In P2P systems, every user can release files freely, which makes the large-scale file-sharing feasible. However, with malicious nodes increasing, lots of faked files and deceptive behaviors restrict the development of P2P application. Current P2P trust models can’t guarantee the Quality of Service(QoS), and take no consideration for trust decay and cooperative cheat. To address these problems, this paper presents a novel behavior-based P2P trust model. The direct trust and reputation trust are considered, and the time decay function and reputation adjustment factor are provided in the model. Results of simulations show that compared to the current trust models, the proposed model is more efficient and scalable.
