On Matrix‐Based Cryptography Using Matrix Norm and Special Integer Sequences

Mathematische Nachrichten, Volume 299, Issue 8, Page 2087-2102, August 2026.
ABSTRACT In this paper, a novel matrix‐based encryption approach based on the Affine Hill cipher is presented. The key matrix is constructed using the Narayana integer sequence, and the Frobenius norm of the key matrix is used as a scaling factor in the key construction.

SiOx‐Based Probabilistic Bits Enabling Invertible Logic Gate for Cryptographic Applications

Advanced Intelligent Systems, Volume 8, Issue 7, July 2026.
To enable lightweight hardware encryption and decryption, a Ti/SiOx/Ti threshold switching device is engineered to generate controllable stochastic oscillations. By tuning the input voltage, the device produces a programmable spike probability governed by intrinsic switching dynamics, enabling probabilistic bits that construct an invertible ...

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 ...

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.
