This book discusses the problems of Physical Layer Security (PLS) in Intelligent Reflecting Surface (IRS)-assisted wireless networks. It also discusses the corresponding methods to solve these problems in a comprehensive style. Furthermore, some potential challenges are well analyzed. This book is divided into 11 chapters. Chapter 1 introduces the propagation characteristics of IRS-aided PLS communications. From Chapter 2 to Chapter 10, The authors mainly provide deep investigations of different PLS problems of IRS-aided wireless networks, namely, directional modulation (DM) networks. Chapter 11 draws a conclusion and includes the future research directions. Researchers working in wireless communications, or advanced-level computer science or electrical engineering students, can learn about secure communication in the physical layer through our book. Professionals or engineers working in this field will also benefit from this book.

The primary principle of designing a wireless communication system is to ensure the security of wireless data transmission. The conventional cryptography technology is so heavily dependent on the complex encryption and decryption protocols and key management mechanisms that it cannot friendly support the large-scale devices. Different from cryptography schemes, the physical-layer secure (PLS) technology including channel coding and precoding takes full advantage of the physical characteristics (i.e. noise, fading, interference) of wireless channel to obtain a secure and efficient data transmission. The traditional error correction coding can be modified by the channel coding technology to have the abilities to correct error and keep security, and the quality of eavesdropping channels can be poor by precoding technology to improve the security rate of the wireless communication system, so that a lightweight secure transmission scheme can be provided by the above two PLS technologies for the resource-constrained devices.

Recently, intelligent reflecting surface (IRS) has become a hot topic of research. By adjusting the reflection amplitude and phase of each IRS element, friendly multipaths can be created to achieve energy consumption reduction, signal enhancement and coverage extension. In view of these advantages, IRS has been applied to the PLS communication in some recent research. The IRS-aided PLS communication can be viewed as a new research direction, which has drawn much attention from research community.
As far as we know, there is no book focusing on the IRS-aided PLS communication networks. This book presents concepts and technologies, which are related to the topic of IRS-aided PLS communication in different application scenarios. Additionally, some insightful discussions and effective recommendations are available in this book.
