“…θ t , θ r , and θ i represent the angle of refraction, the angle of reflection, and the angle of incidence. ϕ and ϕ + ∆ϕ denote the phase-discontinuity points of the two paths at the interface of the bimedium in the Equation (12). The variable ∆x denotes the distance between the intersecting points, and λ represents the wavelength of the electromagnetic wave in vacuum.…”

“…3 and 4, we can predict and design the reflection and refraction of electromagnetic waves on a metasurface by varying the parameter ∆ϕ ∆x [100]. Likewise, equation (12) shows that n i , n t , λ are constants. The value of θ t and θ r can be controlled to determine the direction of the reflected and refracted waves by adjusting ∆ϕ ∆x .…”

With the commercialization of the fifth generation mobile networks, researchers are now focusing on discovering the potential key techniques of the next generation mobile networks, which are expected to provide more accurate perception, lower latency, and higher network capacity. As the communication equipments increase exponentially, wireless transmission environment becomes more complex, leveraging wireless security challenges more and more severe, such as computationally powerful interception, intelligent malicious jamming, communication behavior monitoring. The physical layer security (PLS) techniques have been widely explored as a complement to traditional encryption schemes by exploiting the randomness characteristics of wireless channels to achieve the security from the physical layer. Additionally, reconfigurable intelligent surface (RIS) is considered as a key enabling technology for the six generation (6G) mobile networks, due to its ability to achieve the reconstruction of wireless channel, which is also regarded as a good match with PLS techniques for improving communication security. This paper presents a comprehensive review of the latest research on the integration of RIS and PLS. First, we introduce the principles of PLS from the development of secure communications and the basics of RIS based on the generalized Snell's law. Then, we categorize RIS according to different hardware architectures, of which the corresponding scenarios are also presented. Subsequently, we review recent works on RIS-assisted PLS in different communication networks, and classify the security scenarios in which RIS is integrated with various advanced communication technologies. Finally, we discuss the potential future research directions and challenges of RIS-aided PLS communications.INDEX TERMS Reconfigurable intelligent surfaces, physical layer security, secure communications, 6G.

“…1) Physical Layer Security Enhancement: Improving the security at the physical layer is a crucial aspect of wireless communication systems [193], [194]. The XL-MIMO technology offers substantial potential for enhancing physical layer security (PLS).…”

“…For example, the authors in [193] demonstrated that incorporating spherical-wavefront propagation in XL-MIMO configurations yields substantial PLS benefits. One of the advantages is the protection against eavesdroppers in similar angular orientations, which can otherwise threaten communication security under planar-wavefront propagation.…”

“…In addition, the authors in [195] investigated the effects of realistic propagation conditions on the achievable secrecy performance of MIMO systems in the presence of an eavesdropper (Eve), with a particular emphasis on the κ − µ shadowed fading model [196]. They derived closed-form expressions for secrecy performance metrics such as secrecy outage probability, probability of strictly positive secrecy capacity, and average secrecy capacity under two conditions: 1) the transmitter knew the CSI of the legitimate receiver (Bob) but not Eve's CSI, and 2) the transmitter knew the CSI of both the Bob's and Eve's channels [193]. The study also highlighted the effects of various propagation conditions and the number of antennas on the performance of secrecy.…”
