Trust management evaluates the user trust value of participating nodes in the network based on the past behaviors and satisfaction of sharing resources. However, there also exists security issue even though it has been considered to be safe because malicious user is able to affect the trust management with negative feedback. This paper aims to propose a robust trust management scheme to improve reliability and effectiveness of distributed P2P network by identifying these malicious threats and then limiting the attacker's participation. Especially, our scheme effectively manages for some attacks such as bad mouthing, on-off and sybil. The proposed scheme is expected to effectively protect attacks from malicious peers with improving credibility as well as exactness.
