Trust management with delegation in grouped peer-to-peer communities

Trust Management is increasingly playing a major role especially with the growing need for security in decentralized, unsecured networks like peer-to-peer networks. Effective trust management solutions especially one geared towards handling trust in peer groups within peer communities are the key to handle the emerging security threats and scalability issues. Using a delegation infrastructure can provide a tremendous boost in terms of autonomy and division of labor in group based peer-to-peer communities.In our work we propose an effective trust system built on top of a peer group infrastructure that not only manages trust within communities but also between different communities. We also propose a delegation infrastructure that can be applied effectively to any grouped peer-to-peer community.
