PMI中的证书路径处理机制的优化

Certificate Path Processing Mechanism Opimizing Design in PMI

在PMI中,证书路径的处理包含属性证书路径处理及各属性证书相对应的公钥证书路径的处理。其中证书路径构造尤为复杂和耗时,路径验证算法也没有考虑顺序,缺乏相应性能分析,阻碍了PMI的应用推广。提出一种优化的路径处理方案,给出了实现的流程图和算法,并进行了性能分析。

Certificate path processing includes the attribute certification and their corresponding public key certification path processing in PMI. The certificate path construction is more time-consuming and complicated among the path construction and path validation, and the algorithm for path validation is lack of efficiency analysis and takes no account of the order that it baffle the popularization of PMI. An optimizing design for the certification path processing is given, and offer a realized flow chart as well as algorithm, in the end the efficiency analysis is presented.
