Hyperchaos‐Driven 3D RGB Image Scrambling and Encryption for Multi‐Image Security

IET Image Processing, Volume 20, Issue 1, January/December 2026.
The proposed encryption scheme scrambles N colour images by stacking them into a three‐dimensional red, green, blue image, generating a secure 256‐bit key using SHA‐256 and a user‐provided salt, and applying a five‐dimensional multi‐wing hyperchaotic system to produce random key streams.

Enhancing E‐Commerce Security Based on Involution Function Using Twin Key AES Cipher

IET Information Security, Volume 2026, Issue 1, 2026.
In the realm of surging e‐commerce data and increasing digital transactions, ensuring end‐to‐end security is paramount to protect sensitive information and maintain user trust. The Advanced Encryption Standard (AES), a cornerstone of network security, relies on symmetric key encryption for secure communication.

Resisting Quantum Key Distribution Attacks Using Quantum Machine Learning

IET Quantum Communication, Volume 7, Issue 1, January/December 2026.
Quantum key distribution (QKD) promises secure communication but remains vulnerable to advanced quantum attacks. We propose a hybrid quantum long short‐term memory (QLSTM) model that combines quantum‐enhanced learning with classical deep learning to detect attacks such as photon‐number splitting, Trojan‐Horse and detector blinding.

Fair Public-Key Cryptosystems [PDF]

, 2007
We show how to construct public-key cryptosystems that are fair, that is, strike a good balance, in a democratic country, between the needs of the Government and those of the Citizens. Fair public-key cryptosystems guarantee that: (1) the system cannot be misused by criminal organizations and (2) the Citizens mantarn exactly the same rights to privacy ...

Safe and Quickest Medical Image Encryption Using Logistic Map Derived S‐Boxes and Galois Field

Computational and Mathematical Methods, Volume 2026, Issue 1, 2026.
The pseudorandomness, simplicity of use, and extreme sensitivity to even the slightest change in the initial value and handling parameters make chaotic maps attractive. The use of medical imaging to diagnose illnesses has grown in significance. These photographs need strong security measures because they are exchanged over public networks.
