“…As expected, when E moves close to D, the achievable secrecy rate is significantly reduced. However, the achievable secrecy rate of the GSSK-VLC system increases rapidly, as E moves away from D. Additionally, when E is located at the symmetric regions of the projection of the transmitters, the achievable secrecy rate increases, which confirms the analytical results of [44]. In Fig.…”

“…5 that in most of the area considered, the SSK-VLC system achieves a relatively stable secrecy rate. However, as shown in [44], the achievable secrecy rate of the SSK-VLC system is zero in most of the scenarios considered, if no secrecy enhancement is utilized. The main reason behind this is that even for high SNRs, the detection performance of E can still be degraded by optical jamming, without affecting the reception performance of D, since the jamming signals are designed to lie in the null space of h D .…”

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.

“…Light energy harvesting and random positions were assumed for the one and only legitimate user and for an illegitimate user in the context of a hybrid VLC-RF system. Additionally, the secrecy performance of MISO generalized spaceshift keying (GSSK) aided VLC systems has been analyzed in [26] under certain constraints.…”

“…The authors showed that without extra secrecy enhancement strategy, illegal user can easily intercept the confidential signals at high SNR region, even if its channel condition is worse than the legal user. However, there is no particular practical strategy presented for enhancing the secrecy performance except for a suggested look-up table to select the optimal LEDs in [26].…”

In order to enhance the secrecy performance of the spatial modulation (SM) aided visible light communication (VLC) system, an optical jamming aided secrecy enhancement scheme is proposed in this paper, in which transmitter (Alice) sends the optical jamming signals and the confidential signal simultaneously with amplitude and power constraints, wherein the truncated Gaussian distribution is adopted by the optical jamming signals for the considered constraints. Additionally, with finite discrete support set of the channel inputs' distribution, the corresponding secrecy performance is systematically analyzed for the optical jamming aided SM-VLC system, which includes the average mutual information (AMI), the lower bound on AMI and its closedform expression approximation and the achievable secrecy rate. Furthermore, the power allocation problem for the proposed SM-VLC systems with optical jamming is considered. Finally, extensive simulation results are presented to validate our analytical results and the secrecy versus bit error ratio (BER) trade-off is characterized.
