Open Challenges of Communication Security in an IoT Environment—A Survey

Abstract

Internet of Things (IoT) is a continuously growing concept in ICT concerning the progression of ubiquitous computing, machine-to-machine (M2M) communication, and wireless sensor networks. IoT is the network of physical objects such as watches and bicycles integrated with electronic equipment, sensors, and software. These devices gather and exchange data using network connectivity. However, with such an enormous number of IoT device connections on the network, the security of the data and communication become a major concern. This paper gives an overview of the IoT and the associated limitations and challenges of applying security in IoT devices and the classification of IoT attacks. Furthermore, the paper also discussed the security issues at different layers. Moreover, it demonstrates some identified solutions to the existing challenges and provides future direction to tackle the challenges present in IoT security.
