Reputation Management Service for Peer-to-Peer Enterprise Architectures

The high potential of P2P infrastructures for enterprise services and applications both on the intranet (e.g. project workgroups) and on the Internet (e.g. B2B exchange) can be fully achieved provided that robust trust and security management systems are made available. This paper presents the reputation system we have devised for our P2P framework which supports secure role-based peergroups and service interactions. Our system includes decentralized trust and security management able to cope with several threats. In the paper the underlying analytical model is presented together with a simulation-based evaluation of the robustness against malicious negative feedbacks

Reputation Management Service for Peer-to-Peer Enterprise Architectures

The high potential of P2P infrastructures for enterprise services and applications both on the intranet (e.g. project workgroups) and on the Internet (e.g. B2B exchange) can be fully achieved provided that robust trust and security management systems are made available. This paper presents the reputation system we have devised for SP2A [1], a P2P framework which supports secure role-based peergroups and service interactions. Our solution includes decentralized trust and security management able to cope with several threats. The underlying analytical model is introduced and discussed, together with a simulation-based evaluation of the robustness against malicious negative feedbacks
