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 ...

A Note on Related-Tweakey Impossible Differential Attacks
IACR Communications in CryptologyIn this note we review the technique proposed at ToSC 2018 by Sadeghi et al. for attacks built upon several related-tweakey impossible differential trails. We show that the initial encryption queries are improper and lead the authors to misevaluate a filtering value in the key recovery phase.

Clustering Related-Tweak Characteristics: Application to MANTIS-6
IACR Transactions on Symmetric Cryptology, 2018 The TWEAKEY/STK construction is an increasingly popular approach for designing tweakable block ciphers that notably uses a linear tweakey schedule. Several recent attacks have analyzed the implications of this approach for differential cryptanalysis and ...

MILP-Aided Related-Tweak/Key Impossible Differential Attack and its Applications to QARMA, Joltik-BC
IEEE Access, 2019 In this paper, we study the relation of related-tweak/key impossible differentials with single-key ones. Following a heuristic strategy, we can derive longer related-tweak/key impossible differentials from single-key ones. We implement this strategy with

Cryptanalysis of Reduced round SKINNY Block Cipher
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 ...

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.

Analysis of AES, SKINNY, and Others with Constraint Programming
IACR Transactions on Symmetric Cryptology, 2017 Search for different types of distinguishers are common tasks in symmetrickey cryptanalysis. In this work, we employ the constraint programming (CP) technique to tackle such problems.

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
