摘要
针对因特网上网络资源共享中存在的恶意节点行为,提出并描述了一种非结构化对等网络中的信誉管理机制。该机制使用非集中式的策略,根据节点与应用的需求计算节点的信誉度,具有独立性,不需要其它节点的参入与辅助。把加入对等网络的节点行为划分为恶意行为与友好行为,既可以统计节点对系统的贡献,也可以根据恶意行为而减少节点的信誉度。描述了信誉管理机制的设计与实现,各种节点行为下的仿真实验结果表明,该信誉管理机制是对等网络中一种真实的、高效的、信誉机制良好的资源共享策略。
Confronted with the various types of malicious intrusions in P2P based resource sharing system over the Intemet, a novel reputation management mechanism in unstructured P2P network,,; is presented and described. A decentralized approach is adopted which allows to compute peers＇ reputation based on the traffic between a node and its neighbor peers. The behavior of a peer is divided into two actions and distinguished with bad and good actions respectively： The design and implementation of this reputation-based model is also discussed subsequently. The experimental results obtained from simulations show that the fairness reputation mechanisms is a feasible, efficient and good policy in P2P-based resource sharing systems.
