FPGA Realization of a Novel Hyperchaos Augmented Image Encryption Algorithm

IET Computers &Digital Techniques, Volume 2026, Issue 1, 2026.
With the rapid growth of multimedia communication, protecting image data has become increasingly critical. This article proposes a novel 3‐stage hyperchaos‐based augmented image encryption technique (3SHAIET) that utilizes a three‐stage process with chaotic systems of increasing dimensionality (e.g., six‐dimensional [6D], 8D, and 9D) to enhance ...

SKE2SG: A Secure Key Establishment Scheme for Smart Grid Cyber‐Physical Systems Based on Elliptic Curve Cryptography

IET Cyber-Physical Systems: Theory &Applications, Volume 11, Issue 1, January/December 2026.
Recent proposals by Mahmood et al., Braeken et al., and Chaudhry et al. aimed at establishing secure communication in AMI, asserting their methods fulfil the requisite security criteria. This paper, however, reveals that each of these proposals exhibits security vulnerabilities and lacks sufficient features for deployment.

A Comparative Study of Decision Tree, RNNs and CNNs for Detection of False Data Injection Attacks in Cyber‐Physical Power Systems

IET Cyber-Physical Systems: Theory &Applications, Volume 11, Issue 1, January/December 2026.
Intrusion detection for FDIAs is proposed using three approaches. (1) a stack‐based model containing an expansion decision tree and neural network, (2) recurrent neural networks (RNNs) and (3) convolutional neural networks (CNNs). The first two methods are based on the initial preprocessing of row instances, whereas the last one involves the time ...

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.
