Abstract

The invention provides an identity authentication system for vehicle-road coordination, which can reduce certificate management and storage costs, realize strong authentication of vehicle node identities for vehicle-road coordination, and quickly trace the real identity of the vehicle end when disputes occur. It includes: roadside terminals, vehicle-mounted terminals, vehicle-mounted terminals, and roadside terminals communicate with the authentication server respectively. The authentication server includes root CA, authentication CA, and anonymous CA; it also includes private key generation center PKG, security Identification; Different identity authentication mechanisms are used for different vehicle-road coordination nodes. Roadside terminals and vehicle-mounted terminals that require privacy protection use the PKI identity authentication mechanism, and vehicle-mounted terminals that do not need privacy protection use the IBC identity authentication mechanism. For vehicle-mounted terminals, add The vehicle electronic identification that uniquely identifies the trusted digital identity of the vehicle to achieve strong vehicle identity authentication. At the same time, the invention also discloses an identity authentication method for the vehicle-road coordination.

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...
