摘　　要：针对现有P2P网络中存在的欺诈、摇摆等安全性问题,提出一种新的信任评价模型。综合考虑不同交易因素对节点信任值的影响,引入惩罚机制防止节点反复实施恶意行为,同时引入奖励因子,激励节点的诚信交易。设立交易限制额,并讨论了其与信任阈值的关系。实验表明该信任模型能有效地防止节点的恶意行为,降低交易的风险。Aiming at the security problems such as the fraud and swinging in existing P2P networks, we put forward a new trust evaluation model. Comprehensively considering the impact of different transaction factors on the trust value of the nodes, we introduce punishment mechanism into the model to prevent the repeated malicious behaviours of the nodes, and the reward factor is also introduced at the same time to encourage the integrity of the nodes in transactions. We also set up the amount of transaction limits, and discuss its relationship with the trust threshold value. Experiment shows that the trust model can effectively prevent the nodes from malicious behaviours, and reduce the risk of transaction.
