摘要
分析了分布式环境中信任的特点,总结了目前PKI体制中实体信任的缺陷,介绍了信任度机制以及信任路径中的两种独立路径-不相交路径和连通路径。结合图论中的最可靠路径算法,提出了一种PKI信任度模型中优化的可靠路径算法,提高了信任的准确性。
The trust's peculiarity in the distributed system is analyzed,the shortcoming of trust model in Public Key Infrastructure(PKI) is summarized,and the trust valuation mechanism,two notions of path independence-disjoint paths and connective paths are presented.Based on the most reliable path algorithm in graph theory,it proposes an optimization algorithm to improve the accuracy of trust relationship in the Public Key Infrastructure.
