Trust Model of P2P Network Based on Fuzzy Degree of Credit

Article Preview

Abstract:

At present P2P is widely applied on the Internet. But it still has a safety hazard because of the special feature of dynamic and anonymity of P2P.This paper designs a model of P2P trust based on fuzzy degree of nodes' credit. It computes the fuzzy degree of nodes' credit according to the historic records and the theory of fuzzy mathematics, and the result is used as the basis of choice of P2P transaction. The fuzzy degree of nodes' credit will be increased and decreased according to the behavior of the node, establishing the dynamic and reasonable mechanism of rewards and punishment. Experimental results show that the model designed in this paper has a better performance in the parts of trade success rate and network load.
