Cryptanalysis of LowMC instances using single plaintext/ciphertext pair
IACR Transactions on Symmetric Cryptology, 2020 Arguably one of the main applications of the LowMC family ciphers is in the post-quantum signature scheme PICNIC. Although LowMC family ciphers have been studied from a cryptanalytic point of view before, none of these studies were directly concerned ...

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 ...

Cryptanalysis of ARMADILLO2 [PDF]
, 2011 ARMADILLO2 is the recommended variant of a multi-purpose cryptographic primitive dedicated to hardware which has been proposed by Badel et al. in [1]. In this paper we propose a meet-in-the-middle technique that allows us to invert the ARMADILLO2 function.

, 2008 . This paper considers a cryptanalytic approach called integral cryptanalysis. It can be seen as a dual to differential cryptanalysis and applies to ciphers not vulnerable to differential attacks.

IET Communications, Volume 20, Issue 1, January/December 2026.This paper proposes a novel lightweight certificateless public key authentication with keyword search (CPAEKS) scheme tailored for IIoT environments, effectively addressing data confidentiality and retrieval efficiency. The scheme resists frequency analysis attacks, removes reliance on bilinear pairings, and eliminates key escrow and certificate ...

Cryptanalysis of TWOPRIME [PDF]
, 1998 Ding et al [DNRS97] propose a stream generator based on several layers. We present several attacks. First, we observe that the non-surjectivity of a linear combination step allows us to recover half the key with minimal effort. Next, we show that the various bytes are insufficiently mixed by these layers, enabling an attack similar to those on two-loop

SHA-3 Design and Cryptanalysis Report [PDF]
, 2010 The competition to select a new secure hash function standard SHA-3 was initiated in response to surprising progress in the cryptanalysis of existing hash function constructions that started in 2004.

Biclique Cryptanalysis on the Full Crypton-256 and mCrypton-128
Journal of Applied Mathematics, 2014 Biclique cryptanalysis is an attack which reduces the computational complexity by finding a biclique which is a kind of bipartite graph. We show a single-key full-round attack of the Crypton-256 and mCrypton-128 by using biclique cryptanalysis.

IET Cyber-Physical Systems: Theory &Applications, Volume 11, Issue 1, January/December 2026.Recent proposals by Mahmood et al., Braeken et al., and Chaudhry et al. aimed at establishing secure communication in AMI, asserting their methods fulfil the requisite security criteria. This paper, however, reveals that each of these proposals exhibits security vulnerabilities and lacks sufficient features for deployment.
