Semantic access control in grid computing

Grid computing provides a computational infrastructure supporting flexible, secure, coordinated resource sharing among dynamic collections of individuals, institutions, and resources. Which means the grid should offer access for users and systems from various places. In order to protect the information and resource from abuse, access control in grid computing is therefore necessary and important. In this paper, a new approach is presented to authorize and administrate grid access requests, in which the requests are obliged to negotiate with a policy enforcement system in order to gain access to the target grid resources. This new method is called semantic access control as it exploits semantic Web technology, and use machine reasoning about the messages and policies at a semantic level.
