Physical-Layer Security and Quantum Key Distribution

This textbook integrates the most advanced topics of physical-layer security, cryptography, covert/stealth communications, quantum key distribution (QKD), and cyber security to tackle complex security issues. After introducing the reader to various concepts and practices, the author addresses how these can work together to target problems, rather than treating them as separate disciplines. This book offers students an in-depth exposition on: cryptography, information-theoretic approach to cryptography, physical-layer security, covert/stealth/low-probability of detection communications, quantum information theory, QKD, and cyber security; to mention few. The goal is to provide a unified description of the most advanced topics related to: (i) modern cryptography, (ii) physical-layer security, (iii) QKD, (iv) covert communications, and (v) cyber security. Each chapter is  followed by a set of problems. Also, for readers to better understand the book, an appendix covers all needed background. Homework problems and lecture notes are available online. The book does not require any prior knowledge or prerequisite material.         Integrates modern cryptography, physical-layer security, QKD, covert communication, and cyber security technologies and shows students how they can work together to solve issues        Does not require prior knowledge in corresponding fields or prerequisite material except basic concepts on vector algebra at undergraduate level.         Can be used in multiple courses, such as modern cryptography, physical-layer security, QKD, or a combination of these.
