企业应用系统整合中的CAS单点登录技术

针对企业应用系统单点登录的需要,提出一种基于中央认证服务器(CAS)的单点登录技术方案.系统中,认证管理器通过责任链模式管理认证执行者,客户端浏览器与认证服务器之间采用HTTPS协议,认证服务器与平台应用服务器之间采用HTTP协议.在访问业务系统时,相关信息的传递均结合时间戳、关键信息加密签名和SSL加密通道技术.在自动认证完成后,业务系统可根据需要设定是否继续走安全套接层协议(SSL)加密通道,既保证单点登录过程中信息传递的保密性和真实性.又兼顾业务系统访问的安全与效率.

CAS Single Sign-On Technology for Integration of Enterprise's Application System

In order to meet the single sign-on needs of the enterprise's application system,we propose a center authentication server(CAS)-based single sign on solution to integrate the Web applications.In the system,an authentication manager is given to manage the authentication executives through responsibility chain pattern,HTTP protocol is used for the communication between client browser and authentication server,and the communication between authentication server and application server;any information passing is...
