Dynamic and fine-grained authentication and authorisation for grid computing
The Globus Toolkit makes it very easy and comfortable for grid users to develop and deploy grid service. As for its security mechanism, however, only static authentication and coarse-grained authorisation are provided in the current Globus Toolkit. In this paper we address the limitations of the current security mechanism in the Globus Toolkit and propose a new architecture, which provides a fine-grained and flexible security mechanism. To implement this without modifying existing components, we make use of the Aspect-Oriented Programming technique.
