The QARMAv2 Family of Tweakable Block Ciphers

IACR Transactions on Symmetric Cryptology, 2023
We introduce the QARMAv2 family of tweakable block ciphers. It is a redesign of QARMA (from FSE 2017) to improve its security bounds and allow for longer tweaks, while keeping similar latency and area.

Boomerang Connectivity Table:A New Cryptanalysis Tool [PDF]

, 2018
A boomerang attack is a cryptanalysis framework that regards a block cipher $E$ as the composition of two sub-ciphers $E_1\circ E_0$ and builds a particular characteristic for $E$ with probability $p^2q^2$ by combining differential characteristics for ...

Differential Cryptanalysis of Round-Reduced Sparx-64/128 [PDF]

, 2018
Sparx is a family of ARX-based block ciphers designed according to the long-trail strategy (LTS) that were both introduced by Dinu et al. at ASIACRYPT'16.

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

Quantum Boomerang Attacks and Some Applications

, 2022
In this paper, we study quantum key-recovery attacks on block ciphers. While it is well known that a quantum adversary can generically speed up an exhaustive search of the key, much less is known on how to use specific vulnerabilities of the cipher to accelerate this procedure.

On the Boomerang Uniformity of Cryptographic Sboxes

IACR Transactions on Symmetric Cryptology, 2018
The boomerang attack is a cryptanalysis technique against block ciphers which combines two differentials for the upper part and the lower part of the cipher.

Related-Key Boomerang and Rectangle Attacks [PDF]

, 2005
The boomerang attack and the rectangle attack are two attacks that utilize differential cryptanalysis in a larger construction. Both attacks treat the cipher as a cascade of two sub-ciphers, where there exists a good differential for each sub-cipher, but not for the entire cipher.

Hannah Arendt's Ghosts:Reflections on the Disputable Path from Windhoek to Auschwitz [PDF]

, 2009
Historians on both sides of the Atlantic are currently engaged in a controversy about the allegedly genocidal nature of western colonialism and its connections with the mass violence unleashed by Nazi Germany between 1939 and 1945.

Cultural Revolution: Mykhail Semenko, Ukrainian Futurism and the “National” Category [PDF]

, 2017
This paper examines Mykhail Semenko’s Futurist manifestos that developed an opposition between “national” and “international” art, and specifically called “national” art provincial and retrograde.
