Vehicle identity authentication system and method adapting to V2X communication

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 a
