Improved Related-Tweakey Rectangle Attacks on Reduced-round Deoxys-BC-384 and Deoxys-I-256-128 [PDF]

, 2020
Deoxys-BC is the core internal tweakable block cipher of the authenticated encryption schemes Deoxys-I and Deoxys-II. Deoxys-II is one of the six schemes in the final portfolio of the CAESAR competition, while Deoxys-I is a 3rd round candidate.

Related-Tweakey Impossible Differential Attack on Reduced-Round Deoxys-BC-256 [PDF]

, 2018
Deoxys-BC is the internal tweakable block cipher of Deoxys, a third-round authenticated encryption candidate at the CAESAR competition. In this study, by adequately studying the tweakey schedule, we seek a six-round related-tweakey impossible ...

Dialga: A Family of Low-Latency Tweakable Block Ciphers Using Multiple Linear Layers

IACR Transactions on Symmetric Cryptology
In this paper, we propose Dialga, a family of low-latency tweakable block ciphers designed to support 128/256-bit tweaks and 256-bit keys. Dialga achieves significantly small latency by leveraging multiple novel strategies.

Cryptanalysis of QARMAv2

IACR Transactions on Symmetric Cryptology
QARMAv2 is a general-purpose and hardware-oriented family of lightweight tweakable block ciphers (TBCs) introduced in ToSC 2023. QARMAv2, as a redesign of QARMAv1 with a longer tweak and tighter security margins, is also designed to be suitable for ...

Computing the Differential Probability of a Word-Based Block Cipher

Cryptography
Differential cryptanalysis is one of the fundamental cryptanalysis techniques to evaluate the security of the block cipher. In many cases, resistance to differential cryptanalysis is proven through the upper bound of the differential characteristic ...

Impossible Boomerang Attacks Revisited: Applications to Deoxys-BC, Joltik-BC and SKINNY [PDF]

The impossible boomerang (IB) attack was first introduced by Lu in his doctoral thesis and subsequently published at DCC in 2011. The IB attack is a variant of the impossible differential (ID) attack by incorporating the idea of the boomerang attack.
