Description

Technical Field

[0001] The present invention relates to the technical field of quantum security and intelligent networked vehicles, and in particular to a data protection system and method for intelligent networked vehicles based on quantum security. Background Art

[0002] Intelligent connected vehicles integrate modern communication and network technologies, and can achieve wireless communication and information exchange between vehicles, roads, pedestrians, business platforms, etc.

[0003] At present, the data confidentiality communication technology of intelligent networked vehicles is based on the transport layer security protocol, but there are many private data stored inside the intelligent networked vehicles, such as voice data, biometric authentication information, video acquisition data, etc. These private data cannot be stored confidentially through the transport layer security protocol, and additional data encryption and decryption modules need to be developed for protection. In addition, keys generated by other methods are also required, such as generating encryption keys through basic feature values ​​(such as vehicle product serial number, vehicle identification code), but these basic feature values ​​can be queried or known, and there is a possibility of being cracked.

[0004] Intelligent network and unmanned systems are the key applications and demonstrations of quantum technology in the future industry. It is reported that with the rapid development of quantum computing technology, third parties can crack these algorithms in polynomial time through quantum computers, which may pose a serious threat and interference to the sensitive data of intelligent networked vehicles (such as vehicle spatiotemporal information, owner identity information, etc.).

[0005] Therefore, the data security of existing intelligent connected vehicles is not high enough, and cannot simultaneously take into account the security protection of network communications and internal data storage. Summary of the invention

[0006] In order to solve the problem that the data security of existing intelligent connected vehicles is not high enough, the present invention provides a data protection system and method for intelligent connected vehicles based on quantum security.

[0007] To achieve the above purpose, the technical solution adopted by the present invention is as follows:

[0008] A quantum-safe intelligent connected vehicle data protection system, including a vehicle side and a cloud side;

[0009] The vehicle end includes an intelligent cockpit module, a vehicle end security protection module and a quantum security module;

[0010] The cloud includes a cloud server, a cloud security protection module and a quantum key resource server;

[0011] When the smart cockpit module on the vehicle side is connected to the cloud server, quantum information identity authentication is performed. The steps are as follows:

[0012] The vehicle-side security guard module calls the quantum security module to use the pre-assigned quantum key to encrypt the identity authentication request and send it to the cloud server; the cloud-side security guard module intercepts the identity authentication request ciphertext sent to the cloud server and forwards it to the quantum key resource server; the quantum key resource server obtains the corresponding quantum key to decrypt the identity authentication request and returns the decrypted identity authentication request plaintext to the cloud security guard module; the cloud security guard module forwards the identity authentication request plaintext to the cloud server for identity authentication; when the cloud server completes the verification and sends a response, the cloud security guard module intercepts and encrypts the response and sends it to the smart cockpit module; the vehicle-side security guard module intercepts the response ciphertext sent to the smart cockpit module, and calls the quantum security module to use the pre-assigned quantum key to decrypt it, and forwards the response plaintext to the smart cockpit module after obtaining it; based on the decrypted response plaintext, it is determined whether the quantum information identity authentication is passed; if passed, the smart cockpit module performs quantum encryption communication with the cloud server; if not, the quantum information identity authentication is performed again.

[0013] In the above solution, by deploying security protection modules on the vehicle side and in the cloud to automatically intercept network communication data, and using quantum keys to encrypt and decrypt network communication data, efficient and secure communication is achieved, which comprehensively improves the security of smart connected vehicle data and prevents it from being cracked by quantum computing, while not affecting the network communication experience of smart connected vehicles.

[0014] Preferably, when the smart cockpit module initiates a storage / reading instruction,

[0015] The vehicle-side security protection module automatically intercepts the underlying file interface, reads the corresponding data, calls the quantum security module to encrypt / decrypt the data using the pre-assigned quantum key, and returns the encrypted / decrypted data to the smart cockpit module for storage / reading.

[0016] In the above scheme, the underlying network communication and file operation interface of the smart cockpit module are automatically intercepted through the vehicle-side security protection module, which can not only encrypt and decrypt the application layer network communication, but also effectively protect the internal files of the smart cockpit module, thereby realizing the comprehensive protection of the data of smart connected vehicles and facilitating unified and controlled access to the privacy data of smart connected vehicles.

[0017] Preferably, the vehicle end further includes a privacy configuration module;

[0018] When the smart cockpit module initiates a storage instruction, the vehicle-side security guard module automatically intercepts the underlying file interface, reads the data to be stored and the privacy configuration preset in the privacy configuration module, calls the quantum security module according to the preset privacy configuration to use the pre-assigned quantum key to selectively encrypt the data to be stored, and returns the encrypted data to the smart cockpit module for storage;

[0019] When the smart cockpit module initiates a read command, the vehicle-side security guard module automatically intercepts the underlying file interface, reads the corresponding encrypted data and the privacy configuration preset in the privacy configuration module, and calls the quantum security module to use the pre-assigned quantum key to decrypt the data according to the preset privacy configuration, and returns the decrypted data to the smart cockpit module for reading.

[0020] In the above scheme, by presetting the privacy configuration in the privacy configuration module, the non-privacy data that is unnecessary to be encrypted is filtered, the performance pressure caused by the encryption and decryption operations is reduced, and the data processing speed is improved.

[0021] Preferably, the data types of the privacy configuration include vehicle spatiotemporal information, driving monitoring data, biometric collection information, voice collection information, camera image data and lidar data.

[0022] Preferably, the quantum key resource server obtains the corresponding quantum key according to the uuid of the identity authentication request ciphertext to decrypt the identity authentication request.

[0023] Preferably, the response types issued by the cloud server upon completion of verification include success, failure, no response and invalid request.

[0024] A quantum-safe intelligent connected vehicle data protection method is implemented based on the quantum-safe intelligent connected vehicle data protection system. When the intelligent cockpit module on the vehicle side is connected to the cloud server, the following quantum information identity authentication steps are performed:

[0025] S1: The vehicle-side security guard module calls the quantum security module to use the pre-assigned quantum key to encrypt the identity authentication request and send it to the cloud server;

[0026] S2: The cloud security guard module intercepts the identity authentication request ciphertext sent to the cloud server and forwards it to the quantum key resource server;

[0027] S3: The quantum key resource server obtains the corresponding quantum key to decrypt the identity authentication request ciphertext, and returns the decrypted identity authentication request plaintext to the cloud security guard module;

[0028] S4: The cloud security guard module forwards the identity authentication request in plain text to the cloud server for identity authentication;

[0029] S5: When the cloud server completes the verification and sends a response, the cloud security guard module intercepts and encrypts the response and sends it to the smart cockpit module;

[0030] S6: The vehicle-side security guard module intercepts the response ciphertext sent to the smart cockpit module, calls the quantum security module to decrypt it using the pre-assigned quantum key, and forwards the response plaintext to the smart cockpit module after obtaining it;

[0031] S7: judging whether the quantum information identity authentication is successful according to the response plaintext obtained by decryption;

[0032] If it passes, the smart cockpit module will conduct quantum encrypted communication with the cloud server;

[0033] If it fails, return to step S1 and perform quantum information identity authentication again.

[0034] Preferably, when the smart cockpit module initiates a storage / reading instruction, the following internal data processing steps are performed:

[0035] The vehicle-side security protection module automatically intercepts the underlying file interface, reads the corresponding data, calls the quantum security module to encrypt / decrypt the data using the pre-assigned quantum key, and returns the encrypted / decrypted data to the smart cockpit module for storage / reading.

[0036] Preferably, the internal data processing steps are specifically as follows:

[0037] When the smart cockpit module initiates a storage instruction, the vehicle-side security guard module automatically intercepts the underlying file interface, reads the data to be stored and the preset privacy configuration, calls the quantum security module according to the preset privacy configuration, uses the pre-assigned quantum key to selectively encrypt the data to be stored, and returns the encrypted data to the smart cockpit module for storage;

[0038] When the smart cockpit module initiates a read command, the vehicle-side security guard module automatically intercepts the underlying file interface, reads the corresponding encrypted data and preset privacy configuration, and calls the quantum security module to use the pre-assigned quantum key to decrypt the data according to the preset privacy configuration, and returns the decrypted data to the smart cockpit module for reading.

[0039] Preferably, the data types of the privacy configuration include vehicle spatiotemporal information, driving monitoring data, biometric collection information, voice collection information, camera image data and lidar data.
