Synopsis of Research Problem Wireless Physical Layer Security for Internet of Things (IoT) Applications

Wireless communication is one of the key technologies that actualize the Internet of Things (IoT) concept into the real world [1]. The foundation of the security management of IoT is laid by understanding the security performance of wireless communication. The term IoT is synonymous with the cyber–physical system, or a ‘‘network of networks’’ [2], where a variety of things (like sensors, mobile phones, gadgets, people) can interact with one another from any place in the world through an infrastructure like internet with unique addressing schemes, serves a crucial architecture for a wide range of promising applications such as e-health, intelligent transportation systems, and environmental monitoring [3,4]. As one of emerging technologies of IoT, wireless communication (e.g., wireless sensor network) plays an important role in collecting the data perceived by edge points (e.g., sensing nodes) from the surroundings so as to link the real time systems with the digital systems. Due to the open nature of the wireless medium, data collection through wireless communication may suffer from eavesdropping attacks by unauthorized things , posing a significant threat to the IoT security. Thus, extensive research efforts need to be devoted to the security performance study of wireless communications in the data collection process, which serves as a foundation for the security management of IoT.
