Abstract

In this paper an innovative encryption-free reputation sharing protocol has been proposed for Gnutella-like peer-to-peer network. Instead of using encryption that is hard to be realized in P2P due to the lack of a trust authority, this protocol adopts partition and multi-path methods to transmit the reputation value of a node, which can effectively thwart the man-in-the-middle attack, and protect the integrity of the reputation value during the transmission process in Gnutella-like P2P.
