V2X PKI信任模型研究分析

Analysis and Research on Network Trust Models Based on V2X PKI

信任模型是建立公钥基础设施信任体系的基础,决定着在构建整个PKI信任体系及进行跨域认证的技术框架。在车联网V2X PKI体系中,建立不同CA之间的信任模型,解决CA之间的互信互认是车联网V2X PKI大规模商用必须解决的问题。文章通过深入分析常见的几种CA信任模型的基础上,结合欧美V2X PKI信任模型的比较,并结合我国PKI标准及行业发展现状,对我国V2X PKI的网络信任模型进行了分析并提出建议。

The trust model is the basis for establishing a public key infrastructure trust system,which determines the technical framework for building the entire PKI trust system and cross-domain authentication.In the V2X PKI system,establishing a trust model between different CAs and solving the mutual trust and mutual recognition between CAs is a problem that must be solved for large-scale commercial use of V2X PKI.Based on the in-depth analysis of several common CA trust models,combined with the comparison of European and American V2X PKI trust models,and combined with my country's PKI standards and industry development status,this paper analyzes the network trust model of my country's V2X PKI and makes recommendations.
