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.
