P2P文件共享系统中Peer的行为评价

以节点的行为评价是信任研究的基础为切入点,在严格遵循纯P2P系统信任机制建立的限制条件的基础上,综合运用表现序列和概率统计中即时估计、总体估计等数学理论知识,最终提出了对P2P共享文件系统中的Peer行为的一套评价预测方法.分析表明,该方法产生的误差在允许范围内.从而,能够为P2P系统准确、广泛、长时间的得到应用提供良好、完备的信任机制.

Evaluation of behavior of Peers in Peer-to-Peer file sharing systems

Started with the research of evaluation of the behavior of peer is fundamental to the research about trust,basing on being strict to the limitation of P2P system established,this paper classifies the behaviors of peer and also puts forward a set of evaluating and forecasting means of the behavior of peer in the Peer-to-Peer file sharing systems by comprehensively using some mathematical tools,such as representation sequence,instant estimation and overall estimation in probability statistics,etc.The analysis results showed that the scheme of this method generates the error are in the accepted range.And it will provide the favorable and self-contained trust mechanism for the right,abroad and longtime application to the P2P system.
