| 摘 要： | 结合分层思想给出了信任在网格环境下的部署方案,降低了系统的管理成本。基于交互能力和诚实能力提出了细粒度描述的信任模型,增强了模型的合理性,同时探讨了影响信任传播的4种因素,包括循环路径、路径长度限值、节点诚实限值以及进一步信任信息,并在此基础上设计了基于深度遍历的网格信任传播算法。实例和仿真结果表明了模型和算法的可行性和正确性。 |
| 关 键 词： | 网格 信任模型 信任传播 细粒度 |

| Abstract: | A trust deployment scheme based on layered idea was given for grid environment,which reduced the man-agement costs of system.The fine-grain trust model was proposed which was based on interaction capability and honesty ability.It enhanced the rationality of the model.At the same time,4 influencing factors about trust transitivity were dis-cussed,such as cycle path,path length threshold,node honesty threshold and further trust information.On this condition,the trust transitivity algorithm for grid was studie... |
| Keywords: | grid trust model trust transitivity fine-grain |
