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 ...

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.

Healthcare Technology Letters, Volume 13, Issue 1, January/December 2026.This paper proposes a secure electrocardiogram (ECG)‐processing framework that digitises ECG waveforms from clinical paper or image‐based records and encrypts them using a dual chaotic cryptographic scheme. The method supports both extracted and native digital signals, ensuring strong security and interoperability for Internet of Medical Things ...

Generating Graphs Packed with Paths Estimation of Linear Approximations and Differentials
IACR Transactions on Symmetric Cryptology, 2018 When designing a new symmetric-key primitive, the designer must show resistance to known attacks. Perhaps most prominent amongst these are linear and differential cryptanalysis. However, it is notoriously difficult to accurately demonstrate e.g.

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.
