Finding efficient distinguishers for cryptographic mappings, with an application to the block cipher TEA [PDF]

, 2003
Congress on Evolutionary Computation. 8-12 December 2003A simple way of creating new and efficient distinguishers for cryptographic primitives such as block ciphers or hash functions is introduced. This technique is then successfully applied over reduced

Improvement of the Minimal‐Guess‐Basis MILP Model and Its Application to ESF

IET Information Security, Volume 2026, Issue 1, 2026.
The guess‐and‐determine technique find wide applications in the recovery of unknown variables within given system of relations. The fundamental concept behind this technique involves guessing certain unknown variables and deducing the remaining ones based on the relational system.

A Type of Differential Fault Attacks of the Stream Cipher SNOW‐V Based on AES Structure

IET Information Security, Volume 2026, Issue 1, 2026.
SNOW‐V is a member in the SNOW family of stream ciphers designed for the 5G mobile communication system. In order to have a high speed, both the linear feedback shift register (LFSR) and finite state machine (FSM) are updated to better align with vectorized implementations and the update function is based on the round function of AES. In this paper, we

Towards Analyzable Design Paradigms for Chaos-Based Cryptographic Primitives

Journal of Cybersecurity and Privacy
Although many chaos-based cryptosystems have been proposed over the past decade, they have yet to gain traction in real-world applications. A key reason for this is that most designs rely on security through obscurity, with unnecessarily complex ...

A Hybrid Matrix–Based Encoding Scheme With Error Detection via Third‐Order Recurrences

Journal of Mathematics, Volume 2026, Issue 1, 2026.
In this paper, we propose a novel encoding–decoding algorithm based on third‐order linear recurrence sequences and their associated matrix representations. In particular, third‐order Jacobsthal and third‐order Jacobsthal–Lucas matrix sequences are combined with Padovan and Perrin matrix sequences to construct a hybrid block–based coding scheme.

Integral and impossible‐differential attacks on the reduced‐round Lesamnta‐LW‐BC

IET Information Security, 2022
Lesamnta‐LW‐BC is the internal block cipher of the Lesamnta‐LW lightweight hash function, specified in ISO/IEC 29192‐5:2016. It is based on the unbalanced Feistel network and Advanced Encryption Standard round function.

Metabolism of Epoxidised Withanolides by a Generalist and a Specialist Insect Species

ChemistryOpen, Volume 14, Issue 12, December 2025.
Larvae of Heliothis (Chloridea) virescence and subflexa have the ability to convert the epoxidized terpenoid 4β‐hydroxywithanolide E (4BHWE) to withanolide S. The conversion is found by feeding the larvae an artificial diet supplemented with 13C‐labeled 4BHWE.

Analysis of Diffusion Properties in Generalized Feistel Ciphers Under Multidimensional Linear Cryptanalysis

IACR Transactions on Symmetric Cryptology
This paper presents a unified framework for generic attacks on Generalized Feistel Ciphers, with a primary focus on Type 1, Type 2, and unbalanced contracting (U-Type 1) Feistel constructions with non-invertible round functions.

A Brief Note on Supercooled Glacial Deep Waters

Paleoceanography and Paleoclimatology, Volume 40, Issue 12, December 2025.
Abstract According to hydrographic profiles, approximately 2%–5% of the present‐day deep Southern Ocean contains supercooled waters that are below the freezing point. Which role these supercooled waters may have played under glacial conditions is an open question.

Oxygen Isotope Insights Into the Impact of Amundsen Sea Freshwater on Ross Sea Freshening

Geophysical Research Letters, Volume 52, Issue 22, 28 November 2025.
Abstract Over the past five decades, the Ross Sea has freshened, but the mechanisms remain unclear. This study uses oxygen isotopes to trace freshwater transport from the Amundsen Sea to the Ross Sea. Results show that Winter Water (WW) in the Antarctic Slope Current (ASC) has lower δ18O values (<−0.7‰) due to glacial meltwater (GMW) inputs from the ...
