Resource‐Efficient Quantum Circuit Design for Reversible Logic Implementation

Quantum Engineering, Volume 2026, Issue 1, 2026.
In this work, we develop quantum reversible counterparts of the logical AND, NAND, OR, NOR, and XOR gates within a single architectural template: a quantum Fourier transform (QFT)–based adder that emulates a digital half‐adder by computing the sum and carry of two input bits.

Key Generation Using Generalized Pell’s Equation in Public Key Cryptography Based on the Prime Fake Modulus Principle to Image Encryption and Its Security Analysis

Cybernetics and Information Technologies, 2020
RSA is one among the most popular public key cryptographic algorithm for security systems. It is explored in the results that RSA is prone to factorization problem, since it is sharing common modulus and public key exponent.

Yet Another Algebraic Cryptanalysis of Small Scale Variants of AES [PDF]

, 2022
This work presents new advances in algebraic cryptanalysis of small scale derivatives of AES. We model the cipher as a system of polynomial equations over GF(2), which involves only the variables of the initial key, and we subsequently attempt to solve ...

A new S-box pattern generation based on chaotic enhanced logistic map: case of 5-bit S-box

Cybersecurity
Cryptography plays consistently an essential role in securing any sort of communications or data broadcast over the network. Since the security of any designed block cipher algorithm is related to its Substitution box (S-box), several efforts have been ...
