A scalable authorization approach for the Globus grid system

Grid computing has received widespread attention in recent years as a significant new research field. To date, there has been only limited work on the problem of grid system authorization. In this paper, we address the authorization problem in grid system environments and propose a solution for authorization within Globus system. Our authorization approach is based on distributed authorization servers and extensions to Globus' Metacomputing Directory Service (MDS). The goal is to provide a scalable authorization approach that is able to meet the requirements of a dynamic grid environment.
