A scheme of trust management system for P2P network

P2P network has become an important branch of Internet recently, with the significant advantages of full resource utilization, dynamics, openness and high scalable, which helps it achieve wide applications. But security and trust have also become urgent problems for a P2P network due to its openness and anonymousness. Most of the current schemes rely on some trust models, but the research in systematic managing scheme is scarce. Consequently, we propose a scheme of constructing trust management systems in a P2P network here.
