基于云模型和风险评估的信任模型研究
Research of Trust Model Based on Cloud Model and Risk Evaluation
摘要
Abstract
Aiming at the problems of lacking credibility evaluation for the feedback information and risk assessment in trust model based on cloud theory, this paper proposes a new trust model. The credibility of an evaluation is measured by combining the evaluation number and evaluation consistency about a feedback entity. Trust cloud for an entity is generated based on the weighted backward cloud generator algorithm. Risk value is assessed according to entity's active degree and the numerical characteristics of the entity's trust cloud. Simulation results indicate that the model can reflect the behavior characteristics of every entity accurately, and the success rate of interaction between entities is significantly improved.关键词
