Secrecy Rate Closed-Form Expressions for the SISO VLC Wiretap Channel With Discrete Input Signaling
IEEE Communications Letters, 2018We study in this letter the secrecy performance of a degraded single-input single-output visible-light communication wiretap channel. It has been shown in the literature that the secrecy capacity-achieving input distribution for this system is discrete ...

A statistical physics approach to the wiretap channel
2013 IEEE International Symposium on Information Theory, 2013The secrecy rate of Wyner wiretap channels is analyzed for general classes of sources, sensing schemes, and channel distributions. Using the replica method, heuristic closed form expressions are obtained for the asymptotic secrecy rate as a function of the statistics of the system model.

Explicit Codes for the Wiretap Channel with Uncertainty on the Eavesdropper's Channel
International Symposium on Information Theory, 2018We develop explicit codes for the wiretap channel when uncertainties hold on the eavesdropper's channel statistics. We do not require any symmetry or degradation assumptions on the channel and we do not require a pre-shared secret between the legitimate ...

Wiretap channel II with a noisy main channel
2015 IEEE International Symposium on Information Theory (ISIT), 2015In this paper, a wiretap channel where the transmitter and receiver communicate through a discrete memoryless channel, and the eavesdropper (Eve) has perfect access to a fixed fraction of transmitted symbols (of its choosing) is considered. An outer bound for the rate-equivocation region of the channel, for all such fractions, is derived. An achievable

LDPC Codes for the Gaussian Wiretap Channel
IEEE Transactions on Information Forensics and Security, 2009This paper presents a coding scheme for the Gaussian wiretap channel based on low-density parity-check (LDPC) codes. The messages are transmitted over punctured bits to hide data from eavesdroppers. The proposed coding scheme is asymptotically effective in the sense that it yields a bit-error rate (BER) very close to 0.5 for an eavesdropper whose ...

Optimal Beam Steering Design for Large-Scale mmWave MIMO Wiretap Channel
Global Communications Conference, 2018This paper investigates the optimal secure beam steering design of millimeter wave (mmWave) communications, where an Alice-Bob pair wishes to communicate in secret in the presence of Eve, with each node equipped with large-scale antenna arrays.
