| 摘 要： | 针对分布式点对点(P2P)网络中的信任管理问题,提出了一种多维度的信任管理机制。它运用直接信任评估和间接信任评估方法,依据各用户的行为来判定系统中用户的可信任程度,从而避免因为恶意用户的恶意反馈对网络造成的负面影响。在Bad Mouthing和on-off攻击场景下与EigenTrust方法进行对比,所提出的方法取得了较好的有效传输率(SRT),表明该机制能够有效地抑制恶意用户的行为。

| Abstract: | Concernig the trust management in Peer-to-Peer (P2P) networks, a multi-dimensional trust management mechanism was put forward.It utilized direct and indirect trust evaluation methods to determine the trust degree of trusted users in the system according to each user's behavior, so as to prevent malicious users from the negative impact caused by malicious feedback on the network. Compared with the EigenTrust in Bad Mouthing and on-off attack scenarios, the proposed method got a higher Success Rate of Transmission (SRT). The simulation results show that the mechanism can effectively inhibit the malicious user behavior. |
