Trust Model Based on Cloud Theory in Pervasive Environment
Weijie Wang · Jisuanji gongcheng · 2010
Aiming at the problems of the existing service selections,such as only computing trust values under the condition of trust and distrust,and computation complexity,in virtue of transforming model between qualitative concepts and their quantitative expressions,this paper puts forward service selection based on cloud theory trust model,and presents the method of trust cloud computing,evaluation and updating.This model can express the uncertainty of trust well.It improves the average of network trust density and the cooperation success probability,and reduces network deceive effectively.
