Computing and Routing for Trust in Structured P2P Network

Abstract

Study of trust in P2P network now is focus on how to effectively against various malicious behaviors such as providing fake or misleading feedback about other peers and the management of trust in a P2P environment. But the scotoma of portability that trust peer can join (leave) a certain P2P network at anytime and anywhere is seldom discussed. In this paper, a structured topology for trusts management in portable P2P network based on DHT (discrete hash table) is proposed first, in which includes trust management strategies and peer operations on certain DHT circle. After that, a novel trust-computing model for the structured P2P network and the main trust decisions in the structured network are introduced too. Effectiveness and practicality of the proposed trust management have been showed in simulation experiments at the end.
