Five Layer Security Architecture & Policies for Grid Computing System
In this paper, the authors described four layer architecture of Grid Computing System, analyzes security requirements and problems existing in Grid Computing System. This paper presents a new approach of five layer security architecture of Grid Computing System, defines a new set of security policies & gives the representation. State of the art and emerging scientific applications requires high performance computing. It is not possible to solve large quantities of data and problems using a single high performance computer or a single computer cluster.
