A General Analysis of the Security of Elastic Block Ciphers [PDF]

open access: yes, 2005
We analyze the security of elastic block ciphers in general to show that an attack on an elastic version of block cipher implies a polynomial time related attack on the fixed-length version of the block cipher.

On the Feistel Counterpart of the Boomerang Connectivity Table

open access: yesIACR 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

Cryptanalysis of NBC-128

open access: yesDianzi 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.

Responses of Reef Fish Populations to Similar Environmental Changes Across Distant Oceanic Islands

open access: yesAquatic 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.
