Integrating an efficient authorization protocol with trigon-based authentication mechanism for improving grid security

Abstract

Security is a vital part of an integrated grid application in which heterogeneous services and resources belonging to multiple domains are distributed dynamically. Authentication and authorization are the major security concerns in grid environment. Most of the grid security mechanisms stress on authentication, and not on authorization. This paper proposes to integrate an authorization protocol with the effective trigon-based authentication technique based on the user's role. This integrated trigon-based authentication - authorization protocol provides effective grid security in an efficient manner. © 2010 Springer-Verlag Berlin Heidelberg.
