摘要： 针对P2P节点的匿名性和隐蔽性易导致恶意节点滋生的问题,基于社会网络的一些基本理论,提出了一种新的P2P分布式信任模型MFTrust.提出了涉及时间因子、通信成功率因子、通信频率因子和评价的局部信任度模型和全局信任模型;设计了节点通信历史相关性因子,针对全局信任度提出了相关性信任度模型.仿真分析表明,MFTrust模型具有快的信任收敛速度,在路由过程中能有效区分恶意节点.

Abstract: To solve the problem that the anonymity and concealment of P2P nodes are liable to bring on vicious nodes, a new distributed trust model named MFTrust was developed on some social network principles for P2P networks. Both global and local trust models were developed involving such multidimensional factors as time, measure of success in transmission transmitting frequency and appraisals for relevant nodes. Designing the historical correlation factor of communication between nodes and based on the global trustiness, a correlation trust model was developed. Simulative analysis showed that the MFTrust model is quicker at trust convergence rate than conventional local and global trust models and available to distinguish the attack from vicious nodes effectively during routing.
