Multiset Structural Attack on Generalized Feistel Networks [PDF]

Mathematical Problems in Engineering, 2019
In this paper, we present new generic multiset attacks against generalized Feistel networks, by which we can recover all the unknown round functions completely instead of deciding whether an unknown encryption oracle is such network or a random permutation.

SAT-Based Security Evaluation for WARP against Linear Cryptanalysis

IET Information Security, 2023
WARP, an efficient lightweight block cipher presented by Banik et al., offers a viable alternative to AES with its 128-bit block and a 128-bit key.

Between‐year and spatial variation in body condition across the breeding cycle in a pelagic seabird, the Red‐billed Tropicbird

Ecology and Evolution, Volume 13, Issue 12, December 2023., 2023
Body condition in Red‐billed Tropicbirds (Phaethon aethereus) at St Helena, South Atlantic Ocean varied considerably between years, affected by multiple different factors at different stages of the breeding cycle, likely influenced by the Angola Benguela upwelling system. Variation in chick growth rates at two regions in the Atlantic are also examined.

Spatial Composition of the Diahaline Overturning Circulation in a Fjord–Type, Non–Tidal Estuarine System

Journal of Geophysical Research: Oceans, Volume 128, Issue 12, December 2023., 2023
Abstract In this study we present new insights into the overturning circulation in non‐tidal, fjord‐type estuarine systems associated with diahaline mixing. As a realistic example we analyze 2 years of numerical model results for the Baltic Sea, a brackish semi‐enclosed marginal sea, characterized by strong freshwater surplus.

Modeling Slope Microclimates in the Mars Planetary Climate Model

Journal of Geophysical Research: Planets, Volume 128, Issue 10, October 2023., 2023
Abstract A large number of surface features (e.g., frost, gullies, slope streaks, recurring slope lineae) are observed on Martian slopes. Their activity is often associated with the specific microclimates on these slopes, which have been mostly studied with one‐dimensional radiative balance models to date. We develop here a parameterization to simulate

Towards Minimizing Non-linearity in Type-II Generalized Feistel Networks [PDF]

, 2023
Recent works have revisited blockcipher structures to achieve MPC- and ZKP-friendly designs. In particular, Albrecht et al. (EUROCRYPT 2015) first pioneered using a novel structure SP networks with partial non-linear layers (P-SPNs) and then (ESORICS ...

Implementation and Evaluation of a Machine Learned Mesoscale Eddy Parameterization Into a Numerical Ocean Circulation Model

Journal of Advances in Modeling Earth Systems, Volume 15, Issue 10, October 2023., 2023
Abstract We address the question of how to use a machine learned (ML) parameterization in a general circulation model (GCM), and assess its performance both computationally and physically. We take one particular ML parameterization (Guillaumin & Zanna, 2021, https://doi.org/10.1002/essoar.10506419.1) and evaluate the online performance in a different ...

Occurrence and conversion of progestogens and androgens are conserved in land plants

New Phytologist, Volume 240, Issue 1, Page 318-337, October 2023., 2023
Summary Progestogens and androgens have been found in many plants, but little is known about their biosynthesis and the evolution of steroidogenesis in these organisms. Here, we show that the occurrence and biosynthesis of progestogens and androgens are conserved across the viridiplantae lineage.

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

, 2014
通过对代数次数增加情况的分析,研究了type-1广义Feistel结构下,单SP(sub stitution-permutation)模型与双SP模型抵抗高阶差分分析的能力.结合高阶积分与高阶差分思想,开发了四路type-1广义Feistel-SP与Feistel-SPSP结构代数次数上界估计的新方法.利用这一方法,分别构造了这2种结构在2种常用参数下的区分器.结果显示,四路type-1广义Feistel结构下,双SP模型抵抗高阶差分攻击的能力不如单SP模型.The powers against the
