基于信任迭代的P2P网络信任管理模型
Trust Management Model of P2P Network Based on Trust Iteration
摘要
Abstract
Most trust management models can not accurately calculate the recommendation trust value in P2P networks, and the nodes can not effectively prevent malicious recommendation in transaction process. Aiming at these problems, a trust management model based on trust iteration is proposed. By introducing the conceptions of trust iteration, recommendation credibility and iteration trust value, it utilizes the direct experience to calculate the recommendation trust value between the nodes, divides the recommendation chains into main chains and subordinate chains to reference the recommendation information comprehensively and reduce the influence of deleting recommendation chains, and presents a new iteration method to calculate recommendation trust value, which makes the results more reasonable. Simulation results show that the model can calculate recommendation trust value accurately and restrain the malicious recommendation.关键词
