On the Binary Input Gaussian Wiretap Channel with/without Output Quantization

open access: yesEntropy, 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

open access: yesTạp 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

New Result on the Feedback Capacity of the Action-Dependent Dirty Paper Wiretap Channel

open access: yesEntropy, 2021
The Gaussian wiretap channel with noncausal state interference available at the transmitter, which is also called the dirty paper wiretap channel (DP-WTC), has been extensively studied in the literature. Recently, it has been shown that taking actions on

Hybrid Cache Placement for Physical-Layer Security in Cooperative Networks

open access: yesIEEE Access, 2018
Due to the broadcast nature of wireless transmission, traditional wireless two-hop relaying is vulnerable for eavesdroppers to overhear messages. In order to enhance the physical-layer security, this paper studies one cooperative network with caching ...

Secure Communications in SWIPT-Enabled Two-Way Relay Networks

open access: yesIEEE Access, 2019
This paper investigates the secrecy performance of a wireless-powered two-way relay network in the presence of an eavesdropper. Based on adaptive time allocation (TA) and power splitting (PS), a novel secure relaying protocol is proposed. For the purpose

A Coalitional Formation Game for Physical Layer Security of Cooperative Compressive Sensing Multi-Relay Networks

open access: yesSensors, 2018
Cooperative relaying is an effective technology to improve the capacity of physical-layer security, in which the relay helps forward the received signal to the destination. In this paper, a cooperative compressive sensing and amplify-and-forward (CCS-AF)

Some New Results on the GaussianWiretap Feedback Channel

open access: yesEntropy, 2019
In this paper, the Gaussian wiretap feedback channel is revisited, and some new resultson its secrecy capacity are obtained. To be specific, first, we show that the Schalkwijk−Kailath (SK)feedback scheme, which achieves the secrecy capacity of the ...
