中文摘要: 单点登录是解决网络环境下门户系统安全认证的一种有效策略。在分析Central Authentication Service (CAS)的体系结构、认证流程的基础上，对CAS进行了扩展，把粗粒度的角色权限管理机制引入到CAS中，提出了粗粒度、松耦合的基于角色权限管理的CAS。使CAS不仅能快速完成统一身份认证，而且还具有权限控制功能,从而提高了整个系统的可用性与安全性。
Abstract:Single Sign-On (SSO) is an efficient and secure authentication solution for portal system. This paper analyses the architecture and authentication process of CAS. By extending the CAS, a mechanism of coarse-grained Role Based Access Control is added to CAS. This paper proposes a new model of CAS, which has a coarse-grained and loosely-coupled Role Based Access Control. The extended CAS cannot be used for authentication, but can also be used for authorization, which increases availability and heighters the security of the system.
