基于CAS的单点登录系统的研究与实现

摘要

随着互联网的发展，用户经常需要访问不同系统，这就导致用户需要频繁登录。单点登录就是为解决上述问题而提出的一种技术，它可以使用户只登录某个系统一次即可访问所有相关的应用系统。本文在分析了CAS协议的基本原理后，实现了基于CAS的单点登录系统，为CAS服务器端添加了访问权限控制、缓存层和基于Netty的用户管理系统的功能。%With the development of the Internet,users often need to visit different systems,as a result,they need to login the systems frequently.Single-Sign-On(SSO) is a technology which can handle the problem above,users can lonin one system just once and then they can visit all relative systems without logging in again by using it.In this paper,after analyzing the basic of CAS protocol, SSO system based on CAS with the new functions of access control,cache layer and user administration is implemented.
