A New Technique for Multidimensional Linear Cryptanalysis with Applications on Reduced Round Serpent [PDF]
, 2009 In this paper, we present a new technique for Matsui's algorithm 2 using multidimensional linear approximation. We show that the data complexity of the attack can be reduced significantly by our method even when the linear hull effect is present. We apply our method to the key recovery attack on 5-round Serpent and demonstrate that our attack is ...

Hyperchaos‐Driven 3D RGB Image Scrambling and Encryption for Multi‐Image Security
IET Image Processing, Volume 20, Issue 1, January/December 2026.The proposed encryption scheme scrambles N colour images by stacking them into a three‐dimensional red, green, blue image, generating a secure 256‐bit key using SHA‐256 and a user‐provided salt, and applying a five‐dimensional multi‐wing hyperchaotic system to produce random key streams.

IET Information Security, Volume 2026, Issue 1, 2026.At EUROCRYPT 2024, recovering key bits via superpoly (over 20 trillion terms for 851‐round Trivium) hit a bottleneck due to its complexity. While existing machine learning (ML)‐based cryptanalysis has shown promise on block ciphers, applying it to stream ciphers is difficult due to rapid diffusion.

Zero-Correlation Linear Cryptanalysis of Reduced-Round LBlock [PDF]
, 2012 Zero-correlation linear attack is a new method for cryptanalysis of block ciphers developed by Bogdanov et al. in 2012. In this paper we adapt the matrix method to find zero-correlation linear approximations.

Complexity, Volume 2024, Issue 1, 2024.Image encryption schemes are predominantly software‐based. Only a select few have been implemented in real‐life communication systems. This paper introduces a novel chaotic image encryption scheme based on a modified Z‐order curve, a modified Josephus problem, and an improved Vigenère cipher–based ribonucleic acid (RNA) operation. It is implemented and
