Vehicle identity authentication system and method adapting to V2X communication

Abstract

The invention relates to a vehicle identity authentication system and method adapting to V2X communication. One specific embodiment of the system comprises an IC server side and a CC server side, wherein the IC server side sends an identity authentication request of a vehicle to a first CA server side, and the first CA server side verifies the identity authentication request and returns a verification result to the IC server side; if the verification is passed, an IC server side cluster sends a request instruction for generating a communication credential to the CC server side; and the CC server side generates the communication credential based on the request instruction, and returns the generated communication credential to the vehicle through the IC server side to realize the identity authentication of the vehicle. Through adoption of the vehicle identity authentication system and method, the authentication and privacy protection can be fully balanced; the characteristics of high dynamics, high randomness and low delay in V2X communication can be met; the whole V2X communication security system can efficiently and reliably serve V2X communication; and a car factory can be guidedto form safety module of a V2X communication vehicle end easily and clearly.

Description

technical field [0001] The present invention relates to the technical field of V2X communication, in particular to a vehicle identity authentication system and method adapted to V2X communication. Background technique [0002] V2X (Vehicle to Everything) technology is a way for vehicles to communicate directly with the outside world. It does not depend on the operator's network and is different from short-distance communications such as Bluetooth and Wi-Fi. V2X is a key technology for intelligent networked vehicles. V2X includes the participation of various communication subjects such as Vehicle to Vehicle (V2V), Vehicle and Roadside Facilities (V2I). Compared with the level of information security protection and credibility of roadside facilities and network equipment, the security of V2V communication It is often the focus of most attention, especially in various scenarios such as V2V communication with high dynamics, high randomness, and vast areas, and the privacy prote...

Problems solved by technology

The problems with this solution are: 1) There is only a description of the process of applying for an AT, and there is no solution for how to ensure that the AT can apply successfully for different scenarios

The disadvantages of this technical solution are: 1) The communication certificate is not designed for the usage scenario

2) It is not clear how to deploy EA. Is it centralized or sub-regional? How to achieve load balancing? The unresolved issues are not conducive to the development of vehicle-side security modules by OEMs
