PKI infrastructure architecture based on LTE-V2X

Abstract： A key factor to the success of V2X business lies in security: messages authentication and personal privacy protection. Therefore, it is mandatory to establish an identity authentication system based on the actual supervision system, and reasonably define the security boundaries and responsibilities of each participant. Based on existing V2X PKI systems: SCMS and CCMS, this paper analyzes the actual needs of the V2X certificate management system based on the LTE-V2X technical characteristics and domestic regulatory system, and gives corresponding solutions to several key processes of certificate management. And then it makes recommendations PKI infrastructure and security strategy for LTE-V2X business, puts forward specific security management solutions for domestic V2X business development in the future, which can actually be applied to the development and design of LTE-V2X service deployment and related systems.
