网络服务系统统一身份认证模型的研究与设计

Internet上服务的增多带来了用户信息管理的各种问题,每个服务商都要维护庞大的用户信息库;用户也要重复提供认证信息以使用不同的服务.本文提出了一个统一身份认证模型,可以实现安全、可靠、高效的用户身份认证.文章先给出设计此身份认证模型的必要性,介绍并分析了当前流行的身份认证机制的特点和性能,然后提出了此统一身份认证模型的结构,并对其能实现的功能做了介绍,最后给出了一个安全、高效的身份认证算法和一个可靠、严谨的身份联合算法.

The Study and Design of Universal Identity Authentication Model of Internet Service System

The ever increasing Internet applications bring many problems of managing user information. Every service provider must maintain a large information database , and users must provide different evidences for different services. This paper proposes a universal model for authentication. The model can achieve the goal of providing a secure, reliable, efficient authentication. At first , the article gives the necessity of the model, and analyses the features and capability of some popular mechanisms of authentication. And then it proposes the structure of the universal model ,introduces some functions it can accomplish. At last , a secure, efficient authentication algorithm and a reliable, closeknit identity alliance algorithm are proposed.
