基于身份认证技术的系统数据安全保障方案探讨

身份认证是实现授权访问的基础，授权访问机制保障了应用系统访问的安全性，单点登录是为解决传统认证方式中存在的缺陷而提出的一项技术。本文介绍了统一身份认证中单点登录技术的概念和应用特点，提出了针对系统数据的安全问题，通过对Microsoft．Net Passport和Liberty两个单点登录标准的分析，提供了相应的保障方案和解决思路。

Study of System Data Security Program Based-on Identity Authentication Technology

Identity authentication is the basis for the realization of authorized-access, the mechanisms of authorized-access to protect application security, and single sign-on（SSO） is the way to resolve the existing problems of traditional authentication. First, introduced the idea and point of SSO in uniform identity authentication. Second, raised security issues for system data. Final, provided the corresponding security programs and ideas to solve specific problems by analysis of Microsoft .Net Passport and the Liberty SSO-two-standard.
