P2P网络离散、动态和自治的特点使得传统的认证方法不能很好的解决其认证问题.采用证书和信任值相结合的方式,提出了一个新的认证协议APExSPKI用于解决P2P网络中节点之间的互认证问题.信任值绑定在证书中使得节点在身份认证的同时还可以进行授权和访问控制操作.此外APExSPKI不需要可信服务器的参与,它允许网络中的任何节点参与到认证的过程中来,参与信任值投票并可充当代理节点来为其他节点颁发证书,这充分体现了节点对等、自治的特点.
The discrete, dynamic and autonomic characteristics of P2P networks make the traditional authentication methods not well solve their authentication problems.A new authentication protocol APExSPKI is proposed to solve the problem of nodes in P2P networks by adopting a combination of certificates and trust values. Of the mutual authentication problem.The binding of the trust value in the certificate allows the node to carry out the authorization and access control operations simultaneously with the authentication.Another APExSPKI does not require the participation of the trusted server which allows any node in the network to participate in the authentication process In the vote to participate in the trust value and can act as a proxy node to issue certificates for other nodes, which fully reflects the peer peer autonomous features.
