Improved Search for Integral, Impossible-Differential and Zero-Correlation Attacks: Application to Ascon, ForkSKINNY, SKINNY, MANTIS, PRESENT and QARMAv2 [PDF]

, 2023
Integral, impossible-differential (ID), and zero-correlation (ZC) attacks are three of the most important attacks on block ciphers. However, manually finding these attacks can be a daunting task, which is why automated methods are becoming increasingly ...

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 ...

Impossible Differential Cryptanalysis of Reduced-Round SKINNY [PDF]

, 2017
SKINNY is a new lightweight tweakable block cipher family proposed by Beierle $et$ $al$. in CRYPTO 2016. SKINNY-$n$-$t$ is a block cipher with $n$-bit state and $t$-bit tweakey (key and tweak).

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 ...

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 ...

Key-Recovery Attacks on CRAFT and WARP (Full Version) [PDF]

, 2022
This paper considers the security of CRAFT and WARP. We present a practical key-recovery attack on full-round CRAFT in the related-key setting with only one differential characteristic, and the theoretical time complexity of the attack is $2^{36.09 ...
