Key-controlled Rijndael algorithm with multiple S-boxes

Tongxin xuebao, 2007
According to the design criterion of S-box in Rijndael algorithm,a number of S-boxes with good crypto-graphic properties were constructed,and the avalanche probabilities of these S-boxes were analyzed from variance point of view.Based on these studies,a ...

A Quantum Differential Attack on ChaCha and Related Resources Estimation

IEEE Access
Existing classical cryptanalytic techniques against ChaCha primarily rely on differential cryptanalysis, leveraging probabilistic neutral bits (PNBs) introduced by Aumasson et al. Separately, Bathe et al.

Cell wall target fragment discovery using a low‐cost, minimal fragment library

FEBS Letters, EarlyView.
LoCoFrag100 is a fragment library made up of 100 different compounds. Similarity between the fragments is minimized and 10 different fragments are mixed into a single cocktail, which is soaked to protein crystals. These crystals are analysed by X‐ray crystallography, revealing the binding modes of the bound fragment ligands.

Meta-dynamical adaptive systems and their applications to a fractal algorithm and a biological model

, 2007
In this article, one defines two models of adaptive systems: the meta-dynamical adaptive system using the notion of Kalman dynamical systems and the adaptive differential equations using the notion of variable dimension spaces.

Attacking convolutional neural network using differential evolution [PDF]

IPSJ Transactions on Computer Vision and Applications, 2019
Abstract The output of convolutional neural networks (CNNs) has been shown to be discontinuous which can make the CNN image classifier vulnerable to small well-tuned artificial perturbation. That is, images modified by conducting such alteration (i.e., adversarial perturbation) that make little difference to the human eyes can completely

Structural biology of ferritin nanocages

FEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Quantum Free-Start Collision Attacks on Double Block Length Hashing with Round-Reduced AES-256

IACR Transactions on Symmetric Cryptology, 2021
Recently, Hosoyamada and Sasaki (EUROCRYPT 2020), and Xiaoyang Dong et al. (ASIACRYPT 2020) proposed quantum collision attacks against AES-like hashing modes AES-MMO and AES-MP.

Improved Differential Attacks on RC5 [PDF]

, 1996
In this paper we investigate the strength of the secret-key algorithm RC5 newly proposed by Ron Rivest. The target version of RC5 works on words of 32 bits, has 12 rounds and a user-selected key of 128 bits. At Crypto'95 Kaliski and Yin estimated the strength of RC5 by differential and linear cryptanalysis.

Organ‐specific redox imbalances in spinal muscular atrophy mice are partially rescued by SMN antisense oligonucleotides

FEBS Letters, EarlyView.
We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...

Conditional differential analysis on the KATAN ciphers based on deep learning

IET Information Security, 2023
KATAN ciphers are block ciphers using non‐linear feedback shift registers. In this study, the authors improve the results of conditional differential analysis on KATAN by using deep learning.
