Design of Authorization-Pull Service for Community Authorization

Abstract:- This paper proposes an Authorization-Pull support for Community Authorization Services (CAS), an authorization-push model for the Grid authorization by the Globus Alliance, to evaluate it in the role of a pull model. The proposed system tries to evaluate the advantages and use of an authorization-pull model in the grid scenario making use of CAS and compares the same with the push-model originally proposed. The paper gives a design view of the proposed authorization system, and also discusses the security considerations and performance of the system proposed.
