Grid is a collection of distributed computing resources. These resources are available over a local or wide area network that appears to an end user or application as one large virtual computing system. The vision is to create virtual dynamic organizations through secure and coordinated resource-sharing among individuals and institutions. Access control to these resources is a problem difficult to manage, how to store and manage the security policies of such a system plays a key role. If these policies are not properly stored, the response time to access control requests will be dramatically increased. Grid Authorization Graph (GAG) was proposed to improve the authorization efficiency by eliminating the redundancy in checking security rules. This article proposes the Weighted Grid Authorization Graph (WGAG) as an enhancement to GAG which further improves the authorization efficiency by avoiding a lots of security rule checking. Finally, as proof of concept, we implement the WGAG simulator where simulations were done. The obtained results show that the proposed model can effectively reduce the complexity of security rule checking and gave better results than GAG.
