“…Besides the studies for the reputation based trust model, some researchers have studied the security mechanism of the reputation information management related tightly with the trust model. Reference [8] provides an enhanced security transmission protocol for trust management. It uses random numbers to suppress the replay attack, and utilizes digital signature algorithm to assure the integrity and consistency of reputation information.…”

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.

“…However, most of them do not take security into consideration by design [1] and simply assume all peers act normally in the system according to the protocol. Due to open and anonymous characteristics, this assumption does not hold true.…”

Almost all of reputation systems for P2P applications are purely decentralized, trust management is complicated and convergence speed of trust in node is slow; even in most of them cost of network is overwhelming due to adopt broadcast searching mechanism. We present a partially decentralized timesensitive reputation management model that has several advantages. Trust evaluator can define the valid period of trust evaluation based on own desire; Reputation system is efficient, convergence speed of trust is fast; Peers can receive more and better services; Furthermore it is scalable: network overhead is low; trust management is simple.
