【摘要】 现有服务选择模型仅计算信任和不信任条件下的信任度且计算比较复杂,针对此问题,借助云理论的定性定量互换模型,提出云理论信任服务选择模型,给出普适计算服务选择中信任云的计算、评估和更新方法。该信任模型计算简单,可以较好地表达信任的不确定性、提高网络平均信任密度和合作成功率,减少网络欺骗。更多还原

【Abstract】 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.更多还原
