Evolving Dynamic S-Boxes Using Fractional-Order Hopfield Neural Network Based Scheme

open access: yesEntropy, 2020
Static substitution-boxes in fixed structured block ciphers may make the system vulnerable to cryptanalysis. However, key-dependent dynamic substitution-boxes (S-boxes) assume to improve the security and robustness of the whole cryptosystem.

Commutative Cryptanalysis Made Practical

open access: yesIACR Transactions on Symmetric Cryptology, 2023
About 20 years ago, Wagner showed that most of the (then) known techniques used in the cryptanalysis of block ciphers were particular cases of what he called commutative diagram cryptanalysis.

Comparison of Image Uniformity with Photon Counting and Conventional Scintillation Single-Photon Emission Computed Tomography System: A Monte Carlo Simulation Study

open access: yesNuclear Engineering and Technology, 2017
To avoid imaging artifacts and interpretation mistakes, an improvement of the uniformity in gamma camera systems is a very important point. We can expect excellent uniformity using cadmium zinc telluride (CZT) photon counting detector (PCD) because of ...

Mathematical Model of Uniform Cereal Crops Seeding Using a Double-Disk Coulter

open access: yesActa Technologica Agriculturae, 2020
The paper provided presents a new design of two-disk wide-row coulter that ensures uniform distribution of seeds to an even bed at the furrow bottom, as well as preserving of optimal distances between the seeds.

An Analog-Front ROIC with On-Chip Non-Uniformity Compensation for Diode-Based Infrared Image Sensors

open access: yesSensors, 2019
This paper proposes a CMOS front-end readout-integrated circuit (ROIC) with on-chip non-uniformity compensation technique for a diode-based uncooled infrared image sensor.

Measurement of laser differential confocal geometrical parameters for ICF capsule

open access: yesMatter and Radiation at Extremes, 2019
A method based on the laser differential confocal principle is proposed for measurement of the uniformity of the inner and outer radius and shell thickness for an inertial confinement fusion (ICF) capsule. Firstly, this method uses the laser differential

Maximal differential uniformity polynomials [PDF]

open access: yes, 2017
We provide an explicit infinite family of integers m such that all the polynomials of F2n [x] of degree m have maximal differential uniformity for n large enough.

The c-Differential-Linear Connectivity Table of Vectorial Boolean Functions

open access: yesEntropy
Vectorial Boolean functions and codes are closely related and interconnected. On the one hand, various requirements of binary linear codes are needed for their theoretical interests but, more importantly, for their practical applications (such as few ...
