Secure Reputation Framework for BitTorrent

With the proliferation of the use of Internet 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 framework for reputation in BitTorrent. Our framework allows peers to securely share their opinions (votes) about a peer after a transaction, then securely retrieve this information when required by another peer.
