摘　　要：在网格环境中,针对不同管理域之间的资源共享和协同,提出了一种基于行为的信任模型,模型采用了分层和实体自主信任的思想,不同层次维护相应的信任表格,并体现出实体动态的主体特性。分析和仿真表明,基于行为信任的分层实体自主信任模型在有效性和算法复杂度方面显示出较好的性能,是对网格信任模型的有效补充。A trust model based on behaviors is proposed to achieve the share and cooperation of the resources among different domains in grid environment.The model adopts the ideas of hierarchical and entity self-determined trust.Different hierarchies maintenance the trust tables respectively,moreover the dynamic and subjective characteristics of entitys are exhibited in the model.A preferable performance in availability and algorithm complexity of the model is indicated through analysis and simulation;and it is the efficient supplement to trust models in grid.
