Cryptanalysis of the Sidelnikov Cryptosystem [PDF]
, 2007 We present a structural attack against the Sidelnikov cryptosystem [8]. The attack creates a private key from a given public key. Its running time is subexponential and is effective if the parameters of the Reed-Muller code allow for efficient sampling of minimum weight codewords. For example, the length 2048, 3rd-order Reed-Muller code as proposed in [

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.

An improvement of a cryptanalysis algorithm [PDF]
arXiv, 2014 In this paper we present experiments in order to show how some pseudo random number generators can improve the effectiveness of a statistical cryptanalysis algorithm. We deduce mainly that a better generator enhance the accuracy of the cryptanalysis algorithm.

IET Image Processing, Volume 18, Issue 14, Page 4589-4606, 11 December 2024.Randomness and sparse optimizations are applied to three floating‐point matrices obtained from discrete wavelet and sparse transforms of plain colour medical images. These matrices are then quantized into 8‐bit integer matrices and undergo deoxyribonucleic acid encoding, scrambling, XOR, and decoding to achieve base‐position scrambling and value ...

IACR Transactions on Symmetric CryptologyQARMAv2 is a general-purpose and hardware-oriented family of lightweight tweakable block ciphers (TBCs) introduced in ToSC 2023. QARMAv2, as a redesign of QARMAv1 with a longer tweak and tighter security margins, is also designed to be suitable for cryptographic memory protection and control flow integrity.

Key‐dependent side‐channel cube attack on CRAFT
ETRI Journal, 2021 CRAFT is a tweakable block cipher introduced in 2019 that aims to provide strong protection against differential fault analysis. In this paper, we show that CRAFT is vulnerable to side‐channel cube attacks.

CRYPTANALYSIS OF HYBRID CRYPTOSYSTEMS [PDF]
International Journal of Bifurcation and Chaos, 2013 An essential issue for the validation of ciphers is cryptanalysis, that is, the study of attacks in order to reveal possible weaknesses. In this paper, we propose a systematic and unified methodology for cryptanalyzing known chaos-based cryptosystems borrowed from the open literature, namely shift keying, discrete parameter modulation, switched ...
