摘要： 利用数据加密技术，实施一种基于挑战/应答方式的安全身份认证。并在该身份认证的基础上，开发出针对园区网环境的网络应用单点登录系统。园区网用户可通过该系统访问注册过的各项B/S 和C/S 网络应用，且效率和安全性都得到了更大的提升和保证。

Abstract: A sort of secure authentication based on challenge/response mode is implemented by means of data encryption techniques. Also, multi-application but single-logon system is developed in the Intranet environment. Through this system, Intranet users may access all the network services which have been registered previously with perfect efficiency and security
