摘要: 信任是以网络为媒介的交互主体之间重要决策的依据,为主体处理交互过程中的不确定因素、不可控因素、模糊性和不完备信息等提供新思路。信任管理是描述、建立、验证和维护主体之间信任关系的方法,正日益成为研究热点。首先在分析信任及信任管理相关概念的基础上,给出了信任管理的描述性定义和形式化定义,并讨论了二者的关系;其次,分类对典型的信任管理系统进行分析、点评和对比;最后,总结了当前研究中存在的不足并讨论了信任管理未来的发展趋势。

Next, some typical trust management systems were introduced and compared. Based on the analysis of the shortcomings and problems of the existing trust. gement systems,we ended this paper with discussions on the trend of research and application.
