On the Feistel Counterpart of the Boomerang Connectivity Table
IACR Transactions on Symmetric Cryptology, 2020 At Eurocrypt 2018, Cid et al. introduced the Boomerang Connectivity Table (BCT), a tool to compute the probability of the middle round of a boomerang distinguisher from the description of the cipher’s Sbox(es). Their new table and the following works led

Dianzi Jishu Yingyong, 2021 NBC is a family of block ciphers using Generalized Feistel structure, designed by Xu Hong et al. There are three block and key sizes,i.e.,128/128, 128/256 and 256/256. A 16-bit Sbox is involved in the cipher as the non-linear component.

A Modified Feistel Cipher Involving XOR Operation and Modular Arithmetic Inverse of a Key Matrix
, 2012 In this paper, we have developed a block cipher by modifying the Feistel cipher. In this, the plaintext is taken in the form of a pair of matrices. In one of the relations of encryption the plaintext is multiplied with the key matrix on both the sides ...

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.

Responses of Reef Fish Populations to Similar Environmental Changes Across Distant Oceanic Islands
Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 4, April 2026.ABSTRACT Oceanic islands are among the most remote and understudied regions of the planet, yet they harbour unique reef fish communities that are increasingly vulnerable to global environmental change. Because these islands are geographically isolated, their populations are often assumed to respond mainly to local environmental conditions.

A Novel Feistel Cipher Involving a Bunch of Keys Supplemented with XOR Operation
, 2012 In this investigation, we have developed a novel block cipher by modifying classical Feistel cipher. In this, we have used a key bunched wherein each key has a multiplicative inverse. The cryptanalysis carried out in this investigation clearly shows that

Eddy‐Induced Iron Transport Sustains the Biological Productivity in the Gulf of Alaska
Journal of Geophysical Research: Oceans, Volume 131, Issue 2, February 2026.Abstract The surface waters of the subarctic northeastern Pacific Ocean contain high concentrations of macronutrients such as phosphate and nitrate, which can potentially drive photosynthesis and biological uptake of carbon dioxide. Regional biological productivity, however, is limited by a lack of necessary micronutrients such as iron.

Unbalanced Feistel networks and block cipher design [PDF]
, 1996 We examine a generalization of the concept of Feistel networks, which we call Unbalanced Feistel Networks (UFNs). Like conventional Feistel networks, UFNs consist of a series of rounds in which one part of the block operates on the rest of the block. However, in a UFN the two parts need not be of equal size. Removing this limitation on Feistel networks

A Novel Feistel Cipher Involving a Bunch of Keys supplemented with Modular Arithmetic Addition
, 2012 In the present investigation, we developed a novel Feistel cipher by dividing the plaintext into a pair of matrices. In the process of encryption, we have used a bunch of keys and modular arithmetic addition. The avalanche effect shows that the cipher is

Differential Attacks by Algebraic Solving on a Series of HE‐Friendly Stream Ciphers
IET Information Security, Volume 2026, Issue 1, 2026.In recent years, many symmetric encryption ciphers have been proposed for homomorphic encryption (HE) applications. Rasta and its variants Masta and Pasta have gradually become a self‐contained series of HE‐friendly stream ciphers. The feature of these ciphers is that a fresh affine layer is randomly generated for each encryption.
