Enabling secure data transmission for wireless sensor networks based IoT applications

Ain Shams Engineering Journal, 2023
The high volume of sensed and transferred data among nodes on wireless sensor networks makes it necessary to keep the data safe. This study offers an improved security mechanism, taking the application, security level, and bit error rate into account for

A new modified DES algorithm based on the development of binary encryption functions

Journal of King Saud University: Computer and Information Sciences, 2023
One of the most commonly used symmetric encryption methods is the Data Encryption Standard (DES), but it has a number of flaws. For instance, the encryption method only employs two functions (XOR), acts on one bit, and only allows for a finite number of ...

Higher-order differences based research on comparison between type-1 generalized Feistel-SP network and Feistel-SPSP network

Tongxin xuebao, 2014
The powers against the higher-order differential cryptanalysis of the single-SP(substitution-permutation) model and the double-SP model are studied in the type-1 Feistel network by analyzing the growths of algebraic degrees.

The Influence of Topography and Crustal Magnetic Anomalies on the Distribution of Water Ice in the Lunar South Pole Region

Journal of Geophysical Research: Planets, Volume 131, Issue 7, July 2026.
Abstract Lunar magnetic anomalies are abundant near the south pole, where several moderate‐strength anomalies spatially overlap permanently shadowed regions (PSRs). This environment provides a unique setting to assess how crustal magnetic fields and topography regulate plasma–surface interactions and, in turn, the stability and distribution of surface ...

General Diffusion Analysis: How to Find Optimal Permutations for Generalized Type-II Feistel Schemes

IACR Transactions on Symmetric Cryptology, 2019
Type-II Generalized Feistel Schemes are one of the most popular versions of Generalized Feistel Schemes. Their round function consists in applying a classical Feistel transformation to p sub-blocks of two consecutive words and then shifting the k = 2p ...

Similarity Property and Slide Attack of Block Cipher FESH

IET Information Security, 2023
This paper focuses on similarity properties and extension of the classical slide property of block ciphers. Taking FESH, an award-winning block cipher of the National Cryptographic Algorithm Design Competition 2019, as an example, similarity properties ...

Impact of Moist Thermodynamic Formulations on Climatological Temperature Fields in a Global Cloud‐Resolving Model

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 6, June 2026.
Abstract This study investigates how climatological temperature fields in simulations are influenced by the choice of moist thermodynamic formulations. Two formulations were compared: one developed to ensure internal thermodynamic consistency, and a simpler approximation similar to those commonly used in meteorological and climate models.

US–China Trade War: The Effects of Trade Conflict on Brazilian Exports

The World Economy, Volume 49, Issue 6, Page 1293-1313, June 2026.
ABSTRACT Protectionist practices and their implications have been extensively studied in the literature, but few studies have examined the effects of trade competition between two countries on a third country. This paper aims to investigate how a demand shock triggered by China's retaliation against US exports affects Brazil's exports to China.

Improved Search of Boomerang Distinguishers for Generalized Feistel and Application to WARP

IACR Transactions on Symmetric Cryptology
Boomerang and rectangle cryptanalysis are powerful cryptanalytic techniques for security evaluation of block ciphers. Automated search for boomerang distinguishers is an important area of research. In FSE 2023, Hadipour et al.

Tweakable Pseudorandom Permutation from Generalized Feistel Structure

IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences, 2008
Tweakable pseudorandom permutations have wide applications such as the disk sector encryption, and the underlying primitive for efficient MACs and authenticated encryption schemes. Goldenberg et al. showed constructions of a tweakable pseudorandom permutation based on the Feistel structure.
