Abstract: Wireless networks offer great flexibility and ease of deployment for the rapid implementation of Internet of Things(IoT). However, these data network technologies are prone to security issues. Especially, the risk of eavesdropping attacks increases due to the inherent characteristics of the wireless medium. In this context, physical layer security (PLS) techniques can augment secrecy through appropriate coding and signal processing. These techniques are designed to enhance security against eavesdropping attacks. The main idea of PLS techniques is to exploit the random nature of the wireless channel to generate a secret key or to affect the signal-to-interference-noise ratio (SINR) of the eavesdropper. In other hand, the emergence of new wireless technologies like Internet of Things (IoT), massive machine-type communication (mMTC), 5G-Tactile Internet, vehicular communication for autonomous driving, remote surgery, instant control for sensitive IoT actuators, etc. makes current encryption-based methods unsuitable since these kind of technologies are naturally delay-sensitive, power-limited, and processing-restricted. All that problem could be mitigate with PLS techniques.
