Device authentication schemes in IoT: A Review

Abstract

Internet of Things (IoT) is one of the most promising technologies and has wide spread application areas in the information technology for future products and services. Developments in IoT have given rise to device proliferation which in turn increase IoT challenges such as security. One of the security challenges is the authentication of heterogeneous devices in the network. Due to the unique nature of these devices, traditional security schemes proposed and developed over the years have been rendered inept and infeasible for IoT application. However, several lightweight solutions have also been proposed for IoT application, but are far from being efficient. Therefore, this paper performed a review on some of these studies in order to comprehend the challenge, identify some of the approaches offered, and provide recommendations for future research. We reviewed about 9 articles and our analysis shows authentication is still an open issue in IoT and there is no generic approach to authenticate devices.
