| 摘 要： | 借鉴确定性理论中的不确定推理,提出了一种新的P2P系统信任模型。该模型根据节点的历史交易情况,运用C-F模型计算节点的可信度,节点依据计算结果与可信度高的节点进行交易,在节点间建立信任关系。分析及仿真表明该模型能有效地隔离恶意节点,提高交易成功率。

| Abstract: | This paper presents a novel global trust model based on confirmation theory. The reputation is calculated by C-F model according to the bartering history, and then the peer decides to download the sharing file from which the peer has good reputation. Analyses and simulations show that the model can discard the malicious peer from peer-to-peer system effectively and improve the rate of successful barter greatly. |

| Keywords: | peer-to-peer network confirmation theory reputation recommend |
