A Novel Construction of Perfect Strict Avalanche Criterion S-box using Simple Irreducible Polynomials [PDF]
Scientific Journal of Informatics, 2020 An irreducible polynomial is one of the main components in building an S-box with an algebraic technique approach. The selection of the precise irreducible polynomial will determine the quality of the S-box produced. One method for determining good S-box

New Analysis Methods On Strict Avalanche Criterion Of S-Boxes
, 2008 S-boxes (Substitution boxes) are keystones of modern symmetric cryptosystems (block ciphers, as well as stream ciphers). S-boxes bring nonlinearity to cryptosystems and strengthen their cryptographic security. They are used for confusion in data security An S-box satisfies the strict avalanche criterion (SAC), if and only if for any single input bit of

Construction of highly nonlinear resilient Boolean functions satisfying strict avalanche criterion [PDF]
Science China Information Sciences, 2014 Boolean functions with high nonlinearity, high resiliency and strict avalanche criterion (SAC) play an important role in the designs of conventional cryptographic systems. In this paper, a method is proposed to construct resilient Boolean functions on n variables (n even) satisfying SAC with nonlinearity > 2n−1 − 2n/2.

A quantum algorithm to estimate the closeness to the Strict Avalanche criterion in Boolean functions [PDF]
CoRR, 2022 We propose a quantum algorithm (in the form of a quantum oracle) that estimates the closeness of a given Boolean function to one that satisfies the ``strict avalanche criterion'' (SAC). This algorithm requires $n$ queries of the Boolean function oracle, where $n$ is the number of input variables, this is fewer than the queries required by the classical

Relaxation of Strict Avalanche Criterion on All SHA-256 Sub-Function Combinations
CryptographyA cryptographic hash function should dissipate patterns, such that highly related inputs are transformed into unrelated outputs. This property, known as diffusion, has been effectively measured on SHA-256 via the Strict Avalanche Criterion (SAC ...
