摘要
公钥基础设施(PKI)是信息安全领域的研究热点。在对现有的信息安全技术进行分析和研究的基础上,提出一种典型的PKI体系结构。通过研究分析PKI在信息传输、信息交换、数据存储、身份验证等方面的应用与实现,解决网络应用中存在信息的真实性、保密性、完整性、可用性和不可抵赖性等安全问题。同时讨论了限制PKI应用的环境因素和在多个独立的PKI系统实现过程中需解决的问题。
Public key infrastructure （PKI） is a research focus of the field of information security, On the basis of analyzing and researching to the existing information security technology, the paper puts forward a kind of typical PKI architecture. Through researching and analyzing application and realization of PKI in information transmission, information exchange, data storage, authentication, etc, it solves the security problems of information authenticity, confidentiality, integrity, availability, non-repudiation and so on which exist in network application. And it discusses the environmental factor of restraining PKI applications and needing to solve problems while a lot of independent PKI systems realize.
