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...

Abstract

The invention discloses an anti-theft authentication system of a vehicle, the vehicle and an anti-theft authentication method of the vehicle. According to the anti-theft authentication protection based on E2E communication protection, an E2E concept in a functional security category is introduced into the field of network transmission, and random numbers and calculation results are protected through E2E end-to-end communication protection. The problem that two communication parties do not know that transmission signal bits are tampered due to bus errors or voltage fluctuation in the network transmission process is fundamentally solved, the situation that vehicle users cannot shift gears due to anti-theft authentication failure caused by the errors is avoided, and the complaint rate of the vehicle users can be reduced. According to the technical scheme provided by the embodiment of the invention, the function security level can reach ASILD, the security is high, the performability is strong, the controller hardware and the original anti-theft verification logic and process are not changed, the cost is saved, and the method can be realized only by changing the configuration of the Autosar protocol stack of the application layer.

Description

technical field [0001] The invention relates to the technical field of vehicle network communication, in particular to an anti-theft authentication system for a vehicle, a vehicle and an anti-theft authentication method for the vehicle. Background technique [0002] The vehicle shift anti-theft function means that in a vehicle equipped with a shift actuator control unit, the vehicle shift operation is only allowed after legal authentication between the shift actuator control unit and the body control unit. , an anti-theft prompt will be displayed on the instrument panel. SUMMARY OF THE INVENTION [0003] The invention provides an anti-theft authentication system for a vehicle, a vehicle and an anti-theft authentication method for the vehicle, so as to solve the failure of the anti-theft authentication caused by the bus error or voltage fluctuation during the transmission of the vehicle network, thereby causing the vehicle user to be unable to perform a gear shift operation...
