基于P2P模式的身份验证系统

P2P(Peer-to-Peer)网络是一种新型的不依赖于集中式服务器的分布式网络模型。将P2P技术应用于身份验证服务,使系统在节点间分配来自用户的身份验证请求。首先提出在节点上采用Agent技术进行身份验证和证书管理,并在系统中引入信任机制来优先选择邻居节点和评价信息质量。然后介绍了身份验证系统的结构和用户访问本系统的实例,最后讨论了系统的通信方式。

Authentication System Based on P2P Technology

P2P network is a new kind of distributed network which does not depend on centralized server.This paper applies P2P technology to the authentication services for the purpose of distributing authentication request among the nodes.It firstly proposes the utilization of agent technology on the nodes during authentication and certificate management,and the introduction of trust mechanism into the system to choose neighboring nodes and judge the information quality.Secondly,the paper introduces the structure of authentication system and an example of users' access to this system,and finally discusses the communicating methods of the system.
