摘要
信任机制已经被广泛地应用于网格计算。基于网格节点对于资源提供的反馈评价,提出了一种基于Dempster-Shafer证据理论的网格信任模型。该模型给出信任函数、似然函数、信任损失的表示方法,并在此基础上建立了对于资源提供者的信任监测机制及防止资源使用者共同串谋与诋毁的方法。
Trust management mechanism is widely used in the Grid computing. This paper proposes a trust model based on D-S theory based on the feedbacks of given by resources users to providers. The definition of belief function, likelihood function, and benefit lost. The new trust model provides the monitor mechanism to resources providers and the mechanism for preventing collusion and bad--mouthing.
