“…In the context of smart radio, IRS offers a fresh approach for boosting network secrecy in vehicles. IRS can enhance the desired signals or suppress unwanted signals by adaptively altering the phase shift of the reflecting elements [11,15]. This is done by manipulating the reflected signal's addition to the non-IRS reflected signal at the receiver in a positive or negative manner.…”

It is anticipated that sixth-generation (6G) systems would present new security challenges while offering improved features and new directions for security in vehicular communication, which may result in the emergence of a new breed of adaptive and context-aware security protocol. Physical layer security solutions can compete for low-complexity, lowdelay, low-footprint, adaptable, extensible, and context-aware security schemes by leveraging the physical layer and introducing security controls. A novel physical layer security scheme that employs the concept of radio frequency fingerprinting (RF-FP) for location estimation is proposed, wherein the RF-FP values are collected at different points with in the cell. Then, based on the estimated location, the nearest possible road-side unit for sending the information signal is located. After this, the effects on secrecy capacity (SC) and secrecy outage probability (SOP) in the presence of multiple eavesdropper per unit time are analysed. It has been shown via simulations that the proposed RF-FP scheme increases SC by up to 25% for the same signal-to-noise ratio (SNR) values as those of the benchmarks, while the SOP tends to decrease by up to 30% as compared to the benchmark scheme for the same SNR value. Thus, the proposed RF-FP-based location estimation provides much better results as compared to the existing physical layer security schemes. K E Y W O R D S radio links, security of data | INTRODUCTION 1.| MotivationThe rapid advancements in wireless communication and the rapid expansion in urbanisation have paved the way for new frontiers in the domain of cellular communication. Sixth Generation (6G) technology is considered to be a new candidate in this line of advancement. 6G has promised to overcome the shortcomings of Fifth Generation (5G) and Beyond 5G (B5G) by exploiting the terahertz (THz) range. One of the features provided by 6G is to reduce latency, that is, reduce the delay in time by 1/100 of a millisecond. 6G is estimated to provide the highest data rates, that is, 1 Tbps, along with much better support for machine to machine communication, energy efficiency, network reliability, and the use of artificial intelligence (AI) and machine learning (ML) for optimal connectivity [1, 2].

“…In addition, the use of RIS in cooperative networks can provide higher SR, SC, and secure energy efficiency (SEE). Thus, RIS is regarded as an effective way to support the wireless security of various networks, such as unmanned aerial vehicle (UAV) relay networks [38], [51]- [58], satellite communication networks [59]- [61], NOMA networks [48], [55], [62]- [74], cognitive radio networks [48], [57], [75], and cell-free networks [76], [77], which will be discussed in the main text.…”

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.
