Trinomials with high differential uniformity [PDF]
The context of this work is the study of the differential uniformity of polynomials defined over finite fields of even characteristic. We provide infinite families of trinomials with high differential uniformity when the base field is large enough.

cc-differential uniformity, (almost) perfect cc-nonlinearity, and equivalences [PDF]
, 2023 In this article, we introduce new notions $cc$-differential uniformity, $cc$-differential spectrum, PccN functions and APccN functions, and investigate their properties. We also introduce $c$-CCZ equivalence, $c$-EA equivalence, and $c1$-equivalence.

Bivariate functions with low $c$-differential uniformity [PDF]
, 2022 Starting with the multiplication of elements in $\mathbb{F}_{q}^2$ which is consistent with that over $\mathbb{F}_{q^2}$, where $q$ is a prime power, via some identification of the two environments, we investigate the $c$-differential uniformity for ...

Low c-differential uniformity for functions modified on subfields [PDF]
, 2021 In this paper, we construct some piecewise defined functions, and study their c-differential uniformity. As a by-product, we improve upon several prior results.

Differentially 4-Uniform Permutations with the Best Known Nonlinearity from Butterflies
IACR Transactions on Symmetric Cryptology, 2017 Many block ciphers use permutations defined over the finite field F22k with low differential uniformity, high nonlinearity, and high algebraic degree to provide confusion. Due to the lack of knowledge about the existence of almost perfect nonlinear (APN)

Investigation of Some Cryptographic Properties of the 8x8 S-boxes Created by Quasigroups [PDF]
Computer Science Journal of Moldova, 2020 We investigate several cryptographic properties in 8-bit S-boxes obtained by quasigroups of order 4 and 16 with several different algebraic constructions.

Emitter discharge variability of subsurface drip irrigation in uniform soils: effect on water-application uniformity [PDF]
, 2008 Emitter discharge of subsurface drip irrigation (SDI) decreases as a result of the overpressure in the soil water at the discharge orifice. In this paper, the variation in dripper discharge in SDI laterals is studied.

A New Hyperchaotic System-Based Design for Efficient Bijective Substitution-Boxes
Entropy, 2018 In this paper, we present a novel method to construct cryptographically strong bijective substitution-boxes based on the complicated dynamics of a new hyperchaotic system.
