Authentication in Internet of Things: State of Art

Abstract

Internet of Things (IoT) is a system of wireless electronics that may visualize and control much of the world that surrounds us. This new concept brings with it a broad range of research challenges. Rather, the highly critical challenge of IoT networks is security and particularly authentication. This paper consists of an exhaustive study about authentication in the IoT environment. Accordingly, we present analysis result of a comparison study between eleven IoT authentication schemes. The main criteria of our comparison are cryptography techniques, security services provided, resistance against attacks and computational cost. At the end, this paper will highlight the weaknesses of current IoT authentication and propose future research directions.
