The advent of wireless communication has revolutionized the way we connect and share information. However, with this convenience comes the challenge of ensuring the security of data transmitted over the airwaves. This book delves into the critical domain of Physical Layer Security (PLS), focusing on key generation and authentication technologies that leverage the unique characteristics of wireless channels to safeguard communication against eavesdropping and other malicious attacks. Part I of the book is dedicated to the exploration of key generation technology based on channel characteristics. Part II shifts the focus to physical layer security technology based on channel characterization.
