Secret Sharing over Fast-Fading MIMO Wiretap Channels
EURASIP Journal on Wireless Communications and Networking, 2009 Secret sharing over the fast-fading MIMO wiretap channel is considered. A source and a destination try to share secret information over a fast-fading MIMO channel in the presence of an eavesdropper who also makes channel observations that are different ...

IEEE Access, 2018 In this paper, we investigate the secrecy performance of dual-hop randomize-and-forward (RaF) cognitive relay multi-channel wiretap networks over correlated fading channels, in which the eavesdropper can wiretap the information from source and relays ...

Secrecy Capacity of a Class of Broadcast Channels with an Eavesdropper
EURASIP Journal on Wireless Communications and Networking, 2009 We study the security of communication between a single transmitter and many receivers in the presence of an eavesdropper for several special classes of broadcast channels. As the first model, we consider the degraded multireceiver wiretap channel where

Secrecy Rate Region Enhancement in Multiple Access Wiretap Channel
Journal of Telecommunications and Information Technology, 2022 It is commonly known that physical layer security is achieved with a trade-off in terms of the achievable rate. Hence, security constraints generate rate losses in wiretap channels.

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

Polar Coding for Confidential Broadcasting
Entropy, 2020 A polar coding scheme is proposed for the Wiretap Broadcast Channel with two legitimate receivers and one eavesdropper. We consider a model in which the transmitter wishes to send the same private (non-confidential) message and the same confidential ...

A New Physical Layer Security Scheme Based on Adaptive Bit Channel Selection for Polar-Coded OFDM
IEEE Open Journal of Vehicular TechnologyWe propose a new physical layer security scheme for a wiretap channel in polar-coded OFDM-based wireless communication systems. Our approach is based on the adaptive bit channel selection, where the input bit channels of polar code are selected according

IEEE Photonics Journal, 2018 When an eavesdropper performs an optical beam-splitting attack in a free-space optical communications channel, it is referred to as an optical wiretap channel, which is an extension of Wyner's wiretap channel model.

Classical -Quantum Multiple Access Channel with Secrecy Constraint: One-shot Rate Region
International Journal of Information and Communication Technology Research, 2020 In this paper, we aim to study a -user quantum multiple access wiretap channel with an arbitrary number of wiretappers under one-shot setting. In this regard, we first introduce the general quantum multiple access wiretap channel and the simplified ...
