摘要

信任模型已成为网络安全研究的热点.结合模糊集合理论在网格环境下重新给出了信任的描述机制.在信任的综合评判中

融入中间推荐节点的直接交互经验

充分体现了主观因素的重要性.鉴于信任的动态性

结合时间衰减和路径衰减两因素给出了新的信任更新模型.实验结果显示了模型的准确性和健壮性.相信该模型的提出能为信任模型的进一步研究起推动作用.

Abstract

Trust model has become the focus of network security.The description of trust is given newly with fuzzy set theory for grid environment.In course of trust synthesis evaluation

direct interaction information of the middle recommendation node is presented

which expresses the importance of subjective factor.According to the dynamic character of trust

a new model of trust renewal is provided

which is based on the two factors of time-attenuation and path-attenuation.Experimental results show that the model is exact and robust.It can impel the further research of trust model.
