信任模型是P2P应用研究中的一个重要课题.最近的研究发现P2P信任模型存在一些很难解决的问题.本文总结了目前P2P信任模型领域的主要算法,重点分析了其中的主要研究问题,概括了P2P信任算法研究中主要使用的评价方法,对其相关研究问题进行了讨论,对未来的研究作了展望.
Trust model is an important research topic for the P2P application. Recent research shows some intrinsic limitation in P2P trust model is proposed. In this article we discuss and classify some major algorithms proposed for trust model. The fun- damental problems in trust model research are identified and the metrics for evaluation of trust model algorithms are summarized. Some topics are also discussed for their close relationship with trust model research. Finally, some possible directions for future research are discussed.
