Abstract
With the widespread usage of Internet-enabled devices, the Internet of things (IoT) has become popular and well integrated in different countries nowadays. However, the huge amount of data generated from several smart devices in the same IoT network, security of the network and the limited devices capacities of storage and process are a very big concern. To treat such a large database generated from all devices in the IoT network and to handle their security issues, Software Defined Network (SDN) has emerged as a key approach. Keeping focus on security challenges, several entities must authenticate each other before any communication to ensure a trusted network. We adopt in this paper the SDN architecture for an IoT environment, including authentication schemes for things and users based on Elliptic Curve cryptography (ECC).
