Artificial Noise-Based Beamforming for the MISO VLC Wiretap Channel

IEEE Transactions on Communications, 2019
This paper investigates the secrecy performance of the multiple-input single-output visible light communication (VLC) wiretap channel. The considered system model comprises three nodes: a transmitter (Alice) equipped with multiple fixtures of LEDs, a ...

Wiretap Channel with Correlated Sources

2014 IEEE International Conference on Cloud Engineering, 2014
This paper studies the problem of secret-message transmission over a wiretap channel with correlated sources in the presence of an eavesdropper who has no source observation. A coding scheme is proposed based on a careful combination of 1) Wyner-Ziv's source coding to generate secret key from correlated sources based on a certain cost on the channel, 2)

Wiretap channel with shared key

2010 IEEE Information Theory Workshop, 2010
This paper studies the problem of secure communication over a wiretap channel where the transmitter and the legitimate receiver share a secret key, which is concealed from the eavesdropper. We find the secrecy capacity under this scenario. This result generalizes that of Yamamoto, which is applicable only to less noisy wiretap channels, to the general ...

Codebook-Based Hybrid Beamforming Design for MISOME Wiretap Channel

IEEE Wireless Communications Letters, 2019
For practical implementation of multi-input multi-output systems, hybrid analog-digital beamforming may address the challenges of hardware limitation in fully digital beamforming (FDB).

Classical-Quantum Multiple Access Wiretap Channel

2019 16th International ISC (Iranian Society of Cryptology) Conference on Information Security and Cryptology (ISCISC), 2019
In this paper, the quantum wiretap channel (QWTC) and quantum multiple access channel (QMAC) are used so as to introduce the classical-quantum multiple access wiretap channel (C-QMA-WTC).

Wiretap channels with random states

2017 51st Annual Conference on Information Sciences and Systems (CISS), 2017
We propose a new encoding scheme for the wiretap channels with a random state known non-causally to the encoder but not necessarily to the decoder (the Gelfand-Pinsker setting). This setting combines two scenarios with celebrated results in information theory-the wiretap channel and the Gelfand-Pinsker channel-and it so happens that essentially the ...

Performance analysis of FSO/CDMA system based on binary symmetric wiretap channel

IET Communications, 2019
Transmission reliability, security, and efficiency are of great importance to free space optical (FSO) communication. For the first time, the authors obtain optimal parameters for the FSO/code division multiple access (CDMA) system taking into account ...

On the MISO compound wiretap channel

2010 Information Theory and Applications Workshop (ITA), 2010
We study the secure degrees of freedom (d.o.f.) of the MISO compound wiretap channel. The transmitter has M antennas, whereas the legitimate receiver and the eavesdropper each have one antenna and the channel vectors take one of finitely many values. If the number of states of either the legitimate receiver or the eavesdropper channel is less than M ...

Optical Wiretap Channel With Input-Dependent Gaussian Noise Under Peak- and Average-Intensity Constraints

IEEE Transactions on Information Theory, 2018
This paper studies the optical wiretap channel with input-dependent Gaussian noise, in which the main distortion is caused by an additive Gaussian noise whose variance depends on the current signal strength.

Codes for wireless wiretap channels

2014 IEEE Information Theory Workshop (ITW 2014), 2014
In this presentation we are interested in coding for wiretap wireless channels. First part is devoted to design criteria, second part will deal with the codes themselves. Nested lattices are the main ingredients to be used. We start with the Gaussian wiretap channel where it is shown that theta series have to be minimized.
