Abstract
The P2P system is an anonymous and dynamic system, which offers enormous opportunities, and also presents potential threats and risks. In order to restrain malicious behaviors in P2P system, previous studies try to establish efficient trust models on P2P system. However, most of the trust models use a single trust metric, which can not reflect the practical trust values of the peers effectively. In this paper, we propose a trust model called SFTrust based on a double trust metric. SFTrust separates trust between the service providing and feedbacking. The system is based on the topology adaptation protocol, which was proposed in the unstructured P2P system. Simulation results show that SFTrust can efficiently resist general attacks. Compared with the single trust metric model, our mechanism can take full advantages of all the peers' service abilities for high performance.
