公钥基础结构中的信任度

Confidence in Public-key Infrastructure

分布式系统和电子商务的安全以公钥基础结构 ( PKI)为基础 ,为实现信息的安全交换 ,用户可从 PKI中得到另一用户的公钥及其证书。给出 PKI中一种新的估算各认证服务中心之间信任度的方法并说明其合理性 ;对有多条证书路径的 2个认证服务中心之间的信任度进行敏感性分析 ,得出了有效的信任度估算策略。

A public key infrastructure (PKI) is a prerequisite for security in distributed systems and for electronic commerce.For secure communication,an user can get another user's public key from PKI.A new method for evaluating the confidence of certificate authentication centers in public key infrastructure and its rationality are presented.It also gives the sensitive analysis of confidence between two certificate authentication centers, which have several certificate paths and some useful conclusions.
