Secrecy Capacity of the Extended Wiretap Channel II with Noise
Entropy, 2016 The secrecy capacity of an extended communication model of wiretap channelII is determined. In this channel model, the source message is encoded into a digital sequence of length N and transmitted to the legitimate receiver through a discrete memoryless ...

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

Strong Converse for a Degraded Wiretap Channel via Active Hypothesis Testing
, 2014 We establish an upper bound on the rate of codes for a wiretap channel with public feedback for a fixed probability of error and secrecy parameter. As a corollary, we obtain a strong converse for the capacity of a degraded wiretap channel with public ...

Polar coding for the general wiretap channel [PDF]
2015 IEEE Information Theory Workshop (ITW), 2015 Information-theoretic work for wiretap channels is mostly based on random coding schemes. Designing practical coding schemes to achieve information-theoretic security is an important problem. By applying the two recently developed techniques for polar codes, we propose a polar coding scheme to achieve the secrecy capacity of the general wiretap channel.

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 ...

Power Allocation in MIMO Wiretap Channel with Statistical CSI and Finite-Alphabet Input
, 2014 In this paper, we consider the problem of power allocation in MIMO wiretap channel for secrecy in the presence of multiple eavesdroppers. Perfect knowledge of the destination channel state information (CSI) and only the statistical knowledge of the ...
