摘　　要：介绍了V2X通信对数字签名技术的需求和应用,以及目前基于PKI的V2X安全认证防护体系架构及其优缺点,随后进一步提出了基于联盟链构建V2XCA可信列表的管理方法,以解决多CA互信问题,并通过实现V2X CA信任列表分布式、去中心化的存储和快速同步,提升V2X通信安全体系的效率,同时降低管理维护成本。This paper introduces the requirement and application of digital signature technology in V2X communication,as well as the current PKI-based V2X security authentication and protection architecture,and its advantages and disadvantages.Then a novel management method is proposed to build a V2X CA trusted list based on consortium block-chain,and thus the issue of mutual trust among multiple CAs is solved.Furthermore,through realizing a distributed V2X CA trusted list with decentralized storage and fast synchronization,the efficiency of the V2X communication security system is improved,and the management and operation cost is also reduced.
