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 ...

Improved related‐tweakey rectangle attacks on round‐reduced Deoxys‐BC
IET Information Security, 2023 Deoxys‐BC is the internal tweakable block cipher of the authenticated encryption (AE) Deoxys family, in which Deoxys‐II is the primary choice for the use case of ‘Defence in depth’ among the portfolio of CAESAR competition.

Impossible Differential Cryptanalysis of 8-Round Deoxys-BC-256
IEEE Access, 2018 Deoxys is a third-round candidate of the CAESAR authenticated encryption competition. In this paper, we present the first cryptanalysis of Deoxys in the single-key model.

Impossible Differential Cryptanalysis on Deoxys-BC-256 [PDF]
, 2018 Deoxys is a final-round candidate of the CAESAR competition. Deoxys is built upon an internal tweakable block cipher Deoxys-BC, where in addition to the plaintext and key, it takes an extra non-secret input called a tweak. This paper presents the first impossible differential cryptanalysis of Deoxys-BC-256 which is used in Deoxys as an internal ...

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

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

Impossible Differential Cryptanalysis of Reduced-Round Tweakable TWINE [PDF]
Progress in Cryptology - AFRICACRYPT 202012th International Conference on Cryptology in Africa, 2020 Tweakable TWINE (T-TWINE) is a new lightweight tweakable block cipher family proposed by Sakamoto $et$ $al$. at IWSEC 2019. T-TWINE is the first Tweakable Block Cipher (TBC) that is built on Generalized Feistel Structure (GFS).

Truncated Boomerang Attacks and Application to AES-Based Ciphers [PDF]
Lecture Notes in Computer Science, 2023 The boomerang attack is a cryptanalysis technique that combines two short differentials instead of using a single long differential. It has been applied to many primitives, and results in the best known attacks against several AES-based ciphers (Kiasu-BC,
