Abstract
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 trust management models, and demonstrates more
robustness and effectiveness.
