Abstract: To improve the security and success rate of transaction in P2P network and show the ambiguity and randomicity of the trust objectively,a trust evaluation model is proposed base on cloud model theory.By created definition of the trust cloud and digital properties,the qualitative description and quantitative representation of trust is unified.In order to obtain more complete trust information,comprehensive trust cloud is realized based on algorithm of converse trust cloud generator and trust merging,and by calculating the uncertainty of trust to choose recommend node,which improve the reliability of recommendation.Using algorithm of similarity,trust comprehensive trust evaluation is generate,which realizes Decision-making of trust as reference and accordance of a trade node.Through simulation experiment show that the method can reflect the level of trust between P2P nodes Objective and truly,which provide Scientific and effective foundation for successful trading between nodes.
