Secrecy capacity of LiFi systems [PDF]
Emerging Imaging and Sensing Technologies for Security and Defence V; and Advanced Manufacturing Technologies for Micro- and Nanosystems in Security and Defence III, 2020 Radio frequency (RF) signals propagate through most materials that we are surrounded by while light is blocked by many of these materials. This feature makes wireless networks based on light (which are also referred to as LiFi networks) inherently more secure.

Secrecy‐Capacity‐Optimization‐Artificial‐Noise in Large‐Scale MIMO: Ergodic Lower Bound on Secrecy Capacity and Optimal Power Allocation [PDF]
Wireless Communications and Mobile Computing, 2021 The security of wireless information transmission in large‐scale multi‐input and multioutput (MIMO) is the focus of research in wireless communication. Recently, a new artificial noise—SCO‐AN which shows no orthogonality to the channel, is proposed to overcome the shortcomings of traditional artificial noise.

On the Binary Input Gaussian Wiretap Channel with/without Output Quantization
Entropy, 2017 In this paper, we investigate the effect of output quantization on the secrecy capacity of the binary-input Gaussian wiretap channel. As a result, a closed-form expression with infinite summation terms of the secrecy capacity of the binary-input Gaussian

PHYSICAL LAYER SECRECY ON WIRELESS NETWORK
Tạp chí Khoa học Đại học Đà Lạt, 2016 In this paper, we present an approach for wireless security based on physical layer. The basic principle of physical layer secrecy (PHY Secrecy) is ensuring secure information transmission in the the system that consists of illegal receiver without using

On Physical Layer Security Over the Fisher-Snedecor
IEEE Access, 2018 In this paper, we initially investigate the physical layer security over device-to-device communications, where the channel is modeled from the Fisher-Snedecor .T distribution.
