Rabit: A reputation architecture for BitTorrent

With the proliferation of the use of peer-to-peer networks for distributing multimedia and software content, there is an increasing need for efficient and reliable data distribution mechanisms that can scale to large numbers of users. The peer-to-peer protocol BitTorrent is scalable and is widely used to share content. The lack of reputation techniques in BitTorrent makes it impossible to get any information about how reliable a peer is. In this paper, we propose a secure and reliable architecture for reputation in BitTorrent. Our framework allows a peer to securely share its feedback about another peer after a transaction. Then, allow other peers to securely retrieve this information when required. Furthermore, we discuss how secure our system is by studying how it protects against the well knows peer-to-peer attacks.
