The Secrecy Capacity of the MIMO Wiretap Channel [PDF]
IEEE Transactions on Information Theory, 2008 We consider the MIMO wiretap channel, that is a MIMO broadcast channel where the transmitter sends some confidential information to one user which is a legitimate receiver, while the other user is an eavesdropper. Perfect secrecy is achieved when the the transmitter and the legitimate receiver can communicate at some positive rate, while insuring that ...

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.

Finite-blocklength bounds for wiretap channels [PDF]
2016 IEEE International Symposium on Information Theory (ISIT), 2016 This paper investigates the maximal secrecy rate over a wiretap channel subject to reliability and secrecy constraints at a given blocklength. New achievability and converse bounds are derived, which are shown to be tighter than existing bounds. The bounds also lead to the tightest second-order coding rate for discrete memoryless and Gaussian wiretap ...

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 ...

Randomized Convolutional Codes for the Wiretap Channel [PDF]
IEEE Transactions on Communications, 2017 We study application of convolutional codes to the randomized encoding scheme introduced by Wyner as a way of confusing the eavesdropper over a wiretap channel. We describe optimal and practical sub-optimal decoders for the main and the eavesdropper’s channels, and estimate the security gap, which is used as the main metric.

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
