Concurrent HCM for authorizing grid resources

Abstract

Grid computing is concerned with a shared and coordinated use of heterogeneous resources, belongs to distributed virtual organizations to deliver nontrivial quality of services. In grids, security has a major concern. The heterogeneity, massiveness and dynamism of grid environments complicate and delay the authorization process. This brings out the need for a fast and scalable fine-grained access control (FGAC) mechanism to cater well to grid requirements. © 2012 Springer-Verlag.
