"Physical layer security has recently become an emerging technique to complement and significantly improve the communication security of wireless networks. Comparing to the cryptographic approaches, physical layer security is a fundamentally different paradigm, where secrecy is achieved by exploiting the physical layer properties of the communication system, such as thermal noise, interference, and the time-varying nature of fading channels. Written by pioneering researchers, this book provides a systematic overview of the foundations and recent developments of this promising security technology"-- Provided by publisher.
