A Multichaotic Map Approach to Image Encryption and Security Analysis

Journal of Computer Networks and Communications, Volume 2026, Issue 1, 2026.
Encryption remains one of the most effective techniques for securing digital data. Over the years, researchers have explored many image encryption schemes to enhance the security of data. Existing cryptosystems still struggle to maintain an ultimate balance between efficiency, security, and resistance to attacks. Digital images contain highly sensitive

Polynomial Representations of Weak Inverse Property Quasigroups and Their Role in Cryptographic Primitives

Journal of Mathematics, Volume 2026, Issue 1, 2026.
A connection between cryptography and polynomial functions is extremely significant. Mathematical performance of polynomials helps to enhance the cryptographic primitives, which are trustworthy as well as straightforward representation tools, in everyday use. In this research, explicit topological sequences Qf which correspond to degree‐based, distance‐

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.
