摘　　要：研究当前信任管理中的信任传递与信任聚合问题,提出了信任传递与信任聚合应遵循的规则.以Jφsang信任模型为例,分析其信任传递与聚合方法的不足,进而提出了新的信任传递方法和信任聚合方法.分别通过实验和例子与Jφsang的信任传递和聚合方法进行了对比,结果表明,新信任传递方法更具一般性,而新信任聚合方法更满足信任聚合的规则.Trust transitivity and aggregation of trust management are studied, and trust transitivity and aggregation rules are presented. Shortcomings of trust transitivity and trust aggregation methods in Jφsang ＇ s trust model are presented. A new trust transitivity approach is proposed for trust transitivity, and an approach is provided for trust aggregation. By the experiments and examples of the comparision of Josang＇s approach and aggregation method, the new trust transitivity approach is more general, and the new trust aggregation approach satisfies the rules of trust aggregation.
