Secrecy, Covertness and Authentication in Wireless Communications: Physical Layer Security Approach

This book introduces the fundamentals of physical layer security (PLS) and demonstrates how a variety of PLS techniques can be applied to improve the security of wireless communication systems. In particular, this book covers three security aspects of wireless communications. It includes secrecy, i.e., preventing eavesdroppers from intercepting information from transmitted wireless signals, covertness, i.e., hiding the transmitted signals themselves from malicious wardens and authentication, i.e., authenticating the identities of communicating entities.

When discussing the secrecy of wireless communication systems, this book covers physical layer secure communication in multiple-input multiple-out (MIMO) systems based on beamforming and precoding techniques, in relay systems based on link/relay selection and in large-scale random networks based on cooperative jamming. Regarding the covertness of wireless communication systems, this book introduces physical layer covert communication in relaying systems and MIMO systems. Also, when discussing authentication in wireless communication systems, this book introduces the implementation of physical layer authentication in MIMO systems based on channel features and/or radiometric features of transceivers. In addition, this book presents security-aware routing in wireless networks based on physical layer secure communication techniques.

This book targets researchers in the fields of physical layer security and wireless communications security. Advanced-level students in electronic engineering or computer science studying these security topics will also want to purchase this book as a secondary textbook.

本書介紹了物理層安全（PLS）的基礎知識，並展示了如何應用各種PLS技術來提高無線通信系統的安全性。具體而言，本書涵蓋了無線通信的三個安全方面。其中包括保密性，即防止竊聽者從傳輸的無線信號中截取信息；隱蔽性，即將傳輸的信號本身隱藏起來，使惡意監視者無法察覺；以及身份驗證，即驗證通信實體的身份。

在討論無線通信系統的保密性時，本書介紹了基於波束成形和預編碼技術的多輸入多輸出（MIMO）系統中的物理層安全通信，基於鏈路/中繼選擇的中繼系統中的物理層安全通信，以及基於合作干擾的大規模隨機網絡中的物理層安全通信。關於無線通信系統的隱蔽性，本書介紹了中繼系統和MIMO系統中的物理層隱蔽通信。此外，在討論無線通信系統的身份驗證時，本書介紹了基於通道特徵和/或收發器的輻射特徵的MIMO系統中的物理層身份驗證的實現。此外，本書還介紹了基於物理層安全通信技術的無線網絡中的安全感知路由。

本書的目標讀者是物理層安全和無線通信安全領域的研究人員。對於電子工程或計算機科學專業的高級學生來說，如果他們正在學習這些安全主題，也會希望將本書作為輔助教材購買。
