C-V2X equipment identification management and authentication mechanism

Cellular vehicle-to-everything (C-V2X) is the most promising V2X communication technology which can greatly improve traffic efficiency and road safety. However, when vehicles are interconnected with the surrounding radio environment, the CV2X system will face various network security risks and threats, significantly impacting on traffic and life safety. This paper proposes a novel unified identification management framework and security authentication mechanism for the C-V2X equipment based on the security problems analyses of the C-V2X system and the existing security protection schemes. This paper also presents the security analysis and evaluation for the united identification management and authentication mechanism. A experiment system is implemented to verify feasibility and effectiveness for the proposed mechanism.
