SOGA: Fine-grained authorization for self-organizing grid

Abstract

The potential of truly large scale Grids can only be realized with Grid architectures and deployment strategies that lower the need for human administrative intervention, and therefore open the Grid to wider participation from resources and users. Self-Organizing Grids (SOGs) was proposed to address this issue. Current general solutions for Grid authorization are not scalable enough, inflexible, inefficient, coarse-grained, or require too much administrative work, thus do not fit for the needs of SOGs. The arising Semantic Web can contribute to a solution. In this paper, we propose SOGA, a fine-grained authorization architecture for SOG environment. Its characteristics includes, policy based authorization, fine-grained access control, dynamic environment monitor and ontology driven access rights reasoning. © Springer-Verlag Berlin Heidelberg 2007.
