“…Also note that, for lower values of δ, the impact of LoS available on the RF links, especially on B, is more significant, as expected given that, in those conditions, the RF link is the main source of leakage to E. Moreover, it can be observed that, it is better to allocate more rate for the VLC link in terms of secrecy. On the other hand, with both B and E located at the edge of the VLC coverage, better performance is obtained as more data rate is allocated to the RF link, since according to (6), the secrecy capacity of the VLC link is based on the position of the nodes and it is only positive if B is closer to the source than E. In this case, the performance is slightly improved when E has a smaller LoS component. Fig.…”

“…Moreover, with the introduction of disruptive technologies and novel services, 6G networks must assure a high level of security and privacy, so that traditional cryptography-based techniques might not be suitable or enough for some applications, especially those of constrained scenarios, e.g. limited hardware and restricted computing power [6] . Hence, physical layer security (PLS) techniques might found a new horizon on 6G to provide security by efficiently exploiting the randomness of wireless channels.In this regard, there exists special interest in investigating PLS techniques on VLC networks under secrecy constraints [7], [8].…”

This paper evaluates the secrecy outage probability of a hybrid radio frequency (RF) and visible light communication (VLC) network in the presence of an eavesdropper. We assume that data is transmitted over the RF and VLC links following a proposed multiplexing scheme in which the data sent by the source is split with a certain allocation ratio. Furthermore, the legitimate and eavesdropper users are assumed to have multihoming capabilities, so that they are able to receive data from both RF and VLC access points, simultaneously. We derive integral-form exact expression, as well as a closedform asymptotic expression for the secrecy outage probability and validate them via Monte Carlo simulations. Our results show that multiplexing the information signal by both links leads to an enhancement of the secrecy performance since it opportunistically takes advantages of the best characteristics of both domains.

“…To circumvent this problem, physical layer authentication (PLA) emerge as a viable solution to provide secure communications with low latency and light signalling overhead, compatible with IoV applications, by relying on the unique channel properties or inherent attributes of communication devices to perform the authentication of vehicles [86], [87]. Based on this, [88] proposed a V2X PLA scheme that uses a Kalman filter to refine the iterative model and threshold model in the authentication mode.…”

The conceptualisation of the sixth generation of mobile wireless networks (6G) has already started with some potential disruptive technologies resonating as enablers for driving the emergence of a number of innovative applications. Particularly, 6G will be a prominent supporter for the evolution towards a truly Intelligent Transportation System and the realisation of the Smart City concept by fulfilling the limitations of 5G, once vehicular networks are becoming highly dynamic and complex with stringent requirements on ultra-low latency, high reliability, and massive connections. More importantly, providing security and privacy to such critical systems should be a top priority as vulnerabilities can be catastrophic, thus there are huge concerns regarding data collected from sensors, people and their habits. In this paper, we provide a timely deliberation of the role that promissory 6G enabling technologies such as artificial intelligence, network softwarisation, network slicing, blockchain, edge computing, intelligent reflecting surfaces, backscatter communications, terahertz links, visible light communications, physical layer authentication, and cell-free massive multiple-input multiple-output (MIMO) will play on providing the expected level of security and privacy for the Internet of Vehicles.

“…Disruptive technologies, such as SDN and NFV, allow the deployment of customized security configurations, thus enabling the deployment of security-as-a-service [77]. By exploiting the physical properties and randomness of wireless channels, physicallayer security techniques are considered promising solutions to complement upper layer schemes and provide compatible solutions with the requirements of MTC networks [78]. Thus, those techniques may find a place in the definition of 6G security solutions.…”

The recently introduced 5G New Radio is the first wireless standard natively designed to support critical and massive machine type communications (MTC). However, it is already becoming evident that some of the more demanding requirements for MTC cannot be fully supported by 5G networks. Alongside, emerging use cases and applications towards 2030 will give rise to new and more stringent requirements on wireless connectivity in general and MTC in particular. Next generation wireless networks, namely 6G, should therefore be an agile and efficient convergent network designed to meet the diverse and challenging requirements anticipated by 2030. This paper explores the main drivers and requirements of MTC towards 6G, and discusses a wide variety of enabling technologies. More specifically, we first explore the emerging key performance indicators for MTC in 6G. Thereafter, we present a vision for an MTC-optimized holistic end-to-end network architecture. Finally, key enablers towards (1) ultra-low power MTC, (2) massively scalable global connectivity, (3) critical and dependable MTC, and (4) security and privacy preserving schemes for MTC are detailed. Our main objective is to present a set of research directions considering different aspects for an MTC-optimized 6G network in the 2030-era.
