Complexity, 2018 This paper proposes a novel method of constructing strong substitution-boxes (S-boxes) of order n (4 ≤ n ≤ 8) based on a recent optimization algorithm known as sine-cosine algorithm (SCA). The paper also proposes a new 1D chaotic map, which owns enhanced

COMPUTING AND INFORMATICS, 2012 Summary: It is well known that there does not exist a Boolean function \( f\:\mathbb Z^m_2\to \mathbb Z^n_2\) satisfying both basic cryptologic criteria, balancedness and perfect nonlinearity. Previously, \textit{O.~Grošek, L.~ Satko} and \textit{K.~Nemoga} [``Ideal difference tables from an algebraic point of view'', in: P. Caballero-Gil et al. (eds.),

Исследование свойств подстановок ГОСТ 28147-89, построенных на основе анализа свойств координатных функций [PDF]
, 2002 It is shown, that known requirements to S boxes of GOST 28147-89 allow to use permutations, which make cipher vulnerable to differential cryptanalysis.Показано, что известные требования к подстановкам ГОСТ 28147-89 позволяют использовать заполнение узлов

Integration of circadian and hypoxia signaling via non‐canonical heterodimerization
FEBS Letters, EarlyView.CLOCK, BMAL1, and HIFs are basic helix‐loop‐helix and Per‐Arnt‐Sim domain (bHLH‐PAS) proteins, which function as transcription factors. bHLH‐PAS proteins are designated in two classes. Many class I proteins are regulated by environmental signals via their PAS domains, but such signals have not been identified for all.

Systematic Review of Image Encryption Using Dynamic Encryption Techniques: an Article Review
Ibn Al-Haitham Journal for Pure and Applied Sciences, 2023 In this study, a chaotic method is proposed that generates S-boxes similar to AES S-boxes with the help of a private key belonging to the user and enables images to be encrypted or decrypted using S-boxes. The proposed method consists of two stages. The

Time after time – circadian clocks through the lens of oscillator theory
FEBS Letters, EarlyView.Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

On the Derivative Imbalance and Ambiguity of Functions
, 2018 In 2007, Carlet and Ding introduced two parameters, denoted by $Nb_F$ and $NB_F$, quantifying respectively the balancedness of general functions $F$ between finite Abelian groups and the (global) balancedness of their derivatives $D_a F(x)=F(x+a)-F(x)$, $

FEBS Letters, EarlyView.Cryptochrome and PAS/LOV proteins play intricate roles in circadian clocks where they act as both sensors and mediators of protein–protein interactions. Their ubiquitous presence in signaling networks has positioned them as targets for small‐molecule therapeutics. This review provides a structural introduction to these protein families.
