Physical layer security is a promising approach that can benefit traditional encryption
methods. The idea of physical layer security is to take advantage of the propagation …

Reconfigurable Intelligent Surface (RIS) can create favorable multipath to establish strong
links that are useful in millimeter wave (mmWave) communications. While previous works …

TeraHertz (THz) communications can satisfy the high data rate demand with massive
bandwidth. However, severe path attenuation and hardware imperfection greatly alleviate its …

5G networks must provide a highly resilient, secure, and privacy-protected platform to
support the emergence of new business and technologies expected from the so-called …

The statistical characterization of a sum of random variables (RVs) is useful for investigating
the performance of wireless communication systems. We derive exact closed-form …

This paper investigates the impact of realistic propagation conditions on the achievable
secrecy performance of multiple-input multiple-output systems in the presence of an …

Spoofing Attack (SA) is a challenging issue in mobile wireless communication especially
with huge traffic in 5G and beyond where attacker inserts counterfeit data with false …

Novel methods to approximate the probability density function of the product, ratio, and sum
of α‐μ random variables are presented in this article. The approximations are simple to …

The authors analyse the effect of correlation between the forward and backward links on the
capacity of backscatter communication systems. With that aim, we obtain an analytical …

This chapter presents the fundamentals of physical layer security (PLS) and its road‐map
toward 6G. After reading this chapter you should be able to: Understand the main concepts …
