Secure Routing in Structured Peer to Peer File-Sharing Networks

Structured P2P protocols have recently become the ultimate solution in creating large-scale distributed networks, because they provide a powerful platform for providing various decentralized services. Structured P2P protocols have created file sharing networks with high fault tolerance, but still lack security in routing. Messages can still be corrupted, incorrectly routed, and can be responded by illegitimate nodes. Because of their decentralized characteristics insecure routing can destroy the networks´ integrity. This paper studies attacks aimed at correct routing in structured P2P file sharing networks and presents techniques for defenses against them. This paper will fully describe and prove the validation of these techniques and evaluate them in the end.
