摘要： 针对分布式环境下信任管理的不确定性，在基于角色的信任管理基础上，引入行为感知的分析方法，以此作为信任评价的依据。将行为对信任域的影响量化为固定区间内的信任值，通过统计用户群的累积行为，计算出角色声望和域声望，并反馈调整信任域之间的信任委托关系。静态角色和动态行为的结合有效地增强了分布式网络的信任保障能力。

Abstract: Aiming at the uncertainty of trust management in the distributed environment, this paper introduces behavior aware analytical method into role based trust management for trust evaluation. The impact of behaviors on trust domain is quantized to trust value in a fixed interval. Role and domain reputation are calculated through statistics of cumulative behaviors of user groups, as feedback to adjust trust delegation between domains. The combination of static role and dynamic behavior will effectively enhance security in distributed networks.
