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.

Security Analysis of SKINNY under Related-Tweakey Settings
IACR Transactions on Symmetric Cryptology, 2017 In CRYPTO’16, a new family of tweakable lightweight block ciphers - SKINNY was introduced. Denoting the variants of SKINNY as SKINNY-n-t, where n represents the block size and t represents the tweakey length, the design specifies t ∈ {n, 2n, 3n}. In this

New Related-Tweakey Boomerang and Rectangle Attacks on Deoxys-BC Including BDT Effect
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 ...

Cryptanalysis of Reduced round SKINNY Block Cipher [PDF]
IACR Transactions on Symmetric Cryptology, 2018 SKINNY is a family of lightweight tweakable block ciphers designed to have the smallest hardware footprint. In this paper, we present zero-correlation linear approximations and the related-tweakey impossible differential characteristics for different ...

Single Tweakey Cryptanalysis of Reduced-Round SKINNY-64 [PDF]
IACR Transactions on Symmetric Cryptology, 2020 In CRYPTO’16, a new family of tweakable lightweight block ciphers - SKINNY was introduced. Denoting the variants of SKINNY as SKINNY-n-t, where n represents the block size and t represents the tweakey length, the design specifies t ∈ {n, 2n, 3n}. In this work, we evaluate the security of SKINNY against differential cryptanalysis in the related-tweakey ...

On Large Tweaks in Tweakable Even-Mansour with Linear Tweak and Key Mixing
IACR Transactions on Symmetric Cryptology, 2023 In this paper, we provide the first analysis of the Iterated Tweakable Even-Mansour cipher with linear tweak and key (or tweakey) mixing, henceforth referred as TEML, for an arbitrary tweak(ey) size kn for all k ≥ 1, and arbitrary number of rounds r ≥ 2.

Tweaks and Keys for Block Ciphers: The TWEAKEY Framework [PDF]
International Conference on the Theory and Application of Cryptology and Information Security, 2014 We propose the TWEAKEY framework with goal to unify the design of tweakable block ciphers and of block ciphers resistant to related-key attacks. Our framework is simple, extends the key-alternating construction, and allows to build a primitive with arbitrary tweak and key sizes, given the public round permutation (for instance, the AES round ...

Differential Attacks on CRAFT Exploiting the Involutory S-boxes and Tweak Additions
IACR Transactions on Symmetric Cryptology, 2020 CRAFT is a lightweight tweakable block cipher proposed at FSE 2019, which allows countermeasures against Differential Fault Attacks to be integrated into the cipher at the algorithmic level with ease.
