[0024] Embodiment 1

[0025] Figure 1This is a schematic diagram of the structure of a vehicle review system provided by an embodiment of the present invention. This embodiment can be applied to the situation of reviewing a vehicle. The vehicle review system can be applied to the vehicle review method. The vehicle review system can be implemented in the form of hardware and / or software. Figure 1 As shown, the vehicle review system may include: a vehicle information security management and control module 110 and a vehicle synchronization engineering module 120 .

[0026] The vehicle information security control module 110 is used to call the target vehicle ciphertext of the target vehicle from the information storage database, decrypt the target vehicle ciphertext of the target vehicle to obtain the target vehicle information, and encrypt the target vehicle information with the target session key to obtain the target review information of the target vehicle and send it to the vehicle synchronization engineering module;

[0027] The automobile synchronization engineering module 120 is used to receive the target review information of the target vehicle sent by the vehicle information security control module, decrypt the target review information using the communication component to obtain the target vehicle information of the target vehicle, and review the target vehicle according to the target vehicle information to obtain the review result of the target vehicle;

[0028] Among them, the information storage database is used to store the vehicle ciphertext of different vehicles obtained by encrypting the vehicle information of different vehicles received by the vehicle information security management and control module using the first encryption method, and the vehicle information is the review information of vehicles that need to undergo vehicle review; the target session key is constructed by a temporary key generated by the automobile synchronization engineering module using the communication component, and the communication component has a component for establishing a communication connection between the vehicle information security management and control module and the automobile synchronization engineering module.

[0029] Among them, the first encryption method can be a method of encryption using a PCI-e cryptographic card. The PCI-e cryptographic card integrates a new cryptographic algorithm (SM1, SM2, SM3, SM4, etc.). The communication component can be an SDK component. The vehicle information security management module and the vehicle synchronization engineering module follow the TLS communication protocol.

[0030] Optionally, in order to ensure that the target vehicle is reviewed and to ensure that the vehicle information can be safely transmitted from the vehicle information security control module to the automobile synchronization engineering module, before receiving the target review information of the target vehicle sent by the vehicle information security control module, the automobile synchronization engineering module sends the second communication certificate of the target vehicle to the vehicle information security control module. The vehicle information security control module uses the first communication certificate of the target vehicle to compare and verify the second communication certificate to determine that the identity authentication of the target vehicle is successful.

[0031] Optional, such as Figure 2 As shown, the automobile synchronous engineering module includes a synchronous engineering configuration unit 1201 and a review unit 1202:

[0032] The synchronous engineering configuration unit 1201 is used to receive the target review information of the target vehicle sent by the vehicle information security control module, and decrypt the target review information using the communication component to obtain the target vehicle information of the target vehicle;

[0033] The review unit 1202 is used to review the target vehicle based on the target vehicle information and adopt the review model to obtain the review result of the target vehicle, and send the review result of the target vehicle to the vehicle information security management and control module. The review model may include but is not limited to a consistency review model, an electrical function design solution review model, a diagnosis review model, a historical fault library review model, and an information security review model.

[0034] Specifically, Figure 2 As shown, the vehicle information security control module includes a vehicle information management unit 1101 and a communication unit 1102. When conducting a vehicle review, the vehicle information management unit 1101 calls the target vehicle ciphertext of the target vehicle from the information storage database, decrypts the target vehicle ciphertext of the target vehicle to obtain the target vehicle information, and then the vehicle information management unit 1101 receives the target session key constructed by the temporary key generated by the communication component and sent by the automobile synchronization engineering module, encrypts the target vehicle information with the target session key to obtain the target review information of the target vehicle, and then sends the target review information to the automobile synchronization engineering module, so that the automobile synchronization engineering module can review the target vehicle.

[0035] Optionally, before reviewing a vehicle, the vehicle review system needs to perform preliminary preparations, specifically:

[0036] The vehicle information security management and control module includes a vehicle information management unit 1101 and a communication unit 1102;

[0037] The vehicle information management unit 1101 is used to verify the received vehicle information of different vehicles. After the verification is passed, the vehicle information of different vehicles is encrypted using a first encryption method to obtain vehicle ciphertexts of different vehicles, and the vehicle ciphertexts are stored in the information storage database.

[0038] Specifically, the vehicle information received from different vehicles is verified, including: obtaining reference verification information of a reference vehicle, and determining whether the vehicle information of the reference vehicle has passed the verification based on the comparison between the reference verification information and preset verification information; the verification information includes at least the vehicle VIN code and the vehicle controller SN number.

[0039] The communication unit 1102 is used to generate a communication component suitable for the automobile synchronous engineering module in response to the communication component activation application sent by the automobile synchronous engineering module, and send the communication component to the automobile synchronous engineering module.

[0040] Specifically, after the communication component is sent to the automobile synchronization engineering module, the automobile synchronization engineering module matches the communication component with the internal information of the automobile synchronization engineering module so that the communication component is activated in the automobile synchronization engineering module, thereby establishing data security transmission between the vehicle information security management and control module and the automobile synchronization engineering module.

[0041] Optionally, after the communication component is activated in the automobile synchronization engineering module, the communication unit of the vehicle information security management and control module is used to respond to communication certificate application requests for different vehicles sent by the automobile synchronization engineering module to the vehicle information security management and control module, generate second communication certificates for different vehicles based on the first communication certificates of different vehicles, and send the second communication certificate to the automobile synchronization engineering module to facilitate the subsequent verification of the vehicle identity when conducting a vehicle review. The communication certificate is used to authenticate the identity of the vehicle.

[0042] The technical solution of the embodiment of the present invention includes a vehicle information security control module and an automobile synchronization engineering module. The vehicle information security control module is used to call the target vehicle ciphertext of the target vehicle from the information storage database, decrypt the target vehicle ciphertext of the target vehicle to obtain the target vehicle information, and send the target vehicle target review information obtained by encrypting the target vehicle information with a target session key to the automobile synchronization engineering module; the automobile synchronization engineering module is used to receive the target review information of the target vehicle sent by the vehicle information security control module, decrypt the target review information with a communication component to obtain the target vehicle information of the target vehicle, and review the target vehicle according to the target vehicle information to obtain the review result of the target vehicle. The present invention encrypts the vehicle information through the vehicle information security control module to ensure the security of the vehicle information. The vehicle information security control module and the automobile synchronization engineering module are combined to review the vehicle, thereby improving the efficiency of the vehicle review.

[0043] Embodiment 2

[0044] The technical solution of this embodiment further describes the vehicle review system of the aforementioned embodiment in detail on the basis of the aforementioned embodiment. This embodiment can be combined with various optional solutions in one or more of the aforementioned embodiments.

[0045] like Figure 2As shown, the vehicle review system includes a vehicle information security management and control module and an automobile synchronous engineering module. The vehicle information security management and control module includes a vehicle information management unit and a communication unit. The communication unit includes a communication certificate generation unit and a communication component generation unit. The automobile synchronous engineering module includes a synchronous engineering configuration unit, a review unit, a communication certificate storage unit and a communication component.

[0046] In order to ensure the information security in the automobile synchronous engineering module, the present invention builds a vehicle review system based on the vehicle information security management and control module and the automobile synchronous engineering module. Before the vehicle review system conducts a vehicle review, processes such as vehicle data storage, certificate issuance, and component function activation are required, namely, the vehicle review preparation stage. Figure 3 This is a flow chart of a vehicle review preparation stage provided by an embodiment of the present invention. The specific process is as follows:

[0047] Information storage database:

[0048] 1) During the review preparation stage, once the vehicle meets the review conditions, the vehicle will upload its basic information to the vehicle information security management and control module to manage the vehicle information and store files.

[0049] 2) The person in charge of the relevant vehicle shall investigate and organize the basic information of the vehicle and generate the vehicle information for the review of the vehicle synchronization project.

[0050] 3) The vehicle information management unit conducts an initial review of the vehicle information obtained from the vehicle information source. Specifically, the review process is: the vehicle information management unit verifies whether the vehicle VIN code, vehicle controller SN number and other information are legal.

[0051] 4) After the vehicle information management unit verifies that the basic information of the vehicle is legal, it calls the PCI-e password card to generate the key, and uses the password card to encrypt the vehicle information, and stores the basic information such as the vehicle information in the form of ciphertext in the information storage database. Among them, the PCI-e password card integrates new cryptographic algorithms (SM1, SM2, SM3, SM4, etc.).

[0052] 5) If the vehicle information management unit confirms that the vehicle information is in an illegal state, it will feedback the illegal information to the vehicle information source, and the relevant person in charge will confirm the vehicle information and re-upload the vehicle information for vehicle review.

[0053] The communication component in the automotive synchronous engineering module is activated. The communication component is an SDK component:

[0054] 6) The vehicle synchronization engineering module needs to establish a connection with the vehicle information security management and control module and receive vehicle information. The vehicle synchronization engineering module generates a communication SDK component application and obtains the SDK component to establish a communication link.

[0055] 7) The vehicle information security management and control module reviews the received SDK component application request, reviews the address of the vehicle synchronization engineering module and other related information, and verifies the key fields in the request.

[0056] 8) The vehicle information management unit confirms the legitimacy of the request and the legitimacy of the system. The communication component generation unit in the communication unit generates a security SDK component used by the vehicle synchronization engineering module. The SDK component needs to be activated in the vehicle synchronization engineering module. It has the basic function of establishing TLS communication between systems, and can realize certificate authentication, temporary key generation, session key construction, data encryption and decryption and other functions. It is responsible for the encrypted transmission of data between systems. Commonly used commercial cryptographic algorithms are applied in the process of data transmission: DES, RSA, MD5 and other encryption algorithms.

[0057] 9) The vehicle information management unit can feed back illegal SDK requests to the vehicle synchronization engineering module. After the vehicle synchronization engineering module investigates the cause of the problem internally, it confirms whether to make a second application.

[0058] 10) The vehicle information management unit sends the generated SDK component in plain text to the vehicle synchronous engineering module. Since the SDK component has system compatibility, the plain text transmission of the SDK component does not affect the subsequent encrypted transmission of data.

[0059] 11) The vehicle synchronization engineering module receives the security SDK component sent by the vehicle information security management and control module. Its internal system information can be matched with the SDK component, so the component is activated and the component function can be used normally.

[0060] 12) The automobile synchronization engineering module successfully activates the SDK component issued by the vehicle information security management module. It needs to apply to the vehicle information security management module for the communication certificate required for identity authentication in communication. It generates a communication certificate application request internally and uploads it to the vehicle information security management module.

[0061] 13) The vehicle information security management and control module receives the certificate application request and calls the internal communication certificate generation unit to apply for the communication certificate. The communication certificate generation unit supports the standard PKI architecture. It can independently issue digital certificates for other module users through the built-in CA module, and can authenticate certificates issued by third-party CA by importing CA root certificate + CRL list. This communication certificate generation unit issues digital certificates for the vehicle synchronization engineering module through the built-in CA.

[0062] 14) The vehicle information security management and control module sends the communication certificate to the vehicle synchronization engineering module through the preset temporary certificate.

[0063] 15) The vehicle synchronous engineering module verifies the validity of the certificate internally, that is, verifies whether the certificate can achieve two-way identity authentication with the vehicle information security management and control module.

[0064] 16) After the vehicle synchronization engineering module verifies that the certificate is valid and can perform two-way identity authentication with the vehicle information security control module, the certificate is stored internally in the communication certificate storage unit for identity authentication and system authority control during system use. The validity period of the certificate storage is one year, which further ensures the security of the certificate and the reliability of identity authentication.

[0065] The vehicle review conducted by the vehicle review system of the present invention requires the vehicle synchronization engineering module to obtain target vehicle information from the vehicle information security management and control module, and then use the review unit of the vehicle synchronization engineering module to complete the vehicle review. Figure 4 This is a flow chart of a vehicle review stage provided by an embodiment of the present invention. The specific process is as follows:

[0066] 1) During the vehicle review phase, identify the target vehicles that need to be reviewed using the vehicle review system.

[0067] 2) The vehicle synchronization engineering module calls the internally stored communication certificate to authenticate the identity with the vehicle information security management and control module, exchanges the communication certificate with the vehicle information security management and control module, and verifies the legitimacy of each other's identities.

[0068] 3) If the identity authentication fails, the vehicle information security management module will record the log and issue a system warning, alert the illegal system to access the information storage database, and feedback the identity authentication failure information.

[0069] 4) The vehicle synchronization engineering module conducts an internal audit based on the identity authentication failure information to confirm whether the communication certificate is abnormal or the system has uploaded incorrect basic information.

[0070] 5) After the identity authentication is passed, the vehicle information security management and control module generates a temporary key and issues it. The automobile synchronization engineering module calls the SDK component to generate a temporary key and then builds the key to build the target session key to realize data interaction.

[0071] 6) The vehicle information security management and control module uses a password card to decrypt the target vehicle information stored in the information storage database, and encrypts it with the target session key and sends it to the vehicle synchronization engineering module. The vehicle information security management and control module and the vehicle synchronization engineering module follow the TLS communication protocol, and a secure TLS encryption link is established between the modules.

[0072] 7) The synchronous engineering system application obtains the ciphertext of the vehicle input file, and then calls the SDK component to decrypt the ciphertext, verifies the integrity of the data through the random number carried in the data transmission, and then imports the vehicle information into the internal review module for vehicle review.

[0073] 8) The review unit of the automotive synchronous engineering module automatically reviews the vehicle input files through the consistency review model, electrical function design review model, diagnosis review model, historical fault library review model, and information security review model, and outputs an automatic review report based on the automatic review algorithm preset within the automotive synchronous engineering module.

[0074] 9) The automobile synchronous engineering module binds the target vehicle information with the review report and uploads it to the vehicle information security management module. On the one hand, the vehicle review results cached in the automobile synchronous engineering module can be directly viewed, and the review report of the relevant vehicle can be obtained from the vehicle information security management module, thus realizing the system management of vehicle reviews and improving the traceability of the review process.

[0075] The technical solution of the embodiment of the present invention adopts PCI-e password card for hardware encryption to ensure the security of vehicle information storage; symmetric key encryption algorithms such as 3DES are used to encrypt data during data transmission, and public key encryption algorithms such as RSA are used to exchange keys and certificates, which ensures the integrity of data and prevents it from being illegally stolen; in the interactive process, two-way identity authentication is performed through preset certificates and installed components, which ensures the use rights of the system and reduces the system security risks caused by user-level threats. In addition, the vehicle synchronization engineering module receives the vehicle information called from the vehicle information security management and control module, and conducts vehicle review, which ensures the security of vehicle information and improves the efficiency of vehicle review.
