基于PMI属性证书的匿名认证方案

摘要

随着计算机网络迅速发展，网络交易也越来越普遍，然而在交易过程中，用户身份认证，访问控制及其授权管理成为系统关注的焦点。与此同时，人们对自己的隐私信息更为关注，用户希望通过匿名的方式访问资源。因此，如何实现用户对资源的匿名访问，是一个需要解决的问题。提出了一个基于PMI属性证书的匿名认证方案，实现了对资源的匿名访问。理论分析证明，该方案具有安全性、匿名性和不关联性，可追踪性。%With the rapid development of the computer network,the network transaction is becoming more and more popular, however, in the process of transaction user authentication, access control and its authorized management has become the focus of the system.At the same time, people pay more attention on their own privacy information; users want to access resources through anonymous way. Therefore, how to realize the anonymous access resources is a problem to be solved. This paper proposes a system which based on PMI’ s attribute certificates to realize the anonymous access. Theoretical analysis shows that this solution provides the security, anonymity and no relevance,traceability.
