The OBU supports GBA network security capability, bidirectional identity authentication is realized between the OBU and a network (namely a core network), a session key is negotiated, and a secure channel is provided for downloading the electronic license plate, so that the electronic license plate is safely downloaded and stored in the SIM.

In the embodiment of the application, the electronic license plate is safely downloaded based on a mobile communication network; specifically, after the vehicle owner selects the license plate number, the vehicle owner registers the vehicle owner information, the vehicle identification code, the SIM information of the OBU, the license plate number and other information in the electronic license plate management platform, the license plate management platform generates a corresponding electronic license plate by using the information, and establishes a corresponding relation between the SIM information and the electronic license plate. After the OBU is started, a secure communication channel is established between the OBU and the electronic license plate management platform by using the GBA capability of the network, so that the electronic license plate is safely downloaded to an SIM (subscriber identity module) of the OBU and is stored in a security domain of the SIM.

Here, with reference to fig. 8, the process of securely downloading the electronic license plate based on the mobile communication network specifically includes:

step 1: when the vehicle leaves a factory, an electronic license plate application (used for storing the electronic license plate to the SIM, reading the electronic license plate from the SIM and the like) is preset in the SIM of the OBU. The vehicle owner fills basic information of a vehicle user in the electronic license plate management platform, wherein the basic information comprises information such as vehicle owner information, a vehicle identification code number (frame number), SIM (subscriber identity module) information, a motor vehicle license plate and the like, and the electronic license plate management platform generates a corresponding electronic license plate according to the information and establishes a corresponding relation between the SIM information and the electronic license plate;

Here, during practical application, a function key can be set on the OBU, and after the OBU is started, the function key is operated to enable one key to initiate application of downloading the electronic license plate from the electronic license plate management platform.

And step 3: the electronic license plate management platform accesses a GBA service platform to acquire a GBA session key of the OBU;

and 4, step 4: the OBU and the electronic license plate management platform establish a secure channel, namely, a symmetric key (GBA session key) is adopted for encryption transmission, and the electronic license plate is safely downloaded to the OBU through the established secure channel and stored in the SIM.

In the above process, the communication module of the OBU interacts with the electronic license plate management platform.

In practical application, when the electronic license plate is valid for a period (namely, after the electronic license plate is expired), the electronic license plate is updated by adopting the method.

After the electronic license plate is stored to the security domain of the SIM, the electronic license plate can be identified based on the cellular network.

The OBU has V2X communication capability, can realize the vehicle to V2I and V2N, V2V, V2P altogether 4 kinds of V2X applications. And the identification of the electronic license plate of the vehicle can be realized based on the V2X communication capability of the OBU.

The first mode is that the electronic license plate is identified based on the PC5 direct communication mode

Specifically, through the V2X communication technology, the OBU broadcasts the BSM, including location information, speed, direction, etc. related information of the vehicle, to the surrounding vehicles and RSUs at a frequency of up to 10Hz through the PC5 interface. In this application embodiment, in order to realize the identification of the electronic license plate, fields may be added to the BSM information to indicate the electronic license plate, specifically as shown in fig. 2, that is, VDIindicator and VDI fields are added to the BSM field to indicate the electronic license plate of the vehicle:

BasicSafetyMessage::＝SEQUENCE{

……

VDIindicator VDIindicator,

- -0: no VDI field, 1: having a VDI field

VDI VehicleDigitalIdentity OPTIONAL

- -electronic license plate

……

}

When the vehicle normally runs, the VDI is not sent, the VDIindicator of the BSM is 0, and the BSM message does not carry the VDI information; when a vehicle passes through an intersection provided with an RSU, a VDI is sent, a VDIindicator of a BSM is 1, and a BSM message carries VDI information.

As shown in fig. 9, the basic flow of electronic license plate recognition based on PC5 direct communication includes:

step 2: BSM is broadcasted, in order to save the operation resources of OBU and RSU, VDI field of electronic license plate is broadcasted with frequency lower than 10Hz, such as 1 Hz;

and step 3: after the RSU receives the BSM, security authentication is carried out, the correctness of the certificate and the signature is verified, and after the verification is successful, the V2X coding and decoding module of the RSU analyzes the information such as the electronic license plate, the vehicle position and the like from the BSM. The RSU automatically completes the recognition of the electronic license plate of the vehicle without contact and stop.

As shown in fig. 10, a specific flow of electronic license plate recognition based on PC5 direct communication includes:

step 1001: the V2X message coding and decoding module of the OBU requests the SIM for the electronic license plate;

step 1002: after receiving the request, the SIM returns the electronic license plate to the V2X message encoding and decoding module;

step 1003: the V2X message coding and decoding module generates a V2X message Body (BSM) by using an electronic license plate and the like;

step 1004: the V2X message coding and decoding module requests a signature from the security operation module;

step 1005: after receiving the request, the security operation module of the OBU carries out digital signature on the V2X message body;

step 1006: the safety operation module returns a response to the V2X message encoding and decoding module; responding to the V2X message body carrying the digital signature and the security certificate;

step 1007: the V2X message encoding and decoding module sends the received digitally signed V2X message body and the security certificate to the PC5 communication module of the OBU;

step 1008: transmitting a V2X broadcast message through the PC5 communication module; namely broadcasting the signed V2X message body and security certificate;

step 1009: after receiving the message through the PC5 communication module, the RSU sends the signed V2X message body and the security certificate to a V2X message coding and decoding module of the RSU;

step 1010: the V2X message encoding and decoding module sends the signed V2X message body and the security certificate to a security module of the RSU to request for verification;

step 1011: the safety module verifies the certificate and the signature to obtain a verification result, and a V2X message body is obtained after the verification is successful;

step 1012: the security module sends the obtained V2X message body to a V2X message coding and decoding module;

step 1013: the V2X message encoding and decoding module analyzes the V2X message body to obtain an electronic license plate, so as to perform subsequent operations, such as reporting to an electronic license plate management platform.

The second mode is that the electronic license plate is identified based on the Uu interface

The electronic license plate is identified based on the Uu interface: through the mobile network communication capability of the Uu interface, the electronic license plate management system can initiate an instruction of electronic license plate inspection to monitor the vehicle.

Specifically, as shown in fig. 11, the process of identifying the electronic license plate based on the Uu interface includes:

step 1: the electronic license plate management platform sends an electronic license plate checking request to the OBU;

step 2: the OBU calls the GBA network security capability, based on a 4G/5G network root key stored in the SIM, the OBU and the network perform bidirectional identity authentication and key agreement through the GBA network security capability, and the GBA service platform generates a GBA session key; the electronic license plate management platform accesses the GBA service platform to acquire a GBA session key so as to establish a secure channel between the OBU and the electronic license plate platform;

and 3, step 3: the OBU acquires the electronic license plate and BSM message codes in the SIM, carries out signature, attaches a security certificate and the like, and sends the signature to the electronic license plate management platform through a Uu interface to check the electronic license plate.
