Data-Centric Security for the IoT.

This work presents a paradigm shift and introduces a datacentric security architecture for the COMPOSE framework; a platform as a service and marketplace for the IoT. We distinguish our approach from classical device- centric approaches and outline architectural as well as infrastructural specifics of our platform. In particular, we describe how fine- granular and data- centric security requirements can be combined with static and dynamic enforcement to regain governance on devices and data without sacrificing the intrinsic openness of IoT platforms. We also highlight the power of our architecture, converting concepts such as data provenance and reputation into efficient, highly useful, and practically applicable complements.
