An Object Oriented Role-based Access Control Model for Secure Domain Environments

Abstract

In the secure domain computing environments, it is important to keep resources and information integrity from unauthorized access. Therefore, there is a strong demand on the access control for shared resources. In the past few years, Role-based Access Control (RBAC) has been introduced and offered a powerful means of specifying access control decisions. In this paper, an Object Oriented RBAC model (ORBAC) that efficiently represents the real world is proposed. It not only supports a single secure domain authorization for an enterprise, but also supports multiple secure domains access control for E-business carried out by multiple enterprises over the Internet.
