P2P环境下基于模糊理论的Dirichlet信任评估模型
Dirichlet trust rating model based on fuzzy theory for P2P network
摘要
Abstract
A Dirichlet trust rating model based on fuzzy theory is proposed to deal with the phenomenon of malicious eval-uation and swing service in P2P network. The model proposed uses fuzzy clustering to isolate the malicious evaluation, and also reduces the probability of swing service. Considering the dynamic character of subjective trust, a new mechanism of trust renewal is provided, which is based on the degree of approximation in fuzzy theory. And this mechanism does bet-ter in improving the enthusiasm of service provider to provide quality services. Several related experiments show that the model has several good characters for the trust rating in P2P network.关键词
