P2P网络认证系统中监督机制的研究

为解决P2P网络中各种用户认证系统安全性较低的问题,提出一种监督机制保证认证协议执行过程的安全。认证协议中加入监督机制后,两个用户间进行认证的同时,另一个作为监督者的用户会被随机选出。参与认证的用户的身份会由监督者进行验证,合法用户的冒充者无法了解监督者的身份以及它如何对整个认证协议执行过程进行监督。监督机制加强了认证协议的安全性,使合法用户的身份得到了保证,进而保障了P2P网络中资源的安全。

Research on Monitoring Mechanism in P2P Network Authentication System

To solve the problem of the low security of the users' authentication systems in P2P network,a monitoring mechanism is proposed to ensure the security of the process of authentication protocol. When the monitoring mechanism is added to the authentication protocol,a third user as a supervisor of the authentication is randomly selected while two users are authenticating with each other. The supervisor will participate in the process of authentication and identify the identity of the users. The illegal user wh...
