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。

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 studied which was based on depth-first traversal.Example and experimental results show that the model and algorithm are feasible and correct.
