Abstract

The invention provides a vehicle-road cooperation identity authentication system, which can reduce certificate management and storage overhead, realize strong authentication of vehicle-road cooperation vehicle node identities, and rapidly trace back real identities of vehicle ends when dispute events occur. The vehicle-road cooperation identity authentication system comprises a roadside terminal and a vehicle-mounted terminal, wherein the roadside terminal and the vehicle-mounted terminal are in communication connection with an authentication server, and the authentication server comprises a root CA, an authentication CA and an anonymous CA. The vehicle-road cooperation identity authentication system further comprises a private key generation center PKG, a security module and an automobileelectronic identifier, wherein different identity authentication mechanisms are used for different vehicle-road cooperation nodes; the road side terminal and the vehicle-mounted terminal needing privacy protection use a PKI identity authentication mechanism; the vehicle-mounted terminal needing no privacy protection uses an IBC identity authentication mechanism; and for the vehicle-mounted terminal, an automobile electronic identifier uniquely identifying the credible digital identity of the vehicle is added, so that strong authentication of the vehicle identity is realized. Meanwhile, the invention further discloses an identity authentication method for vehicle-road cooperation.

Description

technical field [0001] The invention relates to the technical field of intelligent traffic control, in particular to an identity authentication system and method for vehicle-road coordination. Background technique [0002] Vehicle-road coordination is the use of advanced wireless communication and new-generation Internet technologies to implement dynamic real-time information interaction between vehicles and between vehicles and roads in an all-round way, and to carry out vehicle active traffic management based on the collection and fusion of dynamic traffic information in all time and space. Safety control and collaborative road management. Various messages received in the vehicle-road coordination scenario, especially for emergencies, security incidents, etc., must be guaranteed to be sent from legal nodes. The legal nodes of the vehicle-road coordination system include on-board unit (OBU) and roadside terminal (Road Side Unit, RSU); in daily communication, RSU communicat...
