| 摘 要： | 随着P2P(peer to peer)系统得到日益广泛的使用,其面临的服务欺骗和节点资源滥用等可信问题也越来越严重.传统的安全方案已经不能适应这种需求,基于信誉的信任模型为解决这类问题提供了一种新的思路.分析了信任与信誉的关系,给出了一种基于信誉的信任模型的基本运行框架,对当前典型的基于信誉的信任模型进行了综述与评论,并对这些模型进行了比较分析.最后讨论了当前研究存在的问题,并对未来的研究方向作了展望.

| Abstract: | The more along with the wide application of P2P system,the more it will face some severe trust problems such as service faking and resource abusing by some malicious peers.The conventional security measures cannot be used to cater for this demand,whereas the reputation based trust model has given a key to them.Firstly,the relationship between trust and reputation was analyzed,and a basic running framework for the reputation based trust model was put forward.And then the overview and comparison for current c... |
