FairAccess: a new Blockchain‐based access control framework for the Internet of Things

Abstract Security and privacy are huge challenges in Internet of Things (IoT) environments, but unfortunately, the harmonization of the IoT‐related standards and protocols is hardly and slowly widespread. In this paper, we propose a new framework for access control in IoT based on the blockchain technology. Our first contribution consists in providing a reference model for our proposed framework within the Objectives, Models, Architecture and Mechanism specification in IoT. In addition, we introduce FairAccess as a fully decentralized pseudonymous and privacy preserving authorization management framework that enables users to own and control their data. To implement our model, we use and adapt the blockchain…
