Trust management model based on Shapley entropy
基于Shapley熵的主观信任模型

Aiming at the features of subjectivity and uncertainty of trust in open network, this paper proposed a new subject comprehensive trust management model based on Shapley entropy. This model computed the direct trust value using fuzzy comprehensive evaluation method, and introduced the conception of Shapley entropy to calculate the recommendation trust value based on similarity of evaluating tendency, uncertainty of evaluation feedback and reliability of recommendation nodes, in order to manifest the subjectivity of evaluation while guaranteeing the security of transactions. Simulation results show that the model can calculate trust value accurately and ensure the success rate of interaction effectively.
