Emerging peer-to-peer services such as Freenet, Gnutella, Kazaa, and Napster provide an easy and efficient way to share resources and information. However, misuse or unfair exploitation of resources by users that cannot be trusted has been reported. Trustworthy schemes of peer-to-peer systems are greatly needed. In this paper, a new group management approach to improve trustworthy in peer-to-peer systems, called “Kaliphimos” is proposed. Kaliphimos is an overlay, multidimensional reputation infrastructure for peer-to-peer systems. This trustworthy group management scheme includes algorithms for group member insertion, deletion, merging, and splitting based on communitylike reputation model.
