为解决一般的身份鉴别机制不适用于具有匿名通信要求的P2P网络系统模型的难题。通过对Diffle-Hellman密钥协商协议进行改进,并结合采用RSA数字签名协议,以及零知识证明GQ协议,提出了一种新的基于服务令牌对P2P匿名通信系统中的通信双方进行身份鉴别的机制。该机制在保证P2P匿名通信系统各种普遍特征的前提下,通过在P2P匿名通信系统中引入可信第三方节点,针对P2P匿名通信系统中各通信节点进行匿名控制和行为管理,同时既可抵御各种常见网络攻击的威胁,又有效实现了P2P匿名通信系统的身份鉴别,从而有效提高了P2P匿名通信系统的安全性,加强了此种系统的管理能力。
To solve the general identity authentication mechanism is not suitable for P2P network system with anonymous communication requirements model problems. By improving the Diffie-Hellman key agreement protocol and combining with the RSA digital signature protocol and zero-knowledge proof GQ protocol, a new service token based authentication for identity authentication of both communication parties in P2P anonymous communication system mechanism. Under the premise of ensuring various common features of P2P anonymous communication system, this mechanism introduces anonymous third-party nodes into P2P anonymous communication system and controls anonymity and behavior of every communication node in P2P anonymous communication system, Threat of all kinds of common network attacks, and effectively realize the identity authentication of P2P anonymous communication system, so as to effectively improve the security of P2P anonymous communication system and strengthen the management ability of such system.
