摘要

This paper proposes a time-decay based trust model in peer-to-peer networks. Through the transaction time is faded, the proposed model makes trust value changed dynamically with time decay, which achieves the goal that the more transaction close to, the more reliable it is. Finally this paper presents the experimental protocol and simulation. The experimental result shows that the proposed model is more approached fact value and it can resist vicious association attraction, dynamic strategy attraction, and it has a favorable performance.
