A semantic access control model for grid services
Junzhou Luo, Xiaopeng Wang, Aibo Song · 2005
Grid computing is appropriate for supporting cooperative work Many designers and engineers from different companies or institutions can dynamically form a virtual organization for a given design task. In order to protect each company's sensitive data and services, access control is therefore necessary and important. In this paper, we present a new approach to authorize and administrate access requests, in which the requests are obliged to negotiate with a policy enforcement point in order to gain access to the target grid service. The new access control model will exploit semantic Web technology, and use machine reasoning about the messages and policies at a semantic level.
