摘　　要：随着网络应用越来越广泛,电子政务系统的敏感信息必须有效地安全保护,然而传统的加密方法不能满足系统的需求。针对当前电子政务系统中存在的安全性问题,文中提出了一种基于三方通信技术的新型电子政务应用系统平台构思,利用三方通信框架中元数据服务器的全局掌控功能,以及采用权能标识构建相应的安全系统,达到消除来自外界安全威胁的目的。同时论述了电子政务系统关于安全性实现方案和技术,以及DES加解密算法,旨在对系统的性能进行优化,以整体提高系统的安全性。With the widespread use of network, the sensitive information in electronic government affairs requires＇ more effective secure protection. However,the traditional method of data encryptioa can＇t completely meet the requirements. In the light of the existing secure problems of electronic government affairs,it puts forward the conception about a new electronic government affairs application platform based on third-party transferring technology, adopts the overall control function of metadata server in the frame of third-party transfer ring, utilizes capability to build the security system, in order to eliminate from outside security threats. At the same time it also discusses the scheme and technique to fulfill the secure SYstems of electronic government affairs and the technology of DES encryption and decryp tion algorithm, aim at optimizing the electronic government affairs system performance to improve overall system security.
