Security Model of Service Oriented Computational Grids

Grid infrastructure supports services on demand. Computational grids connected in a service oriented way thus forming virtual enterprises need several security measures to be undertaken. We have worked on several security measures like single sign-on through layered authentication model, dynamic token based authentication, privacy protection. In this paper, we try to simulate our observations using a testbed and find out the model for such measures. The approach is in the light of an interoperable model with solution to security issues particularly single sign-on, delegation of access rights, integration with various local authentication schemes, trust and privacy
