摘　　要：提出了一种新颖的信誉管理机制,首先给出了一套客观的信誉跟踪评价标准,然后根据各个节点的能力与行为表现将它们划分成两类:信誉值和能力均很出众的精英节点,一般的或新加入系统的普通节点。精英节点享有一定特权并组成结构化的网络,普通节点组成无结构的网络。接着用一种半全局化的方法来计算和存储各节点的信誉值。最后,通过实验证明此机制的有效性和健壮性。The novel tnxst model for P2P file sharing systems wasintroduced. First, an objective criterion to compute each peer＇s reputation was gaven. Second, based on their values we divided all the peers into 2 parts： one is super peers who share more resources and service and also been given some privileges; the other is normal peers who act normal or new comers, they construct an unstructured network. Third, a semi-global stnlcture for computing and storing the trust value was described. Finally, the experiments show that the feasibility and robustness of this reputation management system.
