Secure, reliable, and efficient communication over the wiretap channel [PDF]

open access: yes, 2022
Secure wireless communication between devices is essential for modern communication systems. Physical-layer security over the wiretap channel may provide an additional level of secrecy beyond the current cryptographic approaches.

Physical-Layer Security of a Binary Data Sequence Transmitted With Bessel–Gaussian Beams Over an Optical Wiretap Channel

open access: yesIEEE 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.

Enhancing secrecy capacity of multi-relay wiretap systems with partial channel state information

open access: yes, 2015
Distributed precoding has provento be capable of enhancing the secrecy capacity of the multi-relay wiretap system. An iterative distributed precoding and channel state information (CSI) sharing scheme can be used to reduce the CSI overhead at each relay ...

Classical -Quantum Multiple Access Channel with Secrecy Constraint: One-shot Rate Region

open access: yesInternational 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 ...

An Efficient Advantage Distillation Scheme for Bidirectional Secret-Key Agreement

open access: yesEntropy, 2017
The classical secret-key agreement (SKA) scheme includes three phases: (a) advantage distillation (AD), (b) reconciliation, and (c) privacy amplification.

A Cryptographic Treatment of the Wiretap Channel

open access: yesIACR Cryptol. ePrint Arch., 2012
The wiretap channel is a setting where one aims to provide information-theoretic privacy of communicated data based solely on the assumption that the channel from sender to adversary is "noisier" than the channel from sender to receiver. It has been the subject of decades of work in the information and coding (I&C) community. This paper bridges the

Value of MRI Outcomes for Preventive and Early‐Stage Trials in Spinocerebellar Ataxias 1 and 3

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To examine the value of MRI outcomes as endpoints for preventive and early‐stage trials of two polyglutamine spinocerebellar ataxias (SCAs). Methods A cohort of 100 participants (23 SCA1, 63 SCA3, median Scale for the Assessment and Rating of Ataxia (SARA) score = 5, 42% preataxic, and 14 gene‐negative controls) was scanned at 3T up ...

Explicit capacity-achieving coding scheme for the Gaussian wiretap channel

open access: yes, 2014
—We extend the Bellare-Tessaro coding scheme for a discrete, degraded, symmetric wiretap channel to a Gaussian wiretap channel. Denoting by SNR the signal-to-noise ratio of the eavesdropper’s channel, the proposed scheme converts a transmission code of ...
