VLC Physical Layer Security through RIS-aided Jamming Receiver for 6G Wireless Networks

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].

The development of sixth‐generation (6G) wireless communication technology is expected to provide super high‐speed data transmission, and advanced network performance than the current fifth‐generation (5G) and be fully functional by the 2030s. This development will have a significant impact and add improvements to digital extended reality (XR), autonomous systems, vehicular ad hoc networks (VANETs), artificial intelligence (AI), underwater communications, blockchain technology, pervasive biomedical informatics and smart cities built on the digital infrastructure backbone of the Internet of Things (IoT). The ubiquitous nature of this large‐scale 6G‐enabled IoT that offers faster connectivity capabilities and integrates both terrestrial and non‐terrestrial networks will not only create new data security and privacy issues but also provide a treasure trove of digital evidence useful for digital forensic examiners investigating security incidents and cybercrime. However, for digital forensic examiners, evidence collection, preservation and analysis will become a priority in the successful deployment of 6G IoT networks. In this study, we define key applications of 6G network technology to the Internet of Things and its existing architectures. The survey introduces potential digital forensic challenges and related issues affecting digital forensic investigations specific to 6G IoT networks. Finally, we highlight and discuss forensic readiness and future research directions for identified challenges within the 6G IoT network environments.This article is categorized under: Digital and Multimedia Science > IoT Forensics

“…In RIS-aided VLC systems, phase control is not directly applicable, as these systems operate with intensity modulation and direct detection (IM/DD), focusing solely on the non-negative and real part of the signal [107]. There are three primary approaches to incorporating RIS into VLC systems, namely, mirror array-based RIS [107]- [111], metasurface-based RIS [112]- [116], and liquid crystal (LC)-based RIS [117]- [120]. Both the mirror array-based and metasurface-based optical RISs consist of nearly-passive elements in the form of mirror arrays or intelligent metasurfaces used to control incident lights based on the light reflection or refraction principle and the manipulation of the EM waves, while the latter uses LCs as front-row materials embedded in a layered structure to control light reflection and/or refraction.…”

Relay Selection for Improving Physical Layer Security in D2D Underlay Communications

This paper investigates the physical layer security of inband underlay Device-to-Device (D2D) communication, where the direct link between D2D users is not available. In this respect, optimal relay and suboptimal relay selections are utilized to secure the D2D transmission. The eavesdropper uses either maximal-ratio combining or selection combining to increase the wiretapped signals. The D2D secrecy performance analysis is performed regarding the secrecy outage probability (SOP) and the probability of non-zero secrecy capacity, and closed-form expressions are provided for both relay selection approaches and verified using Monte-Carlo simulation. From the numerical results, it is shown that increasing the number of D2D relays enhances the secrecy performance of D2D communications. Moreover, the exact asymptotic analysis of the SOP is provided. It turns out that the diversity order of both relay selection approaches is the same.INDEX TERMS Physical layer security, D2D communications, secrecy outage probability, optimal and suboptimal relay selection, maximal-ratio combining, and selection combining., 1
