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.

Towards Analysable Chaos-based Cryptosystems: Constructing Difference Distribution Tables for Chaotic Maps

Journal of Informatics and Web Engineering
Chaos-based cryptography has yet to achieve practical, real-world applications despite extensive research. A major challenge is the difficulty in analysing the security of these cryptosystems, which often appear ad hoc in design.

A Novel YOLOv2‐Guided Region of Interest Encryption Framework Based on Elliptic Curve, DNA Computing and Chaotic Dynamics

IET Image Processing, Volume 20, Issue 1, January/December 2026.
This paper introduces a hybrid image encryption method that combines DNA coding, elliptic curve cryptography and chaotic systems to securely protect specific regions of interest identified by you only look once, version 2. The approach achieves high security through near‐ideal entropy and resilience against attacks, making it particularly suitable for ...

An Efficient and Fast Image Encryption Scheme Based on a Novel One‐Dimensional Hybrid Chaotic System

IET Image Processing, Volume 20, Issue 1, January/December 2026.
ABSTRACT Recently, images have been used widely in a variety of fields, including social media, the military and medicine. Sensitive images are often transmitted over insecure networks and chaotic maps offer effective cryptographic properties for securing these transmissions.

A Novel Hybrid Image Encryption Scheme Using Henon Map for Secure Image Communication

IET Information Security, Volume 2026, Issue 1, 2026.
The combination of chaos theory and cryptographic methodologies constitutes a pivotal aspect of the information security. Owing to certain attributes of images, like their large data capacity and significant redundancy, image encryption needs specialized techniques instead of conventional text encryption.

On relationship between differential/linear clustering effects and the number of active S-boxes in block ciphers

Cybersecurity
Differential cryptanalysis and linear cryptanalysis are the two best-known cryptanalysis techniques for symmetric-key primitives. Ensuring resistance to these attacks is critical for the security of block ciphers.

WENNKP: Investigating Weak IVs and Statistical Bias in Stream Ciphers via Weighted Ensemble Neural Network

IET Information Security, Volume 2026, Issue 1, 2026.
At EUROCRYPT 2024, recovering key bits via superpoly (over 20 trillion terms for 851‐round Trivium) hit a bottleneck due to its complexity. While existing machine learning (ML)‐based cryptanalysis has shown promise on block ciphers, applying it to stream ciphers is difficult due to rapid diffusion.

Commutative Cryptanalysis as a Generalization of Differential Cryptanalysis [PDF]

Recently, Baudrin et al. analyzed a special case of Wagner\u27s commutative diagram cryptanalysis, referred to as commutative cryptanalysis. For a family $(E_k)_k$ of permutations on a finite vector space $G$, commutative cryptanalysis exploits the ...
