Impact of Cyberphysical Attacks on Load Tap Changers and Distribution System Voltage Stability
IET Smart Grid, Volume 9, Issue 1, January/December 2026.In this paper, we analysed the impact of a cyberphysical attack manipulating the operation of the LTC. In addition, we analysed the effect of load drop and PV while LTC is being manipulated. The cyber vulnerabilities leading to the attack were explored. ABSTRACT Load tap changers (LTCs) play a critical role in voltage regulation, and their manipulation

New Phytologist, Volume 249, Issue 2, Page 945-960, January 2026.Summary Monoterpene indole alkaloids (MIA) are a diverse class of plant natural products produced by a subset of lineages within the Asterid clade of eudicots. The diversity of MIAs provides a unique opportunity to study not only the evolution of biosynthetic genes but also their regulation.

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.

Securing End‐To‐End Encrypted File Sharing Services With the Messaging Layer Security Protocol
Concurrency and Computation: Practice and Experience, Volume 37, Issue 27-28, 25 December 2025.ABSTRACT Secure file sharing is essential in today's digital environment, yet many systems remain vulnerable: if an attacker steals client keys, they can often decrypt both past and future content. To address this challenge, we propose a novel file‐sharing architecture that strengthens post‐compromise security while remaining practical.

Advanced Science, Volume 12, Issue 46, December 11, 2025.This study proposed physical unclonable function based multi‐level key space generation scheme. By exploiting speckle characteristic, a size‐controllable structure is achieved and that is suitable foundation for multiple key extraction. The flexible key space supports various specifications for advanced applications, such as hierarchical authentication

On Distinct Known Plaintext Attacks
, 2016 Among statistical attacks, we often make a distinction between attacks in the linear context, for which the knowledge of plaintexts and corresponding ciphertexts is enough to perform the attack, and attacks in the differential context, for which the plaintexts are chosen. Such attacks are usually referred as known-or chosen-plaintext attacks.
