“…Artificial noise based beamforming was adopted in [71]- [75]. Specifically, in [71], [72], the proposed schemes consist of transmitting the information bearing signal from one AP and jamming signals from the remaining APs. Moreover, the information bearing and jamming signals were assumed to follow uniform distributions in [71] and truncated Gaussian distributions in [72].…”

Due to the dramatic increase in high data rate services and in order to meet the demands of the fifth-generation (5G) networks, researchers from both academia and industry are exploring advanced transmission techniques, new network architectures and new frequency spectrum such as the visible light and the millimeter wave (mmWave) spectra. Visible light communication (VLC) particularly is an emerging technology that has been introduced as a promising solution for 5G and beyond, owing to the large unexploited spectrum, which translates to significantly high data rates. Although VLC systems are more immune against interference and less susceptible to security vulnerabilities since light does not penetrate through walls, security issues arise naturally in VLC channels due to their open and broadcasting nature, compared to fiber-optic systems. In addition, since VLC is considered to be an enabling technology for 5G, and security is one of the 5G fundamental requirements, security issues should be carefully addressed and resolved in the VLC context. On the other hand, due to the success of physical layer security (PLS) in improving the security of radio-frequency (RF) wireless networks, extending such PLS techniques to VLC systems has been of great interest. Only two survey papers on security in VLC have been published in the literature. However, a comparative and unified survey on PLS for VLC from information theoretic and signal processing point of views is still missing. This paper covers almost all aspects of PLS for VLC, including different channel models, input distributions, network configurations, precoding/signaling strategies, and secrecy capacity and information rates. Furthermore, we propose a number of timely and open research directions for PLS-VLC systems, including the application of measurement-based indoor and outdoor channel models, incorporating user mobility and device orientation into the channel model, and combining VLC and RF systems to realize the potential of such technologies.

“…[19] developed the upper and lower bounds for the multiple-input multiple-output (MIMO) channel capacity under the idealized simplifying assumption of having perfect channel state information (CSI) at the transmitter. As one of the key techniques of achieving secrecy, the multi-LED based wiretap channel enjoyed particular attention [5], [20]- [23], where the associated high degree of freedom may be exploited by beamforming schemes [5], [22], [23] and artificial noise injection [20], [21], [24]. Specifically, the authors of [5] derived the lower and upper bounds on the capacity of the SISO Gaussian wiretap channel under continuous input distribution and amplitude constraints.…”

“…Then, robust secrecy-enhancing beamformers were designed for the secrecy rate maximization of a MISO VLC system, when either the CSI or the CSI-statistics of the eavesdropper was assumed to be perfectly known or imperfectly known [22], [23]. Alternatively, when considering MISO VLC systems, and when the eavesdropper's instantaneous CSI was not available at the transmitter, a friendly jammer was relied upon for transmitting jamming signals by a beamformer to maximize the secrecy rate [20], [21]. Furthermore, to enhance the communication secrecy, a scheme that jointly relies on both transmit beamforming and friendly jamming was proposed for a MISO VLC system operating in the face of multiple eavesdroppers [25].…”

“…In [5], [22] and [23], a continuous uniform distribution across a given interval was considered, while in [21] and [30] a truncated Gaussian distribution or its generalized form was assumed, where the design-objective was to increase the secrecy rate under a specific amplitude constraint of the input signal. However, the Gaussian input signal assumption is impractical due to its infinite peak power and excessive detection complexity.…”

Abstract-In order to enhance the secrecy performance of the Generalized Space Shift Keying (GSSK) visible light communication (VLC) system, in this paper, an optical jamming aided secrecy enhancement scheme is proposed, in which the source transmitter (S) simultaneously sends both the confidential desired signal and optical jamming signals under amplitude and power constraints. The optical jamming signals obey the truncated Gaussian distribution for satisfying the constraints. Given the discrete set of channel inputs, the optical jamming aided GSSK-VLC system's secrecy performance is analyzed. Explicitly, the average mutual information (AMI), the lower bound of AMI and its closed-form approximation as well as the achievable secrecy rate are formulated analytically. Furthermore, the optimal power sharing strategy of the proposed GSSK-VLC systems relying on optical jamming is derived. Closed-form expressions are provided for the optimal power sharing in both the low-and high-SNR regions. Finally, extensive simulation results are presented to validate our analytical results.Index Terms-Visible light communication (VLC), generalized space shift keying (GSSK), physical layer security (PLS), optical jamming, achievable secrecy rate, power sharing.

“…Recently, Mostafa et al analyzed the achievable secrecy rate for single-input single-output (SISO) and multiple-input single-output (MISO) scenarios and proposed a variety of beamforming schemes such as zero-forcing (null-steering), artificial noise generation, friendly jamming, and robust beamforming [11]- [13]. Additionally, Zaid and Arfaoui proposed the truncated normal input distribution and the truncated generalized normal input distribution, respectively, to increase the secrecy rate under constraints on the input signal amplitude [14], [15]. It is important to note, however, that these contributions assumed a small number of EDs are present in the system and either the channel state information (CSI) or the locations of the EDs Inspired by the aforementioned contributions exploiting stochastic geometry in RF communications, our previous work [16] firstly developed an analogous approach to modeling ED locations in VLC systems.…”

Abstract-This paper considers secrecy enhancement mechanisms in visible light communication (VLC) systems with spatially distributed passive eavesdroppers (EDs) under the assumption that there are multiple LED transmitters and one legitimate user equipment (UE). Based on certain amplitude constraints, we propose a beamforming scheme to improve secrecy performance. Contrary to the case where null-steering is made possible by using knowledge of the ED locations, the proposed beamforming when only statistical information about ED locations is available directs the transmission along a particular eigenmode related to the intensity of the ED process and the intended channel. Then, a LED selection scheme that is less complicated than beamforming is provided to reduce the secrecy outage probability (SOP). An approximate closed-form for the SOP is derived by using secrecy rate bounds. All the analysis is numerically verified by MonteCarlo simulations. The analysis shows that the beamformer yields superior performance to LED selection. However, LED selection is still a highly efficient alternative scheme due to the complexity associated with the use of multiple transmitters in the full beamforming approach. These performance trends and exact relations between system parameters can be used to develop a secure VLC system in the presence of randomly distributed EDs.Index Terms-Physical layer security, visible light communication, beamforming, stochastic geometry, secrecy outage probability.
