Ensuring Trustworthy File Sharing in Decentralized Peer to Peer Networking

S. Umamaheswari, Arun M. Kudtarkar, Dr. T. Hamsapriya, R. Mekala


The openness of P2P network gives a perfect situation for attackers to spread malicious content in the network. In this paper we investigate the design of a secured Information-Sharing Incentive Scheme (ISIS) for decentralized peer-to-peer network (P2P) to ensure trustworthy file sharing. The dynamically growing ISIS increases the efficiency of a P2P network by means of minimal malicious peers and malicious files by establishing trust among good peers as well as identifying and isolating the malicious peers. The ISIS is robust, predictive and invariant under varying network conditions and peer resource constraints.
