摘要
在一个面向服务的网格结构中,服务之间的信任关系很难建立,这是因为一方面要支持单次登录机制(SSO);另一方面还要支持大量的动态临时服务信任的交互,源端和目的端不可能提前建立信任关系,这样源端无法提前评估对目的的信任,因此应该研究评估S对T信任的解决方法。本文基于委托图的传递闭包特点来评估参与者的信任。
Trust is hard to establish in a service-oriented grid architecture.because of the need to support end user single sign-on and dynamic transient service.Trust relation between source and destination cann't be created before.So this paper studies the approach to evaluate trust relation.Based on the transitive closure property of the delegation graph,we give a practical approach to evaluate trust in grid.
