The OGSA definition of a Grid Service as a transient, stateful and dynamically instantiated Web Service introduced new authentication and authorization requirements beyond those already established for existing Grid environments. However such design features have begun to be developed currently following a pre-Web Services approach in two aspects: in the first place making a clear separation of authentication from authorization issues, and in the second place not designing them over the OGSI/WSRF defined mechanisms and specifications. In this paper we are proposing a new Security Framework that unifies identified common points of both features, Authentication and Authorization, into a mechanism called validation policy which is expected to improve service performance and security. Our framework seeks to implement these aspects over the Grid Service’s Operations and Service Data concepts to fully exploit its functionalities. The paper also presents the integration of an enhanced OCSP Service Provider into the Globus Toolkit 3.9.4 as a first proof of concept.
