摘要
自动驾驶技术的量产化需要面对的一大挑战为互联通讯中的网络信息安全。本文详细介绍了车身网络的不同信息安全需求和对应解决方案。针对具备采用无线更新软件SOTA功能的车载网络通讯,需要一种基于具有硬件信息安全模块的微处理器解决方案。它在现有的车身网络中以很小的数据开销保护信号的完整性、安全认证和时效性。同时描述了使用功能安全和信息安全相结合的方法进行系统开发和方案制定。进而介绍了功能安全和信息安全相关保护机制的验证方法。
One of the biggest Challenge of Full Automated Driving Vehicle mass production is the Cyber Security of Connectivity. This paper describes the different Cyber Security requirement and related solution of Onboard Network. For Onboard Network ready for SOTA, Embedded hardware based Cyber Security module is necessary. It guarantees the integrity, authenticity, and freshness based on acceptable data load. This paper also describes design the system and solution with both functional safety and cyber security method. Furthermore, the method of confirmation of safety and security mechanism is also introduced.
