Abstract

The proliferation of smart gadgets, appliances, mobile devices and sensors has enabled the construction of pervasive computing environment, transforming regular physical spaces into "Active Information Spaces". However, access control remains a major challenge for the deployment of this computing paradigm in real-life. A context access control model based on UCON_ABC model is presented in this paper, which not only focuses on authorization, but also introduces obligations, and conditions. And it includes pre-authentication, pre-condition, pre-obligation, active-right and passive-right sub-models. The operations of sub-models are presented. And the security, flexibility and usefulness of our proposed model are demonstrated by a typical pervasive computing scenario.
