摘要
研究网络管理,提高网络质量,鉴于现有的P2P网络推荐信任机制缺少完整的系统解决方案,结合局部信任机制的特点,依据在P2P网络中对相关的节点的评价能力及历史信息的搜集、分析,并加强安全性管理,提出一种基于推荐的P2P网络信任管理模型。在信息的收集过程中,仅限于与某节点有过交易历史并有较高成功经验的节点或与节点有关的信息,并且有机融合节点特征,建立了综合评判机制,分析了网络中存在的恶意行为及对恶意行为的抑制方法。仿真实验表明模型的可信性和实用性,可以有效地减少恶意节点的破坏,提高P2P网络的整体安全性能。
In view of the trust mechanism based on recommendation in P2P network is short of a complete system solution,combined the characteristics of local trust mechanism,and according to the evaluation ability and the collecting and analyzing of the historic information related to the nodes,the paper proposed a trust model based on recommendation on P2P network.In the model,the node＇s trust value composed by direct transactions trust value and recommendation trust value are defined.In the information collection process,the collection of information is limited to the nodes which had transaction history wich other nodes and had high successful experience,the characteristics of these nodes are integrated,a comprehensive evaluation mechanism is established,and malicious acts in the network and method of suppression of malicious acts are analyzed.Simulation results show that the model is effective and credible.It can relieve the negative influence of recommendation from malicious nodes,and improve the overall performance in P2P network.
