Abstract: This paper designs a certificate storage system using P2P technology. Comparing to traditional certificate storage system which designed with directory service system, the certificate storage system is scalability, robust, load balance, fault tolerance. And it solves some problem of traditional directory services such as hard to configure, accessing bottleneck and so on.

Key words: P2P, Certificate Storage, Directory service system

摘要： 采用P2P技术设计了一个证书库系统，与传统的采用目录服务器设计的证书库系统相比，该系统具有良好的可扩展性、健壮性、负载平衡和容灾容错等特性，解决了传统目录服务系统不易配置，出现访问瓶颈的问题。
