Structured Topology for Trust in P2P Network

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 the 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 trust management in portable P2P network based on DHT (discrete hash table) is proposed. In which includes trust management strategies and peer operations on certain DHT circle. Effectiveness and practicality of the proposed structured topology have been showed in simulation experiments at the end.
