对等网络环境下的信任机制是作为一种新颖的安全问题解决方案被引入的,基本思想是让交易参与方在交易完成后相互评价,根据对某个参与方(主体)的所有评价信息,计算该主体的信任度,为对等网络中其他主体以后选择交易对象时提供参考.文中介绍了对等网络环境下信任的基本定义.深入剖析了信任机制与网络安全的关系,并讨论了信任机制的体系结构.根据信任机制研究的内容分别归纳总结了信任模型和信任推理方法的最新研究成果,并选取典型的信任模型进行了评述.最后探讨了目前研究中存在的问题,并展望了需要进一步研究的方向.
對等網絡環境下的信任機製是作為一種新穎的安全問題解決方案被引入的,基本思想是讓交易參與方在交易完成後相互評價,根據對某箇參與方(主體)的所有評價信息,計算該主體的信任度,為對等網絡中其他主體以後選擇交易對象時提供參攷.文中介紹瞭對等網絡環境下信任的基本定義.深入剖析瞭信任機製與網絡安全的關繫,併討論瞭信任機製的體繫結構.根據信任機製研究的內容分彆歸納總結瞭信任模型和信任推理方法的最新研究成果,併選取典型的信任模型進行瞭評述.最後探討瞭目前研究中存在的問題,併展望瞭需要進一步研究的方嚮.

The trust mechanism for peer-to-peer(P2P)network had been proposed as a promising methodology to handle the complex security problems.The basic idea of the trust mechanism for P2P network is to let parties rate each other after the completion of a transaction,and use the aggregated ratings of a given party to derive a trust score,which can assist other parties in deciding whether or not to transact with that party in the future.In this paper,firstly the concepts of trust mechanism existing in the P2P network are summarized and presented.Secondly the relationship between trust mechanism and network security is analyzed and the framework of trust system is discussed.Thirdly the latest techniques on trust model and trust inference method are summarized respectively.Finally several typical trust model systems and their mathematical inference methods are described in details.The current problems of trust mechanism for P2P network and research trends in this area are also discussed.
