A Flexible and Centralized Approach for Access Control in Heterogeneous IoT Environment

Abstract

In this article, the researchers introduce a 3-level model for security access control that comes as an extension to ABAC. This extension augments its structural and hierarchical expressiveness allowing to define arbitrarily complex access control rules. The authors apply this model to IoT platforms and show how it fulfils security access control requirements of these platforms. Finally, a reference architecture is introduced for access control applied to connected objects and its implementation details are presented.
