Description

Technical Field

[0001] The present invention belongs to the field of intelligent networked vehicles, and specifically relates to an intelligent networked vehicle communication method, system and related devices. Background Art

[0002] The electrification, intelligence, networking and sharing of automobiles will become new trends in the future development of the industry. In the era of smart mobile terminals, the form of automobile products has been comprehensively innovated, the boundaries have been continuously extended, and automobiles have become nodes of the Internet of Everything. Security risks involve vehicle parts and buses, wireless communications, software, and also roadside equipment, cloud management platforms, and IoT terminals. The security risks of smart connected vehicles mainly include external network security risks, internal network security risks, and other network security risks.

[0003] The information security of intelligent connected vehicles is one of the areas in the scope of national security. At present, the safety of the whole vehicle is not only functional safety, but also information security. Due to the upgrade of automation capabilities, the information security of intelligent connected vehicles needs to include at least three aspects: "cloud, pipe, and end". The information security protection of intelligent connected vehicles has become the focus of attention of the automotive industry and even society. Information security protection needs to be considered from multiple angles: end, pipe, and cloud, analyze the threats faced by the car, strengthen data access control throughout the life cycle, improve the identity authentication system during the use of the vehicle, and build an active information security protection system that runs through the three levels of "end, pipe, and cloud".

[0004] At present, the security protection of intelligent connected vehicles is mainly carried out from four levels: hardware security, operating system security, application security, and internal and external communication security. The main security protection measures are: using hardware security modules to ensure the security of vehicle-side hardware; using identity authority management and access control mechanisms to ensure the security of the operating system level; the application layer has the ability to update security, resist attacks, and encrypt data storage; and ensuring data confidentiality, integrity, and communication quality at the internal and external communication level.

[0005] At present, the data transmission encryption technology of intelligent connected vehicles is mainly used for line encryption and end-to-end encryption. Line encryption focuses on the line without considering the source and destination of the information, and uses different keys to protect confidential information through each line. End-to-end encryption means that the information is automatically encrypted by the sender and encapsulated in data packets by TCP / IP, and then passes through the communication network as unreadable and unrecognizable data. When this information is received, it will be automatically reassembled and decrypted to become readable data. With the continuous escalation of end-side security threats and the development of supercomputing technology and quantum technology. The security threats to intelligent connected vehicles are becoming more and more serious, and end-to-end and line encryption need to be improved.

[0006] In summary, the typical security risks of smart connected cars are as follows: 1. Cloud platform security risks: The cloud backend is exploited / nodes are counterfeited / network data is hijacked, etc., resulting in sensitive information leakage or illegal vehicle control; 2. Data security sharing: Currently, intelligent connected vehicles continuously collect road information, vehicle operating conditions, and user personal information, which may be illegally updated or sensitive information may be leaked; 3. Communication transmission security risks: Malicious node attacks may cause leakage of sensitive information; 4. Security risks of the terminal itself: Smart connected vehicles are equipped with a large number of sensors. Taking the positioning terminal as an example, if the positioning terminal is sent a false location signal, it may lead to automatic driving by mistake, with disastrous consequences.

[0007] Therefore, the full-link data security of intelligent connected vehicles is related to many aspects such as personal declaration security, road information data security, and citizen privacy security. Summary of the invention

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and are not to be construed as limitations of the present invention.

[0025] Terminology explanation: Intelligent connected car: mainly refers to intelligent car terminals. It covers different scenarios such as intelligent cockpit, intelligent driving, intelligent power and intelligent gateway. The "terminal" promotes the intelligence of car terminals through AI chips and computing platforms based on AI chips.

[0026] Management side: mainly realizes the interconnection and mutual coordination between vehicles, vehicles and people, vehicles and roadside units, and vehicles and the cloud through intelligent networking. "Management" is the key part to ensure information exchange and coordination between vehicles and between vehicles and the external environment.

[0027] Cloud Center: It includes the autonomous driving training system and the Internet of Vehicles cloud platform, providing cloud computing power and service content for the Internet of Vehicles. The "cloud" is an important foundation for realizing functions such as autonomous driving, remote monitoring, data analysis and processing.

[0028] OBD, On-Board Diagnostics, that is, vehicle automatic diagnostic system; KEK, Key Encryption Key, that is, key encryption key; VPN, Virtual Private Network, that is, virtual private network; QKD, Quantum Key Distribution, means quantum key distribution.

[0029] This invention mainly focuses on the end-to-end communication of intelligent networked vehicles and the line encryption between "end, pipe and cloud", integrating quantum technology to comprehensively improve security capabilities. It adopts the integration of quantum true random number generation technology and existing end-to-end data transmission to improve the data transmission security between intelligent networked vehicles and the end-to-end data transmission security between management terminals and cloud centers by using QKD technology.

[0030] This invention integrates quantum security technology into the key link of intelligent networked vehicle communication. It uses the natural unconditional security characteristics of quantum security technology to comprehensively improve the data transmission security of intelligent networked vehicles. The specific solution is described as follows: like Figure 1 As shown, the present invention provides a communication method for intelligent connected vehicles based on quantum fusion encryption, which is applied to intelligent connected vehicles and includes the following steps: S100, generating a quantum true random number and storing it in the form of ciphertext to form a quantum true random key; receiving a key request from a quantum encryption service platform, and synchronizing the quantum true random key to the quantum encryption service platform; S200, generating local plaintext data based on the quantum true random number; encrypting the local plaintext data using an algorithm based on a quantum key to obtain a ciphertext, and transmitting the ciphertext to a quantum encryption service management cloud platform; S300, receiving data or operation commands issued by the quantum encryption service management cloud platform; the issued data or operation commands are: the quantum encryption service management cloud platform decrypts the ciphertext; and encrypts the decrypted data with a quantum key, and transmits it to the intelligent connected vehicle management cloud platform; the intelligent connected vehicle management cloud platform decrypts the ciphertext with a QKD-based key; the decrypted data is sent to various servers for further processing, and data or operation commands are issued.

[0031] The present invention mainly provides a communication method for intelligent connected vehicles based on quantum fusion encryption, the principle of which is: 1) Generation and storage of quantum true random keys: Using the unpredictability and non-cloning properties of quantum mechanics, truly random numbers are generated, which are used as quantum keys. These keys are stored in the form of ciphertext, ensuring the security of the keys themselves.

[0032] 2) Key synchronization: When the quantum encryption service platform issues a key request, the intelligent connected vehicle synchronizes the generated quantum true random key to the platform. This synchronization process can be carried out in the form of a key encryption key, further enhancing the security of the transmission process.

[0033] 3) Data encryption and transmission: Intelligent connected vehicles use quantum key-based algorithms to encrypt local plaintext data and generate ciphertexts, which are then transmitted to the quantum encryption service management cloud platform.

[0034] On the cloud platform, the ciphertext is decrypted and further encrypted using the quantum key as needed, and then transmitted to the intelligent connected vehicle management cloud platform.

[0035] 4) Data decryption and processing: After receiving the encrypted data, the intelligent connected vehicle management cloud platform uses the QKD-based key to decrypt it. The decrypted data is sent to various servers for further processing, and data or operation commands are issued as needed.

[0036] 5) QKD: QKD uses the principles of quantum mechanics to securely distribute keys between communicating parties. By sending single photons and measuring their polarization states, QKD can ensure that the keys cannot be eavesdropped or tampered with during transmission.

[0037] Therefore, the QKD of the present invention is based on the basic principles of quantum mechanics, which makes the key unforgeable and unstealable during the transmission process. This feature provides unprecedented security for intelligent networked car communications. The generation of quantum true random numbers ensures the physical randomness of the key, which cannot be predicted or copied by calculation, thereby further enhancing the security of the encryption process.

[0038] Furthermore, since quantum communication can use the characteristics of quantum entanglement to achieve ultra-long-distance communication transmission, this is particularly important for intelligent connected vehicle systems that require wide coverage. Quantum communication can achieve high-speed, large-capacity information transmission, meeting the needs of massive data transmission in intelligent connected vehicle systems.

[0039] Furthermore, quantum communication technology can play a role in multiple levels such as data encryption, key management, and storage encryption, providing a multi-level in-depth defense strategy for intelligent connected vehicles and effectively responding to various information security threats.

[0040] The intelligent connected vehicle communication method based on quantum fusion encryption has the advantages of high security, physical randomness, ultra-long-distance communication capability, and large data transmission capability.

[0041] As an optional solution, the quantum key is synchronized to the quantum encryption service platform and the key is transmitted in the form of a key encryption key. The key encryption key method enhances security by using an additional layer of encryption to protect the quantum key itself. Even if it is intercepted during transmission, it is difficult to crack the inner quantum key. The key encryption key method ensures that even if the outer encryption is cracked, the inner quantum key remains secure, thereby preventing the leakage of the key. This double-layer encryption method increases the system's resistance to external attacks and improves the robustness of the entire communication system.

[0042] As a further optional solution, before the intelligent connected vehicle management cloud platform uses the QKD-based key to decrypt the ciphertext, it also includes: detecting the quantum signal and generating a quantum key that is symmetric with the ciphertext in the quantum encryption service management cloud platform.

[0043] By detecting quantum signals and generating symmetric quantum keys, it is ensured that the keys used in the encryption and decryption processes are consistent, thereby ensuring the correct decryption of the data. Decryption using the symmetric keys generated by QKD utilizes the principles of quantum mechanics to ensure the security and unpredictability of the keys. The use of symmetric keys reduces the computational complexity of the encryption and decryption processes, thereby improving communication efficiency.

[0044] By enhancing security, preventing key leakage, ensuring key symmetry, improving the security of the decryption process and communication efficiency, it provides significant advantages for intelligent connected vehicle communication methods based on quantum fusion encryption. These advantages work together in the intelligent connected vehicle communication system to improve overall security and performance.

[0045] The second object of the present invention is to provide an intelligent connected vehicle communication system based on quantum fusion encryption, comprising: an intelligent connected vehicle, a quantum encryption service management cloud platform and an intelligent connected vehicle management cloud platform; The intelligent connected vehicle generates a quantum true random number and stores it in the form of ciphertext to form a quantum true random key; receives a key request from a quantum encryption service platform, and synchronizes the quantum true random key to the quantum encryption service platform; The intelligent networked vehicle generates local plaintext data based on the quantum true random number; encrypts the local plaintext data using an algorithm based on a quantum key to obtain ciphertext, and transmits the ciphertext to a quantum encryption service management cloud platform; The quantum encryption service management cloud platform decrypts the ciphertext; encrypts the decrypted data using a quantum key, and transmits it to the intelligent connected vehicle management cloud platform; The intelligent connected vehicle management cloud platform uses a QKD-based key to decrypt the ciphertext; the decrypted data is sent to various servers for further processing, and data or operation commands are sent to the intelligent connected vehicle.

[0046] The above-mentioned intelligent connected vehicle communication system based on quantum fusion encryption is based on quantum fusion encryption technology and aims to improve the security and data protection capabilities during the communication process. Its principles are as follows: 1. Quantum true random number generation and key management Generation of quantum true random numbers: Smart connected cars use quantum physics phenomena to generate true random numbers, which are theoretically unpredictable and non-replicable, and therefore more secure than random numbers generated by traditional random number generators.

[0047] Key storage and synchronization: The generated quantum true random number is used as a key and stored in the intelligent connected car in ciphertext form, which increases the security of the key. When the quantum encryption service platform initiates a key request, the intelligent connected car synchronizes the key to the service platform to ensure that both parties share a secure key.

[0048] 2. Data encryption and transmission Local data encryption: Intelligent connected cars use quantum key encryption algorithms (such as quantum one-time pads) based on quantum true random keys to encrypt local plaintext data and generate ciphertext. This step ensures the confidentiality of data during transmission.

[0049] Ciphertext transmission: The encrypted ciphertext is transmitted to the quantum encryption service management cloud platform through the communication network. Due to the use of quantum key encryption, even if the ciphertext is intercepted, it cannot be decrypted by unauthorized third parties.

[0050] 3. Key exchange and decryption between cloud platforms Decryption and re-encryption of the quantum encryption service management cloud platform: After receiving the ciphertext, the quantum encryption service management cloud platform uses the quantum key shared with the intelligent connected car to decrypt and obtain the plaintext data. Then, the cloud platform uses the quantum key (which may be the key shared with the intelligent connected car management cloud platform) to encrypt the plaintext data again and prepare to transmit it to the next cloud platform.

[0051] Decryption of the intelligent connected vehicle management cloud platform: After receiving the ciphertext, the intelligent connected vehicle management cloud platform uses the key obtained based on quantum key distribution (QKD) technology to decrypt it, ensuring that only legitimate recipients can obtain the plaintext data.

[0052] 4. Data processing and distribution Data processing: The decrypted data is sent to various servers for further processing, such as data analysis, storage, etc.

[0053] Data or operation command issuance: The processed data or operation command is issued to the intelligent connected vehicle through a secure channel to achieve remote control and data update.

[0054] The unpredictability and non-replicability of quantum keys ensure extremely high security during data transmission, which is difficult to crack even in the face of quantum computers. During the data transmission process from the intelligent connected car to the final server, the data is encrypted and decrypted multiple times, and each layer uses an independent key, which increases the overall security of the system. The key exchange and data transmission between cloud platforms are also based on quantum key technology, ensuring the security of data transmission between cloud platforms.

[0055] Therefore, the intelligent connected vehicle communication system of the present invention realizes full-process secure communication from the vehicle to the cloud platform and then to the server through quantum fusion encryption technology, effectively improving the security and reliability of the intelligent connected vehicle communication system.

[0056] The intelligent connected vehicle communication system based on quantum fusion encryption of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0057] The present invention is based on the vehicle-cloud-cloud communication scenario. That is, firstly, a communication connection is established between the vehicle and the cloud to realize data exchange, control command transmission and information sharing between the vehicle and the cloud platform; secondly, encrypted transmission, backup or interaction of vehicle uploaded data is carried out between clouds.

[0058] The main structure of the present invention is as follows Figure 2 As shown, it mainly includes intelligent connected vehicle management cloud platform, quantum encryption service management cloud platform, and intelligent connected vehicles.

[0059] In the intelligent networked vehicle communication system based on quantum fusion encryption of the present invention: 1. The modules included in the intelligent connected car are: 1) Vehicle sensors: mainly include vehicle cameras, lidar, microphones, OBD modules and other sensor components for obtaining vehicle information; 2) Vehicle computer system: mainly includes vehicle automatic control system, on-board computer and other software and hardware systems used for vehicle control and comprehensive information processing interaction; 3) Vehicle quantum true random number generator module: generates unbreakable quantum true random numbers to provide keys for intelligent connected vehicle data; 4) Vehicle key storage module: This module encrypts and stores the binary plaintext key generated by the quantum true random number module; 5) Vehicle key management module: used to coordinate the rate matching problem between key generation and encryption and decryption modules; 6) Vehicle key synchronization module: used to receive requests from the quantum management cloud platform and synchronize the quantum true random keys of the intelligent connected vehicles. Generally, the key transmission is carried out in the form of KEK; 7) Vehicle encryption and decryption module: used to encrypt outgoing data of intelligent connected vehicles and decrypt received data; 8) Vehicle communication module: used for information transmission between intelligent connected vehicles and cloud platforms, usually operator networks.

[0060] In order to increase the security of the intelligent network, a quantum true random number generator module will be installed on the intelligent network car, and the synchronization key will be dynamically controlled through the cloud platform. And a distributed quantum true random number key is used. Compared with the risk of large-scale information leakage after the centralized key is broken, the security level can be improved; In the entire system architecture, in the public network channel, the plaintext does not land. Between the intelligent connected car and the quantum key cloud platform, the key generated by the quantum true random number generator is used to encrypt the data of the vehicle sensor and the vehicle system. The present invention recommends the use of KEK to achieve wireless synchronization of quantum true random number keys; under the condition of transmission between clouds, the QKD technology is used to encrypt the plaintext.

[0061] 2. The quantum encryption service management cloud platform includes the following modules: The first part is the true random encryption and decryption module: 1) Encryption service key management module: used to coordinate the rate matching between key generation and encryption and decryption modules; 2) Encryption service key synchronization module: a module used to synchronize keys with intelligent connected vehicles; 3) Encryption service key storage module: used to encrypt and store quantum true random keys for transmission with intelligent connected vehicles; 4) Encrypted service communication module: used for information transmission between intelligent connected vehicles and cloud platforms, usually operator networks; The second part is the quantum key encryption and decryption module: 1) Encryption service QKD device - transmitter: used to generate and modulate quantum state signals, and negotiate with the receiver to generate quantum keys; 2) Encryption service quantum key management equipment: used to manage quantum keys; 3) Encryption service quantum encryption management server: used to manage the quantum network; 4) Encryption service optical quantum router: used for quantum and classical channel routing switching; 5) Encryption service quantum VPN: used to implement data transmission channels based on quantum key encryption.

[0062] 3. The intelligent connected vehicle management cloud platform mainly includes the following modules: 1) Networked QKD device - receiving end: used to detect quantum signals and generate symmetric quantum keys through negotiation with the sending end; 2) Networked quantum key management equipment: used for centralized management of quantum keys; 3) Networked optical quantum router: used for routing switching between quantum channels and classical channels; 4) Netlink Quantum VPN: used to realize data transmission channels based on quantum key encryption; 5) Network management server: used for remote management of intelligent networked vehicles; 6) Networked data storage server: used to store data of intelligent networked vehicles; 7) Connected computing server: used to implement cloud computing functions for intelligent connected vehicles.

[0063] The data transmission in the present invention is divided into two parts. The first part is the uplink data from the intelligent connected vehicle to the intelligent connected vehicle management cloud platform, and the second part is the downlink data sent by the cloud platform to the connected vehicle.

[0064] The present invention adopts a quantum key-based encryption method during data transmission to achieve data transmission security. The specific encryption steps are as follows: 1) The quantum true random number module generates quantum true random numbers and stores them in the key storage module in the form of ciphertext; 2) The true random encryption and decryption module of the quantum encryption service platform sends a key request to the intelligent connected vehicle, and the vehicle key synchronization module synchronizes the quantum key to the quantum encryption service platform; 3) Intelligent connected car sensors and vehicle systems generate local plaintext data; 4) The vehicle encryption and decryption module encrypts the local plaintext data using a quantum key-based algorithm and transmits it to the quantum encryption service management cloud platform through a wireless channel; 5) The true random encryption and decryption module of the quantum encryption service management cloud platform decrypts the ciphertext sent by the intelligent connected car; 6) The QKD encryption module encrypts the decrypted data using a quantum key and transmits it to the intelligent connected vehicle management cloud platform; 7) The intelligent connected vehicle management cloud platform uses QKD-based keys to decrypt ciphertext; 8) The decrypted data is sent to various servers for further processing; 9) The data or operation commands issued by the intelligent connected vehicle management cloud platform are returned to the intelligent connected vehicle through the original route.

[0065] The present invention adopts quantum true random number technology to improve the data security of current intelligent networked vehicles. In view of the existing mathematical encryption method, a physical key generation method is adopted to achieve an upgrade of the security properties of the key.

[0066] On the end-to-cloud side, quantum fusion encryption technology based on the fusion of QKD technology and classical encryption is used to add another security lock to the current line distribution; through the method of the present invention, the security solution of the entire link of the output transmission of connected vehicles is fundamentally innovated.

[0067] This solution uses two quantum encryption schemes, one is the quantum true random number key distribution technology for the mobile scenario of intelligent connected vehicles, and the other is the QKD technology between the management end and the cloud service center. From the scenario point of view, it realizes the full-link security protection of data in limited channels and wireless channels.
