摘　　要：公钥基础设施(PKI)作为解决网络通信中的信息安全问题的重要基础设施,其自身的生存性是系统安全性之上必须考虑的问题。传统的基于目录服务的PKI证书系统很少考虑生存性问题,存在着单点失效等生存性缺陷。针对这些问题,提出了一种基于P2P存储技术的PKI证书系统生存性增强策略,并在具体的P2P存储技术BitVault的基础上给出了高生存性PKI系统的实现方法。Public key infrastructure （PKI） as an important infrastructure to address information security issues in communications network, whose own survivability should be considered beyond security for the system. The traditional PKI certificate system that based on directory service with little regard for survival issues, there is a single point of failure such as the existence of defects. In this paper, to solve such problems, gives a survivability enhancement strategy based P2P-storage-technology for PKI certificate system and gives an implementation method using a P2P- storage-technology named BitVault.
