Security and Privacy in Wireless IoT

Abstract

The 13 articles in this special section focus on security and privacy in wireless Internet of Things (IoT). IoT is a paradigm that involves networked physical objects with embedded technologies to collect, communicate, sense, and interact with the external environment through wireless or wired connections. With rapid advancements in IoT technology, the number of IoT devices is expected to surpass 50 billion by 2020, which has also drawn the attention of attackers who seek to exploit the merits of this new technology for their own benefits. There are many potential security and privacy threats to IoT, such as attacks against IoT systems and unauthorized access to private information of end users. As IoT starts to penetrate virtually all sectors of society, such as retail, transportation, healthcare, energy supply, and smart cities, security breaches may be catastrophic to the actual users and the physical world. To tackle the security challenges in the design of future wireless IoT systems, we have organized this Special Issue focusing on the security, privacy, and performance of future wireless IoT.
