| Abstract | There is no doubt that Internet of Things (loT) occupy a very important role in our daily lives. Indeed, numerous objects that we use every time, are being equipped with electronic devices and protocol suites in order to make them interconnected and connected to the Internet. In loT, things process and exchange data without human intervention. Therefore, because of this full autonomy, these entities need to recognize and authenticate each other as well as to ensure the integrity of their exchanged data. Otherwise, they will be the target of malicious users and malicious use. Due to the size and other features of IoT, it is almost impossible to create an efficient centralized authentication system. To remedy this limit, in this paper, we propose an original decentralized system called bubbles of trust, which ensures a robust identification and authentication of devices. Furthermore, it protects the data integrity and availability. To achieve such a goal, our approach relies on the security advantages provided by blockchains, and serves to create secure virtual zones (bubbles) where things can identify and trust each other. We also provided a real implementation of our mechanism using the C++ language and Ethereum blockchain. The obtained results prove its ability to satisfy loT security requirements, its efficiency, and its low cost. (C) 2018 Elsevier Ltd. All rights reserved. |
