Cryptanalysis of Round-Reduced Fantomas, Robin and iSCREAM

Cryptography, 2019
In this work, we focus on LS-design ciphers Fantomas, Robin, and iSCREAM. LS-designs are a family of bitslice ciphers aimed at efficient masked implementations against side-channel analysis.

Non-Linear Approximations in Linear Cryptanalysis [PDF]

, 1996
By considering the role of non-linear approximatioris in linear cryptanalysis we obtain a generalization of Matsui's linear cryptanalytic techniques. This approach allows Ihe cryptanalyst greater flexibility in mounting a linear cryptanalytic attack and we demonstrate the effectiveness of our non-linear techniques with some simple attacks on LOK191 ...

Distribusi Difference dari S-Box Berbasis Fungsi Balikan Pada GF(28)

Jurnal Matematika, 2016
Substitution-box (s-box) is a basic component of block cipher which performs a substitution. Two powerful cryptanalysis techniques applied to block ciphers are linear cryptanalysis and differential cryptanalysis.

Linear and differential cryptanalysis: Another viewpoint

Математические вопросы криптографии, 2020
Доказаны теоремы о точных значениях линейной и разностной характеристик. Приведен пример универсальной функциональной схемы, который показывает, что обычные методы оценки характеристик вероятностных соотношений могут приводить к значительным ошибкам.

Security analysis of an encryption scheme based on nonpositional polynomial notations

Open Engineering, 2016
The aim of the research was to conduct a cryptographic analysis of an encryption scheme developed on the basis of nonpositional polynomial notations to estimate the algorithm strength. Nonpositional polynomial notations (NPNs) are residue number systems (

FPGA Realization of a Novel Hyperchaos Augmented Image Encryption Algorithm

IET Computers &Digital Techniques, Volume 2026, Issue 1, 2026.
With the rapid growth of multimedia communication, protecting image data has become increasingly critical. This article proposes a novel 3‐stage hyperchaos‐based augmented image encryption technique (3SHAIET) that utilizes a three‐stage process with chaotic systems of increasing dimensionality (e.g., six‐dimensional [6D], 8D, and 9D) to enhance ...
