On Best Erasure Wiretap Codes: Equivocation Matrices and Design Principles [PDF]

open access: yesEntropy
Physical-layer security can aid in establishing secure telecommunication networks including cellular, Internet of Things, and telemetry networks, among others. Channel sounding techniques and/or telemetry systems for reporting channel conditions, coupled

Encoding Individual Source Sequences for the Wiretap Channel [PDF]

open access: yesEntropy, 2021
We consider the problem of encoding a deterministic source sequence (i.e., individual sequence) for the degraded wiretap channel by means of an encoder and decoder that can both be implemented as finite-state machines.

Amplitude Constrained Vector Gaussian Wiretap Channel: Properties of the Secrecy-Capacity-Achieving Input Distribution [PDF]

open access: yesEntropy, 2023
This paper studies the secrecy capacity of an n-dimensional Gaussian wiretap channel under a peak power constraint. This work determines the largest peak power constraint R¯n, such that an input distribution uniformly distributed on a single sphere is ...

E - Capacity - Equivocation Region of Wiretap Channel [PDF]

open access: yesJournal of Universal Computer Science, 2021
One of the problems of information - theoretic security concerns secure communication over a wiretap channel. The aim in the general wiretap channel model is to maximize the rate of the reliable communication from the source to the legitimate receiver ...

Smoothing of Binary Codes, Uniform Distributions, and Applications [PDF]

open access: yesEntropy, 2023
The action of a noise operator on a code transforms it into a distribution on the respective space. Some common examples from information theory include Bernoulli noise acting on a code in the Hamming space and Gaussian noise acting on a lattice in the ...

Polar coding for the general wiretap channel [PDF]

open access: yes2015 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.

Enhancing secrecy rates in a wiretap channel

open access: yesDigital Communications and Networks, 2020
Reliable communication imposes an upper limit on the achievable rate, namely the Shannon capacity. Wyner's wiretap coding ensures a security constraint and reliability, but results in a decrease of achievable rate.

Sensing-Assisted Secure Communications over Correlated Rayleigh Fading Channels [PDF]

open access: yesEntropy
We consider a secure integrated sensing and communication (ISAC) scenario, where a signal is transmitted through a state-dependent wiretap channel with one legitimate receiver with which the transmitter communicates and one honest-but-curious target that

Improved polar-code-based efficient post-processing algorithm for quantum key distribution [PDF]

open access: yesScientific Reports, 2022
Combined with one-time pad encryption scheme, quantum key distribution guarantees the unconditional security of communication in theory. However, error correction and privacy amplification in the post-processing phase of quantum key distribution result ...

Secrecy Capacity of the Extended Wiretap Channel II with Noise

open access: yesEntropy, 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 ...
