Adaptive P2P trust aggregation method for resisting collusion attack
P2P环境下抗共谋攻击的自适应信任反馈聚合方法

Aiming at the lack of existing trust management model in resisting the collusion-attacks, this paper designed a dynamic adaptive trust aggregation method. According to the degree of concentration of the data, after problem-transformation with bipartite network projection, this method could automatically adjust the parameters and filter the data carrying trust feedback. The simulation results show that this method enhances the trust management model for the resilience of the collusion attack, to ensure the robustness of the model in the trust aggregation stage.
