【摘要】 随着计算机科学技术的发展,网络和信息技术已经渗透到社会的各个领域。所以如何保障网络和信息安全问题已成为当前研究的热点,公开密钥基础设施(Public Key Infrastructure,PKI)技术是解决大型开放式网络环境下的信息安全问题最可行、最有效的措施之一。安全支撑平台,是建立在公共密钥基础设施PKI的基础之上,应用数字证书解决网络环境下的身份认证、访问控制、信息保护等问题。本文研究了其中部分问题,首先介绍了密码学基础知识以及PKI的理论基础和基本体系,同时对几种常见PKI信任模型进行了详细的介绍,设计了分布式网络环境下互联互通的安全平台的认证模块和信息加密模块。本文最后总结本文设计的两个模块的不足,并提出了其今后还需要进一步发展的方向。更多还原

【Abstract】 As the development of computer science, network and information technology have already seep through every domains of society. So the problem of how to guarantee networking and information safety has become current hot investigation. Public-key infrastructure is one of the most effective ways to solve the problems of information safety under large open-network environment.The Security Supporting Platform is built on the basis of Public-key infrastructure, and resolve identity authentication, access control, information protection and other issues under the network environment by application of digital certificates. This paper first introduced the basic knowledge of cryptography, as well as the theory and system for PKI, and introduced several common PKI Trust Models in detail. This Paper mainly research on the two major factor of this platform: authentication and encryption.Finally, the author summarizes the shortages of the two modules and points out the future direction of them.更多还原
