摘要
文章基于国外电子商务管理解决方案的一般框架,针对当前电子政务发展中存在的主客观方面的主要安全问题,对电子政务的网络结构及安全认证方案进行了探讨;对数字证书服务进行了研究;对数字证书、CA树、证书链、可信数字证书等概念及数据结构作了形式化的定义,推导出了证书链的性质、判别证书链中可信数字证书的命题并加以证明。采用面向对象的建模方法建立了数字证书、签名者、证书链的对象模型。
The network infrastructure and secure authentication scheme ,based upon the general framework of oversea e-Government administration solutions,are discussed firstly in this paper,which aims at the major security subjective and objective problems during the development of eGovernment.Then,the study on the services of digital certificate is pre-sented.The concepts and data structures of digital certificate,CA tree,certificate chain,and trusted certificate are formally defined.The properties of certificate chain and the thermos to determine the trusted certificate in certificate chain are also derived and proofed.Finally,the OO model of certificate,signed,and certificate chain are established by adopting the OO modeling method.
