Finding an Effective Metric Used for Bijective S-Box Generation by Genetic Algorithms [PDF]

, 2014
In cryptography, S-box is a basic component of symmetric key algorithms which performs nonlinear substitution. S-boxes need to be highly nonlinear, so that the cipher can resist linear cryptanalysis. The main criteria for cryptographically strong (n × n)

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.

Secured Low Power Overhead Compensator Look-Up-Table (LUT) Substitution Box (S-Box) Architecture [PDF]

2016 IEEE International Conference on Networking, Architecture and Storage (NAS), 2016
Substitution-Box (S-Box) is an important security building block for the Advanced Encryption Standard (AES) algorithm. However, its high power dissipation always compromises with its security feature under Correlation Power Analysis (CPA) attack. In this paper, we propose a secured and low power overhead LUT based S-Box architecture embodying a novel ...

The newfound relationship between extrachromosomal DNAs and excised signal circles

FEBS Letters, EarlyView.
Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

A novel design for the construction of safe S-boxes based on TDERC sequence

Alexandria Engineering Journal, 2015
The focus of this article is to construct substitution box based on tangent delay for elliptic cavity chaotic sequence and a particular permutation of symmetric group of permutations. The analysis result shows that the proposed S-box is very good against

Conserved structural motifs in PAS, LOV, and CRY proteins regulate circadian rhythms and are therapeutic targets

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.
