Secure and Distributed P2P Reputation Management

The open, sharing and anonymous nature of peer-to-peer (P2P) network has offered opportunities and threats for the development of distributed computing technology. One feasible way to minimize threats is to establish the reputation-based global trust model. Most of current trust mechanisms are not only unable to restrain effectively such malicious behavior as collusive attacks, but also take no consideration for the security of the trust management. As for these problems, this paper proposes a secure and effective reputation based distributed P2P global trust management model (DSRM), and presents its corresponding distributed storage mechanism of reputation information, and security protection protocol. Theoretical analysis and simulation experiments show that, DSRM has advantages in combating various malicious behaviors such as ordinary malicious behaviors and collusions, and suppressing the sybil attackers and trust information tamper peers in transmission over the current global tru...
