摘　　要：针对传统网格信任模型中倾向于资源使用者抉择资源而忽略资源提供者的抉择这一现象,分析了信任关系具有的特性,建立了基于域的对等信任模型,并提出了一种更能充分发挥网格资源效率的对等信任机制。该机制认为网格的实体具有资源使用阈值和资源提供阈值,网格实体在进行资源的共享和协同时,交互双方在使用资源和提供资源方面都需要根据相应的阈值抉择匹配的信任度,并通过推荐信任链路建立对等信任关系。The traditional grid trust model tends to focus on the choice of resource users and ignors the suppliers. The characteristics of trust relation are analyzed, a P2P trust model based on domains is built, and a P2P trust mechanism is put forward, which can adequately exert the efficiency of grid resources. In the mechanism we think that the entity of grid has the resources usage threshold value and resources provision threshold value. During resource sharing and collaboration by grid entity, both communicative sides select matching trustworthiness on resource using and supplying, according to their specific threshold value. Finally P2P trust relation will be built up through the recommending trust network.
