Abstract
In order to collaborate large numbers of heterogeneous distributed devices over multiple domains within a modern large-scale device collaboration system, a fine-grained, flexible and secure approach is required for device authentication and authorization. This paper proposed a Multiple-Policy supported Attribute-Based Access Control model and its architecture to address these demands. With eXtensible Access Control Markup Language standard, this model exceeds the traditional Attribute-Based Access Control Model by providing cross-domain authentication and authorization, hierarchical policy combination and enforcement, unified device access control and fine-grained attributes-based privilege description. Experiments show the performance of this architecture is acceptable within production environment.
