Security Framework for P2P Based Grid Systems

Grid and P2P systems enable users to share resources across organization boundaries. A strong security system is an integral component of grid middleware to enable secure resource sharing at a very large scale. P2P grid systems combine approaches from both worlds to share resources at a very large scale. P2P grid systems have a different set of security requirements contrary to the traditional server based centralized grid systems. This paper proposes a decentralized security framework for P2P grid systems. This framework is part of a P2P based data grid middleware DGET (data grid environment and tools)
