Embodiment 1
[0038] figure 1 Embodiment 1 of the present invention provides a schematic structural diagram of an anti-theft authentication system for a vehicle, figure 2 This is a structural diagram of an anti-theft authentication system for a vehicle provided in Embodiment 1 of the present invention. This embodiment is applicable to the situation of anti-theft authentication between the shift actuator control unit and the body control unit after the vehicle is powered on. like figure 1 and 2 As shown, the vehicle's anti-theft authentication system includes:
[0039] The actuator control unit 100 and the body control unit 200; the actuator control unit 100 is connected in communication with the body control unit 200;
[0040] The actuator control unit 100 is configured to generate a random number, DataID and Counter based on E2E when the vehicle power state of the vehicle is switched to the ignition gear of the vehicle, and calculates the number of times according to the random number,...
Embodiment 2
[0069]Embodiment 2 of the present invention provides a vehicle, wherein the vehicle includes the anti-theft authentication system for a vehicle according to any embodiment of the present invention.
[0070] The vehicle provided by the embodiment of the present invention, based on the anti-theft authentication protection of E2E communication protection, introduces the E2E concept of functional safety into the field of network transmission, and protects random numbers and calculation results through E2E end-to-end communication protection, which fundamentally solves the problem. It solves the problem that both parties of the communication are unaware of the tampering of the transmission signal bits due to bus errors or voltage fluctuations in the network transmission process, and avoids the failure of anti-theft authentication due to such errors, resulting in the vehicle user's inability to shift gears, which can reduce vehicle users. The complaint rate has effectively increased ...
Embodiment 3
[0072] Figure 5 A flowchart of a vehicle anti-theft authentication method provided in Embodiment 3 of the present invention, the vehicle anti-theft authentication method is applied to the actuator control unit, such as Figure 5 As shown, the anti-theft authentication methods for this vehicle include:
[0073] S510. When the vehicle power state of the vehicle is switched to the vehicle ignition gear, generate a random number, DataID and Counter based on E2E, and calculate and obtain a first CRC code according to the random number, the DataID and the Counter and the first calculation result message.
[0074] S520. Send the random number, the Counter and the first CRC to the body control unit, and obtain the first random number and the Counter calculated by the body control unit according to the received random number and the Counter. Two cyclic redundancy check codes to generate a second calculation result message.
[0075] Specifically, the body control unit calculates and...
