The MoR-Trust Distributed Trust Management System: Design and Simulation Results

MoR-Trust is a purely decentralized peer-to-peer trust management system, targeted towards networks and applications supporting transactions or collaborations of a quantitative nature. MoR-Trust is based on the notion of expressing trust in terms of monetary units, thus directly coupling the trust estimates circulated in the network with the values of the transactions taking place and their outcomes. We have validated our design decisions and algorithms through simulation. The results indicate that our system converges towards a small error in the trust estimates distributed throughout the network.
