The Security Architecture for Open Grid Services

Abstract

This document proposes a strategy for addressing security within the Open Grid Services Architecture (OGSA). It defines a comprehensive Grid security architecture that supports, integrates and unifies popular security models, mechanisms, protocols, platforms and technologies in a way that enables a variety of systems to interoperate securely. This security architecture is intended to be consistent with the security model that is currently being defined for the Web services framework used to realize OGSA’s service-oriented architecture. The document presents a security model, describes a set of security components that need to be realized in the OGSA security architecture, and presents a set of use patterns that show how these components can be used together in a secure Grid environment.
