电子签章系统的研究与实现

电子签章是企业进行权限管理和保证信息系统安全的一个必须解决的重要问题。结合研发电子签章系统的实践,详细论述了开发电子签章系统中的几个关键技术,包括系统的体系结构、中间件技术、哈希算法、电子签章完整性策略、远程用户登录技术、电子文档完整性策略及数字签名等几个方面,开发了具有自主知识产权的基于W eb的电子签章系统,实现了电子文档的真实性、完整性、机密性和不可否认性,最后给出了应用实例。通过在两种型号的飞机研制中的应用,说明该系统的开发是成功的。

On Implementation of an Electronic Seal System

It is essential that enterprises have electronic seal to enforce their power and assure the safety of their information systems.In the paper we expound some key techniques for the development of an electronic seal system,including system architecture,middleware,HASH algorithm,electronic seal integrity strategy,remote user login technology,electronic document integrity strategy,and digital signature etc.We develop a web-based electronic seal system of our own intellectual property rights which guarantees its genuineness,integrity,confidentiality and undeniability.The system is successfully applied to the R&D of two models of aircraft in Hongdu Group Company of Aeronautical Industry,Nanchang,indicating that the system development is successful.
