摘要：2020年2月，11个国家部委联合出台《智能汽车创新发展战略》，标志着车联网产业将在中国获得高速发展重大机遇，汽车电子产业发展获得智能、网联、安全新契机。

面向自动驾驶及智能网联汽车未来电子电气架构，如何研发适应于车载控制器交互场景的信息安全加固及入侵检测机制成为学术界和产业界共同关注的话题。本报告介绍了团队在车载信息安全领域的技术成果，围绕ADAS自动驾驶场景，构建适应于车载嵌入式系统的纵深防御安全体系及解决方案。同时分享了车载信息安全的技术发展趋势及信息安全推进路径，为智能网联汽车信息安全提供参考意见。

Abstract：In February 2020, 11 national ministries and commissions jointly issued the smart car innovation and development strategy, which marked that the Internet of vehicles industry will get a major opportunity for rapid development in China, and the development of the automotive electronics industry will get a new opportunity for intelligence, networking and security.

For the future electronic and electrical architecture of autonomous driving and intelligent networked vehicles, how to develop information security reinforcement and intrusion detection mechanism suitable for vehicle controller interaction scenarios has become a common concern of academia and industry. This report introduces technical achievements in the field of vehicle cyber security. Considering the ADAS autonomous driving scenario, it constructs the in-depth defense security system and solutions suitable for ECUs. Meanwhile, it presented the technology development trend and information security promotion path of vehicular cyber security, and provides reference advice for intelligent vehicle cyber security.
