Many existing grid authorization systems adopt an inefficient structure of storing security policies for the available resources. That leads to huge repetitions in checking security rules. One of the efficient mechanisms that handle these repetitions is the Hierarchical Clustering Mechanism (HCM) [1]. HCM reduces the redundancy in checking security rules compared to the Brute Force Approach as well as the Primitive Clustering Mechanism (PCM). Further enhancement of HCM is done to make it suitable for dynamic environments [2]. However, HCM is not totally free from repetitions. Moreover, HCM is an expensive process in terms of decision tree size and memory consuming. In this paper, a new Rough Set based PCM is proposed which increases the efficiency of the authorization process and further reduces the redundancy.
