Vehicle-to-external device communication refers to the data exchange and information transmission between automobiles and external environmental equipment and systems.

[0003] While vehicle communication with external devices brings many conveniences, it also faces numerous security risks. For example, when a vehicle communicates with external devices (such as cloud services, transportation infrastructure, other vehicles, or target devices), the data may be attacked and monitored by hackers, leading to the theft or tampering of sensitive information (such as driving trajectory and driving habits), which could result in privacy leaks or flawed decision-making. For instance, if an attacker intercepts and modifies transmitted commands while the vehicle is being remotely controlled, they could change the vehicle's direction or speed, potentially causing unforeseen safety incidents.

[0004] Therefore, improving the security of communication data during communication between vehicles and external devices has become an urgent problem to be solved. Summary of the Invention

[0015] Optionally, after the first chip encrypts the second data to obtain the second encrypted data, the communication data processing method further includes: the first chip storing the second encrypted data in a memory.

[0016] Optionally, the first chip includes a first interface and a decryption unit, and the communication system includes a processor; the first chip performs hardware decryption and software decryption on the first encrypted data to obtain the first data, including: the decryption unit performs hardware decryption on the first encrypted data to obtain first decrypted data; the first chip sends the first decrypted data to the processor through the first interface; and the processor performs software decryption on the first decrypted data to obtain the first data.

[0017] Secondly, the present invention provides a vehicle communication system applied to a target vehicle. The vehicle communication system includes a first chip, a communication module, and a transmission module. The communication module is used to receive first encrypted data sent by a target device and transmit the first encrypted data to the first chip. The target device is equipped with a second chip. The first encrypted data is obtained by the second chip through software encryption and hardware encryption of the data. The second chip is adapted to the first chip.

Therefore, the first chip will not transmit the data sent by other devices to the control unit to control the operation or driving of the target vehicle, and will not cause leakage of personal information. Thus, the security of communication data during the communication process between the vehicle and the target device is improved. Attached Figure Description

[0026] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Although some embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the present invention. It should be understood that the accompanying drawings and embodiments of the present invention are for illustrative purposes only and are not intended to limit the scope of protection of the present invention.

[0027] It should be understood that the various steps described in the method embodiments of the present invention may be performed in different orders and / or in parallel. Furthermore, the method embodiments may include additional steps and / or omit the steps shown. The scope of the present invention is not limited in this respect.

[0028] The term "comprising" and its variations as used herein are open-ended, meaning "including but not limited to"; the term "based on" means "at least partially based on"; the term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one additional embodiment"; the term "some embodiments" means "at least some embodiments"; and the term "optionally" means "optional embodiments". Definitions of other terms will be given in the following description. It should be noted that the concepts of "first," "second," etc., mentioned in this invention are used only to distinguish different devices, modules, or units, and are not intended to limit the order of functions performed by these devices, modules, or units or their interdependencies.

[0029] It should be noted that the terms "a" and "a plurality of" used in this invention are illustrative rather than restrictive. Those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".

[0030] The names of the messages or information exchanged between the multiple devices in the embodiments of the present invention are for illustrative purposes only and are not intended to limit the scope of these messages or information.

[0031] In related technologies, the target device is an external device that communicates with the vehicle. Taking the target device as a remote control device as an example, the importance of improving the security of communication data during the communication process between the vehicle and the target device is explained. The real-time interaction process between the remote control device and the vehicle's communication system is as follows: When the operator issues remote control commands (such as acceleration, deceleration, steering, or parking) through the remote control device, these commands are sent to the vehicle's communication system. After receiving these commands, the vehicle's communication system forwards them to the corresponding control unit to execute the corresponding operation, thereby realizing remote control of the vehicle.

[0032] Because remote control commands directly affect a vehicle's driving status and safety, any leakage, tampering, or forgery of communication data can lead to serious consequences. For example, if attackers can intercept and modify transmitted commands, they may change the vehicle's direction or speed, potentially causing unforeseen safety incidents. Furthermore, users' personal information and vehicle location information may be leaked, leading to privacy violations and potential property losses.

[0033] To address the problems existing in the aforementioned related technologies, this embodiment provides a communication data processing method, a communication system, and a vehicle.

[0034] like Figure 1 As shown in the figure, an embodiment of the present invention provides a communication data processing method applied to the communication system of a target vehicle. The communication system includes a first chip, a communication module, and a transmission module. The communication data processing method includes:

[0035] S100, the communication module receives the first encrypted data sent by the target device and transmits the first encrypted data to the first chip, wherein the target device is equipped with a second chip, and the first encrypted data is obtained by the second chip through software encryption and hardware encryption of the data, and the second chip is compatible with the first chip.

[0036] Specifically, such as Figure 2 As shown, the communication system includes a first chip, a communication module, and a transmission module. The communication module is responsible for data communication with the target device. The communication module can use various protocols (such as Wi-Fi, Bluetooth, etc.) to achieve wireless communication or wired connection through a user interface.

[0037] When remotely controlling a target vehicle, the target device encrypts the first data used to control the vehicle's movement and sends it to the target vehicle. This encrypted data is received by the communication module in the communication system and then transmitted to the first chip. The target device contains a second chip, and the first and second chips are paired and compatible. Both chips can use the same non-volatile key. The first encrypted data, obtained by encrypting the data by one of the chips, can only be decrypted by either the same chip or the other compatible chip.

[0038] S200, the first chip performs hardware decryption and software decryption on the first encrypted data to obtain the first data.

[0039] Specifically, after the target device generates the first data, the second chip in the target device performs software encryption and hardware encryption to form the first encrypted data. The target device sends the first encrypted data to the communication system in the target vehicle, where the communication module receives and transmits it to the first chip. Since the first encrypted data is obtained by encryption through the second chip adapted to the first chip, the first chip can decrypt it to obtain the first data.

[0040] The primary data can include driving instructions, driving speed, driving direction, etc., as well as sensitive data such as user personal information and vehicle driving trajectory.

[0041] S300, the transmission module sends the first data to the control unit in the target vehicle.

[0042] Specifically, after the first chip decrypts the first encrypted data to obtain the first data, the transmission module is responsible for transmitting the first data to the control unit of the target vehicle. The control unit is used to control the target vehicle according to the first data. When the target device is used as a remote control device to remotely control the target vehicle, the first data is a remote control command. The control unit directs the vehicle to drive according to the remote control command, thereby realizing remote control.

[0043] In this embodiment, the data sent from the target device to the target vehicle is encrypted by a second chip. The second chip is compatible with the first chip. The first encrypted data obtained by the second chip in the target device is decrypted by the first chip using both hardware and software. Only the first data decrypted by the first chip is sent by the transmission module to the control unit to control the target vehicle. The first chip can only decrypt the data encrypted by the second chip. During transmission, even if the first encrypted data is intercepted, it cannot be decrypted without the first chip, thus preventing theft or tampering. Even if other devices send control data to the target vehicle, since this data is not the data encrypted by the second chip sent by the target device, the first chip in the communication system cannot decrypt it. Therefore, the first chip will not transmit the data sent by other devices to the control unit to control the operation or driving of the target vehicle, and personal information will not be leaked. Thus, the security of communication data during the communication between the vehicle and the target device is improved.

[0044] Optionally, the communication data processing method further includes: the transmission module receiving second data from the target vehicle and transmitting the second data to the first chip; the first chip performing software encryption and hardware encryption on the second data to obtain second encrypted data.

[0045] Specifically, in addition to processing the data sent by the target device, the communication data processing method also encrypts the second data generated by the target vehicle during its operation. The second data includes sensitive information such as the vehicle's real-time location, driving trajectory, and personal identity information. This second data needs to be protected, so the first chip is used to encrypt the second data.

[0046] Optionally, the first chip includes a first interface and an encryption unit, and the communication system includes a processor. The first chip performs software encryption and hardware encryption on the second data to obtain second encrypted data, including: after receiving the second data, the first chip transmits the second data to the processor through the first interface; the processor performs software encryption on the second data to obtain third encrypted data, and transmits the third encrypted data to the encryption unit through the first interface; the encryption unit performs hardware encryption on the third encrypted data to obtain the second encrypted data.

[0047] Specifically, the communication system also includes a processor. The first chip includes a first interface and an encryption unit. The first chip and the processor transmit data to each other through the first interface. After the first chip receives the second data, it first transmits the second data to the processor through the first interface. The algorithm stored in the processor performs software encryption on the second data. The third encrypted data obtained through software encryption is then transmitted to the first chip through the first interface. The encryption unit in the first chip performs hardware encryption on the third encrypted data to obtain the second encrypted data.

[0048] Combining software and hardware encryption for the second data creates a dual-protection mechanism. Software encryption performs initial encryption at the processor level, while hardware encryption provides stronger security at the chip level. This multi-layered protection significantly improves data confidentiality and reduces the risk of being cracked.

[0049] Optionally, the communication system further includes a first storage module, which stores the encryption algorithm of the encryption unit in a non-volatile manner; the encryption unit performs hardware encryption on the third encrypted data, including: the encryption unit loads the encryption algorithm from the first storage module; and performs hardware encryption on the third encrypted data according to the encryption algorithm.

[0050] Specifically, such as Figure 3 As shown, the communication system includes a first storage module. This first storage module uses non-volatile storage to store the encryption algorithm, ensuring that the stored encryption algorithm is retained even when the device is powered off or restarted, thus guaranteeing the system's reliability and continuity. The encryption unit loads the encryption algorithm from the first storage module for hardware encryption. Using a separate storage module to store the encryption algorithm allows for easy updating or replacement of the encryption algorithm when needed.

[0051] It should be noted that non-volatile storage methods can be flash memory or fireproof storage.

[0052] Optionally, after the first chip performs software encryption and hardware encryption on the second data to obtain the second encrypted data, the communication data processing method further includes: the first chip transmitting the second encrypted data to the communication module; and the communication module sending the second encrypted data to the target device.

[0053] Specifically, the second encrypted data obtained after the second data passes through the first chip is transmitted to the communication module, which then sends it to the target device, ensuring the security of the second data when it is fed back to the target device. The target device decrypts the first encrypted data to obtain the second data, and the target device can make intelligent decisions based on the second data.

[0054] Optionally, after the first chip performs software encryption and hardware encryption on the second data to obtain the second encrypted data, the communication data processing method further includes: the first chip storing the second encrypted data in a memory.

[0055] Specifically, the encrypted second data is stored in the internal memory of the first chip. The memory can be a volatile memory such as static random access memory (SRAM), or it can be flash memory, EEPROM, or other types of non-volatile memory capable of retaining data even when the device is powered off.

[0056] Encrypted storage ensures that only the target device can access the second data. Even if the storage is physically accessed, the data cannot be easily deciphered, further enhancing the system's security.

[0057] Optionally, the first chip includes a first interface and a decryption unit, and the communication system includes a processor; the first chip performs hardware decryption and software decryption on the first encrypted data to obtain the first data, including: the decryption unit performs hardware decryption on the first encrypted data to obtain first decrypted data; the first chip sends the first decrypted data to the processor through the first interface; and the processor performs software decryption on the first decrypted data to obtain the first data.

[0058] Specifically, the communication system also includes a processor. The first chip includes a first interface and an encryption unit. The first chip and the processor transmit data to each other through the first interface. After the first chip receives the first encrypted data sent by the target device, it first performs hardware encryption on the first encrypted data through the decryption unit to obtain the third encrypted data. The third encrypted data obtained by hardware decryption is then transmitted to the processor through the first interface. The processor performs software encryption on the third encrypted data to obtain the first data.

[0059] Optionally, such as Figure 3 As shown, the communication data includes first encrypted data and second encrypted data. The communication data is transmitted between the target device and the target vehicle through a user interface, antenna, or tuner. Specifically, the target device transmits the first encrypted data to the first chip through the user interface, antenna, or tuner. The second encrypted data of the first chip in the target vehicle is transmitted to the target device through the user interface, antenna, or tuner. After decryption, the first data obtained by the first chip is sent to the controller (entertainment network device and main device) to remotely control the target vehicle. During vehicle operation, the controller sends the second data to the first chip, which is then encrypted to obtain the second encrypted data. In the figure, the CPU is the processor, which is used to perform software encryption or software decryption of the data. FLASH (flash memory) is used for the encryption algorithm of the first chip, and static random access memory (SRAM) is used to store the second encrypted data.

[0060] like Figure 4 As shown, the first chip is a field-programmable gate array (FPGA) encryption chip. The FLASH (first storage module) stores the encryption algorithm. The encryption algorithm is used to program the first chip. The CPU interface (first interface) connects the first chip and the CPU processor. The CPU is used to perform software encryption and software decryption of data. The SDRAM (Dynamic Random Access Memory) is used to store temporary second encrypted data.

[0061] The user interface and antenna / tuner serve as communication modules, enabling interaction between the first chip and the target device. Decrypted data is transmitted to other components of the vehicle (SDRAM, entertainment network equipment, main equipment, etc.) via internal local interconnect bus (LIN interface), control area bus (CAN controller), external controller interface (PCI bridge), memory controller, etc. The FLASH (flash memory) algorithm is transmitted to the first chip via PCMCIA (Personal Computer Memory Card International Association) interface. Data received by the antenna / tuner is transmitted to the first chip after filtering and formatting. The first chip also performs specific logic functions, such as simple control and signal processing.
