“…Alternating optimization (AO) and successive convex In vehicular ad hoc networks (VANET), PLS is a major concern, due to the broadcast nature of the wireless channels. Many papers, [26]- [28], have considered the analysis of PLS under such high mobility conditions and dynamic environments. In fact, RIS is proven to help compensating the multipath and Doppler effects in wireless propagation channels [6].…”

With the emergence of the internet of things (IoT) technology, wireless connectivity should be more ubiquitous than ever. In fact, the availability of wireless connection everywhere comes with security threats that, unfortunately, cannot be handled by conventional cryptographic solutions alone, especially in heterogeneous and decentralized future wireless networks. In general, physical layer security (PLS) helps in bridging this gap by taking advantage of the fading propagation channel. Moreover, the adoption of reconfigurable intelligent surfaces (RIS) in wireless networks makes the PLS techniques more efficient by involving the channel into the design loop. In this paper, we conduct a comprehensive literature review on the RIS-assisted PLS for future wireless communications. We start by introducing the basic concepts of RISs and their different applications in wireless communication networks and the most common PLS performance metrics. Then, we focus on the review and classification of RIS-assisted PLS applications, exhibiting multiple scenarios, system models, objectives, and methodologies. In fact, most of the works in this field formulate an optimization problem to maximize the secrecy rate (SR) or secrecy capacity (SC) at a legitimate user by jointly optimizing the beamformer at the transmitter and the RIS's coefficients, while the differences are in the adopted methodology to optimally/sub-optimally approach the solution. We finalize this survey by presenting some insightful recommendations and suggesting open problems for future research extensions.

“…However, the aforementioned works were for static users, therefore, to tackle the security and privacy issue in vehicular networks, the work in [11] double Rayleigh fading has been considered and the authors have provided the expression to model the fading with mobility. On the other hand, by considering the interfere scenario, the work in [12], has highlighted the performance of secrecy capacity and the closed form expressions have been derived using moment generating function. However the work in [13]- [15] shows that for cognitive vehicular networks, where the network topology is highly dynamic, PLS is a promising approach because of its no requirement of exchange of keys.…”

Physical layer security (PLS) is an essential way to provide security to users in wireless networks against active or passive attacks. The quantification of the provided security is measured through secrecy outage probability and outage probability. For cognitive vehicular networks (CVN), PLS can increase the amount of the quality of services in infotainment applications. Due to the broadcast nature of the wireless channels, it is challenging to achieve the perfect secrecy between the transmitting and receiving nodes. Furthermore, in CVN, when resources are being shared in an underlay manner, the need arises to find the highest and lowest achievable quantification of performance measures for poor fading scenarios. The knowledge of the maximum achievable performance helps to design and develop the anti eavesdropping solutions. In a particular direction, firstly, this paper finds the closed-form expressions of first-order secrecy metrics over multiple input multiple output 2x2 Nakagami-m channel for vehicular networks. The derived closed-form expressions are further utilized to find the upper and lower bounds of secrecy outage probability, and outage probability using the integral bound method for CVN. The derived bound provides the knowledge of the region over a valid signal-to-noise ratio for which the maximum and minimum achievable performance can exist. To restrict the amount of eavesdropping, the convex optimization-based approach is proposed. The optimization method helps secrecy metrics to remain in a specific region of the value. Therefore, the work provides insights over the classical approach and the information-theoretic approach. These works enhance the knowledge to prepare the anti-eavesdropping methods for connected cars. Moreover, the derived analytical expressions demonstrate the impact of the wireless medium on secrecy performance while the derived bound demonstrates the impact of the magnitude of wireless fading parameters.

“…The true flooding method is used to recognize intruder nodes depending on the evaluation of trust value. Makarfi et al [22] presented the ordinary logarithmic expression for the system capability in a different form, to allow the study of the random variables describing the channel fading and interference in terms of the joint moment generating functions (MGF). In [23], an interference management method for PLS in a two-tier HetNet system to increase the user's secrecy rate under eavesdropping attack is proposed.…”

One of the major applications of the Heterogeneous Network (HetNet) is in the healthcare system. Deploying HetNet in healthcare systems enables patients, physicians, and other stakeholders to communicate easily with each other. Due to the large growth in the network's subscribers, the security of the stored health data became one of the major concerns because unauthorized access to this data may lead to very serious complications, and unreliable transmission of data may lead to fatal risks to the patient's life. Therefore, taking data integrity into consideration, user authentication has become one of the main factors. However, significant research work has been performed at HetNet's physical layer to secure communication, but the result of this leads to an increase in hardware components. The increasing hardware components not only costs money but also power consumption. Therefore, this paper presents an alternate way of securing communication in HetNet at the network layer. However, resolving security problems at the network layer increases computational complexity. Nevertheless, earlier, some encryption techniques like identity-based encryption (IBE), symmetric key encryption (SKE), and public-key encryption (PKE) have been utilized for securing data. Due to their own disadvantages, this paper utilizes an attribute-based encryption (ABE) authentication scheme for securing health data in medical applications. With the help of this method, access to the intruders is denied which results in reduced communication overhead. This authentication scheme helps protect the essential information against attacks by the intruders. It includes a third party server that helps to authenticate and store patient's information. The whole security technique has been written in the form of HLPSL (high-level protocol specification language) codes, and the results are then validated with the help of AVISPA (automated validation of Internet security protocols and applications) tool.
