This section will mainly introduce the cutting-edge technology of intelligent networked vehicles in the network security level，including the application background and control plane of the automotive zero trust model，the application，practice and ecological construction of endogenous security technologies，and the key technologies for the trusted operation of the Internet of Vehicles. The zero-trust model mainly solves the inherent problem of the concept of “building trust based on network boundaries”，and can effectively protect network communication and business access without relying on the physical security mechanism of the network transport layer. The endogenous safety theory of intelligent and connected vehicles is an original theoretical technology proposed by the Chinese scientific research team. Endogenous security- generalized robust control is the first technology that publicly claims to provide an integrated guarantee solution for network security and functional safety of intelligent networked vehicles. Its technical application T-Box system has been carried out in real-vehicle verification and testing，black and white box testing，etc.，and is now striving to promote industrialization.
