Abstract

The heterogeneous and dynamic nature of a grid environment demands a scalable authorization system. This brings out the need for a fast fine-grained access control mechanism for authorizing grid resources. Existing grid authorization systems adopt inefficient mechanisms for storing resources' security policies. This leads to a large number of repetitions in checking security rules. One of the efficient mechanisms that handle these repetitions is the Hierarchical Clustering Mechanism (HCM). HCM reduces the redundancy in checking security rules compared to the Brute Force Approach (BFA) as well as the Primitive Clustering Mechanism (PCM). Further enhancement is done to HCM to increase the scal..
