Abstract

The peer-to-peer applications have recently seen an enormous success and spread over the Internet community which showed a dramatic change in the current client-server paradigm; that caused the appearance of some new concepts and protocols. One of the main new concepts introduced is the user anonymity which is in spite of being considered one of the main characteristics of the peer-to-peer paradigm it has introduced a serious security flaw due to the missing of trust between the participants in the system. This paper proposes an approach for peer-to-peer security, where the system participants can establish a trust relationship between each others based on their reputation gained by the participation in the system. The proposed technique relays on the concept of the recommendation cards. This paper discusses this technique and how to apply it to a peer-to-peer file sharing application.
