DRM Application in UCONABC

Abstract

In this paper, we introduce the elementary UCONABC models for usage control (UCON), which integrate Authorizations (A), oBligations (B), and Conditions (C). We call these core models because they address the essence of UCON. UCONABC covers traditional access controls such as mandatory, discretionary, role-based access control, digital rights management (DRM) and other modern access controls. In the later part of the paper, the example of DRM application in UCONABC model is given to support the feasibility of UCONABC in real computer and information security world.
