“…Physical layer security has been regarded as a promising safeguard technology for wireless communications through utilizing the time-varying nature of the wireless fading channels [23], [24]. In the last several years, the secrecy performance of wireless fading systems was studied in many literatures [25]- [33]. In these great works, the fundamental theories of physical layer security were introduced and the state-of-the-art works on physical layer security technologies were provided.…”

“…Wireless systems are more vulnerable due to the broadcast nature of wireless communications, which is solved by adding keys to the application layer in traditional research. Recently, the physical layer security technology can securely transmit information through the orthogonal characteristics of the physical layer resources [1]. The ultra-dense network is one of the key technologies in the fifth generation mobile communication systems, where the frequency utilization and coverage are improved [2]; with the deployment of ultra-dense networks, the coverage and improvement of the system throughput are the main fields in the research on its performance and transmission technologies.…”

The distribution of the base stations (BSs) and users is mostly designed as a two-dimensional model in the study about heterogeneous networks (HetNets), which is not suitable for ultra-dense network scenarios. Meanwhile, the eavesdroppers existing in vertical dimension directly reduce the physical layer security of the HetNets. To tackle the mentioned problem, we propose to adjust the vertical dimension of the full-dimension (FD) antenna placed in the BSs; then the signal-to-noise ratios (SNRs) of the legitimate users and eavesdroppers are given due to the tilted angle. According to the three-dimensional Poisson point process (PPP) of BSs and users, the cumulative distribution function of SNR is deduced, which derives the closed expression of average security rate. The simulation results verify the correctness of the closed expression and the feasibility of proposed scenarios that the physical layer security performance can be improved by adjusting the vertical tilt angle. And density ratio of the BSs can be obtained in the various specific scenes.

“…As a complement to the conventional upper-layer solutions, such as cryptographic techniques, various physical layer secrecy (PLS) techniques have been proposed to provide perfect security in wireless communication systems [9]- [12], which were first studied in the context of wiretap channels by Wyner in [13] for point-to-point communication systems and later for broadcast channels by Csiszár and Körner in [14], and for Gaussian wiretap channels in [15]. These contributions focused on maximizing the data rate of secret communications, namely, the secrecy capacity of a wiretap channel where a source transmitter (S) is equipped with multiple antennas for confidentially communicating with a legitimate destination receiver (D), while a passive eavesdropper (E) is trying to wiretap the confidential information of S and D. PLS techniques have been applied to a wide range of RF wireless systems, which has improved the overall security by complementing existing classic cryptography-based techniques [10]. However, given the average optical power, the peak optical power and the electrical power constraints imposed on the VLC signals, these techniques developed for RF wireless communication systems cannot be directly transplanted into practical VLC scenarios.…”

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.
