Abstract

Trust management is very important for participating usersto assess trustworthiness of peers and identify misbehaving peers inthe open P2P environment. In this paper, we present TrustCode, aframework for P2P reputation-based trust management. Leveraging randomnetwork coding, TrustCode spreads coded feedbacks massivelyamong peers, thereby achieving bandwidth-efficient dissemination, ensuringdata availability, and yielding efficient feedback retrieval. Our simulationsshow that TrustCode is resilient to failures and robust againstmalicious nodes. To exhibit applicability of TrustCode, we also presenttwo applications that can be built on top of TrustCode.
