摘　　要：PKI的目的是证明对于确定的用户而言,公开密钥是否可信。与集中式目录相比,对等网络如何处理分布式的PKI中关于数字证书的询问,证明公开密钥的真实性。通过引入Chord协议,一个能够解决这个问题的分布式查询协议,提高了验证的效率。并进行了一种以可扩展Chord为查找协议的公钥验证的设计和实现。The goal of a PKI is to prove whether a public key is authentic for a certain user. In comparison to centralized directories, how P2P networks to deal with a large number of queries for certificates that attest the authenticity of public keys. By introducing Chord protocol, a distributed lookup protocol that addresses this problem, brings a high efficiency on public key＇s authentication. Finally, a design and realization is done to public key＇s authentication based on a Chord protocol.
