Weightwise Perfectly Balanced Functions and Nonlinearity [PDF]

open access: yes, 2023
In this article we realize a general study on the nonlinearity of weightwise perfectly balanced (WPB) functions. First, we derive upper and lower bounds on the nonlinearity from this class of functions for all n. Then, we give a general construction that allows us to provably provide WPB functions with nonlinearity as low as 2 n/2−1 and WPB functions ...

On the linear structures of balanced functions and quadratic APN functions [PDF]

open access: yesCryptography and Communications, 2020
The set of linear structures of most known balanced Boolean functions is nontrivial. In this paper, some balanced Boolean functions whose set of linear structures is trivial are constructed. We show that any APN function in even dimension must have a component whose set of linear structures is trivial. We determine a general form for the number of bent

Existence of balanced functions that are not derivative of bent functions

open access: yes2023 XVIII International Symposium Problems of Redundancy in Information and Control Systems (REDUNDANCY), 2023
It is disproved the Tokareva's conjecture that any balanced boolean function of appropriate degree is a derivative of some bent function. This result is based on new upper bounds for the numbers of bent and plateaued functions.

Classification of Balanced Quadratic Functions

open access: yesIACR Transactions on Symmetric Cryptology, 2019
S-boxes, typically the only nonlinear part of a block cipher, are the heart of symmetric cryptographic primitives. They significantly impact the cryptographic strength and the implementation characteristics of an algorithm. Due to their simplicity, quadratic vectorial Boolean functions are preferred when efficient implementations for a variety of ...
