Abstract

Reputation based trust management is increasingly popular in providing a quantitative measurement for peers choosing reliable resources and trusted cooperators in a decentralized Peer-to-Peer (P2P) environment. However, existing approaches do little regarding the validation of a peer's reputation, that is, it is challenging to guarantee the validation and accuracy of computing a reputation value due to malicious denigration or overpraising. In this work, we first investigate the impact of this problem. We then propose TruthRep approach, which encourages peers to provide honest feedback by involving the quality of their evaluations of others into computing reputations. We outline the challenging issues of this design, and present preliminary experimental results.
