Security Framework Based on Reputation Mechanism for Peer-To-Peer Systems

Peer-to-peer networks have emerged over the past several years as a new and effective way for distributed resources to communicate and cooperate. Peer-to-peer computing is the sharing of computer resources and services by direct system exchange. These information sharing environments are increasi...
