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.
本发明公开了一种车辆的防盗认证系统、车辆及车辆的防盗认证方法。基于E2E通信保护的防盗认证保护,将功能安全范畴的E2E概念引入到网络传输领域,通过E2E端到端的通信保护对随机数和计算结果进行保护,从根本上解决了由于网络传输过程中总线错误或者电压波动导致的传输信号位被篡改后通信双方却不知情的问题,避免了这种错误导致防盗认证失败,造成车辆用户无法换挡的情况,可以降低车辆用户抱怨率。本发明实施例的技术方案功能安全等级可达到ASILD,安全性高,且可执行性强,不改变控制器硬件及原有的防盗验证逻辑及流程,节约成本,只需要通过改变应用层Autosar协议栈的配置即可实现。
