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.

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 ...

Improved Related-Tweakey Boomerang Attacks on Deoxys-BC

Lecture Notes in Computer Science, 2018
This paper improves previous distinguishers and key recovery attacks against Deoxys-BC that is a core primitive of the authenticated encryption scheme Deoxys, which is one of the remaining candidates in CAESAR. We observe that previous attacks by Cid et al. published from ToSC 2017 have a lot of room to be improved.

Related-tweakey impossible differential attack on reduced-round Deoxys-BC-256

Science China Information Sciences, 2019
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 distinguisher of Deoxys-BC-256, which is transformed from a 3.5-round single-key impossible distinguisher of ...
