New Related-Tweakey Boomerang and Rectangle Attacks on Deoxys-BC Including BDT Effect [PDF]
IACR Transactions on Symmetric Cryptology, 2019 In the CAESAR competition, Deoxys-I and Deoxys-II are two important authenticated encryption schemes submitted by Jean et al. Recently, Deoxys-II together with Ascon, ACORN, AEGIS-128, OCB and COLM have been selected as the final CAESAR portfolio ...

Impossible Boomerang Attacks Revisited
IACR Transactions on Symmetric CryptologyThe 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. In

Improved Meet-in-the-Middle Attacks on Reduced-Round Tweakable Block Cipher Deoxys-BC
The Computer Journal, 2021 Abstract Deoxys-BC is an internal tweakable block cipher of the authenticated encryption algorithm Deoxys, which is a third-round finalist in the CAESAR competition. In this paper, we study the property of Deoxys-BC, such as the subtweakey difference cancelation and the freedom of the tweak.

A Security Analysis of Deoxys and its Internal Tweakable Block Ciphers
IACR Transactions on Symmetric Cryptology, 2017 In this article, we provide the first independent security analysis of Deoxys, a third-round authenticated encryption candidate of the CAESAR competition, and its internal tweakable block ciphers Deoxys-BC-256 and Deoxys-BC-384.

Meet‐in‐the‐middle attacks on round‐reduced tweakable block cipher Deoxys‐BC
IET Information Security, 2019 Deoxys‐BC is a tweakable block cipher designed by Jean et al . at ASIACRYPT 2014 within the TWEAKEY framework. Then Deoxys‐BC is used in the CAESAR finalist Deoxys. In this study, the authors consider the security of Deoxys‐BC against meet‐in‐the‐middle attack in the single‐key setting. Using
