Abstract

Recently, cross-disciplinary efforts involving economics and computer security have proliferated. And Peer-to-Peer (P2P) reputation systems are essential to evaluate the trustworthiness of participating peers and to combat the selfish, dishonest and malicious behaviors of peers. But reputation feedback is special kind of information, and it is not free. Based on those above consideration, in this paper, VCG (Vickrey-Clarke-Groves)-like reputation remuneration scheme inspired by economic model is proposed to stimulate rational peers not only to provide reputation feedback, but truthfully offer feedback.
