and sends a corresponding relationship between mutual trust platforms and areas, and download addresses corresponding to the mutual trust platforms to the vehicle through a response message after the verification is successful, so that the vehicle can download access verification information based on the corresponding relationship and the download addresses corresponding to the mutual trust platforms, and communicate with a communication device in the target area based on the access verification information, thereby realizing communication between the vehicle and the communication device in the target area. 
     Based on the above embodiment shown in  FIG. 5 , assuming that the global platform maintains the corresponding relationship between the mutual trust platforms and the areas, and the download addresses corresponding to the mutual trust platforms in the form of mutual trust platform list, the global platform needs to build the mutual trust platform list before sending the mutual trust platform list to the vehicle through the response message. Exemplarily, when the global platform builds the mutual trust platform list, the global platform can receive a corresponding relationship between a mutual trust platform and a managed area reported by each trusted mutual trust platform, and an download address of access verification information corresponding to each mutual trust platform; and builds the mutual trust platform list according to the corresponding relationship and the download address of the access verification information corresponding to each mutual trust platform. 
     It should be noted that in the embodiment of the present disclosure, if each trusted mutual trust platform, in addition to reporting their respective corresponding relationship and the download address of the access verification information corresponding to each mutual trust platform, also reports root verification information of their respective access verification information, a registration service interface address provided by each trusted mutual trust platform for the vehicle, and a name and a code of an area managed by each mutual trust platform to the global platform. Correspondingly, the mutual trust platform list maintained in the global platform may also include the root verification information of the access verification information of each mutual trust platform, and the registration service interface address provided by each trusted mutual trust platform for the vehicle, and the name and the code of the area managed by each mutual trust platform, which can be specifically set according to actual needs. 
     It can be understood that information of a trusted mutual trust platform may change, for example, the download address corresponding to the mutual trust platform may change. Therefore, the global platform may update the mutual trust platform list based on the download address corresponding to the changed mutual trust platform, and in order to ensure that the vehicle can acquire the latest mutual trust platform list, the vehicle can regularly download and acquire the mutual trust platform list from the global platform, so as to acquire the latest corresponding relationship between the mutual trust platforms and the areas, and the download addresses corresponding to the mutual trust platforms. 
     Embodiment 5 
     In order to describe the technical solution provided by the embodiment of the present disclosure, an example is taken where a corresponding relationship between mutual trust platforms and areas, and download addresses corresponding to the mutual trust platforms is maintained through a mutual trust platform list, download verification information is a target security certificate, and access verification information is a trusted root certificate list.  FIG. 6  is a schematic flowchart of a communication method for a vehicle according to a fifth embodiment of the present disclosure. The communication method for the vehicle may also be executed by a software and/or a hardware apparatus, and the hardware apparatus may be applied to a communication system. Exemplarily, as shown in  FIG. 6 , the communication method for the vehicle may include the following steps. 
     S 601 : the vehicle downloads and acquires the mutual trust platform list from a global platform, where the mutual trust platform list includes the corresponding relationship between trusted mutual trust platforms and areas, and download addresses corresponding to the mutual trust platforms. 
     It should be noted that when implementing the technical solution of the present disclosure, it is not necessary to implement S 601  first. If the mutual trust platform list has been saved locally in the vehicle when the technical solution of the present disclosure is implemented, S 602  can be executed directly to determine a target platform to which a target area belongs and the download address corresponding to the target platform from the mutual trust platform list; on the contrary, if the mutual trust platform list is not saved locally in the vehicle when the technical solution of the present disclosure is implemented, the mutual trust platform list can be downloaded and acquired from the global platform first, and then S 602  can be executed, that is, the target platform to which the target area belongs and the download address corresponding to the target platform can be determined from the mutual trust platform list. 
     S 602 : when the vehicle travels to the target area, determine the target platform to which the target area belongs and the download address corresponding to the target platform from the mutual trust platform list. 
     S 603 : the vehicle sends a registration request message to the target platform, where the registration request message includes a security certificate issued by an area to which the vehicle belongs. 
     S 604 : after verification of an identity of the vehicle is successful, the target platform generates for the vehicle the target security certificate for travelling in the target area, and sends a registration response message including the target security certificate to the vehicle. 
     S 603  and S 604  are mainly used to acquire the target security certificate generated by the target platform for the vehicle. It should be noted that when the vehicle acquires the target security certificate generated by the target platform for the vehicle, if the vehicle travels to the target area for the first time, it can send the registration request message to the target platform and receive the registration response message to acquire the target security certificate; if the vehicle travels to the target area again within a valid period of use, the vehicle can directly acquire the target security certificate locally (from the vehicle itself) without sending the registration request message to the target platform to request the target security certificate generated by the target platform for the vehicle, thus preventing the vehicle from interacting with the target platform again, thereby improving efficiency of acquiring the target security certificate. 
     S 605 : the vehicle downloads a trusted root certificate list of the target platform according to the target security certificate and the download address. 
     S 606 : the vehicle communicates with a communication device in the target area based on the trusted root certificate list. 
     It can be seen that in the embodiment of the present disclosure, since a mutual trust platform list includes a corresponding relationship between mutual trust platforms and areas, and download addresses corresponding to mutual trust platforms, when travelling to a target area, a vehicle can determine a target platform and a download address corresponding to the target platform from the mutual trust platform list, download a trusted root certificate list of the target platform based on a target security certificate and the download address generated by the target platform for the vehicle, and then communicate with the communication device in the target area based on the trusted root certificate list, thereby realizing communication between the vehicle and the communication device in the target area.
