文章提出了一种在P2P网络中安全分发密钥和进行对等点身份认证的方法。这种方法采用的认证协议同时结合了公钥加密和密钥加密技术。我们还通过一种认证测试的方法证明了该方法使用的安全认证协议的正确性。-This paper presents a P2P network in the distribution of key security and authentication of the peer approach. This method of authentication protocol used in connection with a public key encryption and key encryption technology. We are also certified through a method of testing proved that the method used in the correctness of the security authentication protocol.
