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.
