A Survey on Internet of Things (IoT): Communication Model, Open Challenges, Security and Privacy Issues

Abstract

In recent years, the Internet of things is an emerging research topic, where the Internet devices like computers, everyday objects, sensors, and actuators are being linked through wired and wireless networks in the world and its computing capabilities allowing the data exchanges and consumption with very minimal human interaction. The IoT incorporates many multifarious end devices to provide open access to digital data services over the Internet. In the meantime, security and privacy are two inseparable areas of this technology. It has been observed that there are several potential risks that exist in ensuring confidentiality, authentication, and integrity among the IoT applications. In this paper, the authors begin with the brief introduction of IoT protocol stack along with the security models supported by each layer. Later, this survey analysis the security and privacy risk of the IoT model and its open challenges. Finally, the authors discussed the approaches and a few recommendations to ensure the fundamental securities of IoT applications.
