Improved related‐tweakey rectangle attacks on round‐reduced Deoxys‐BC [PDF]
IET Information Security, 2022 Abstract 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.

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. Notably, Deoxys-II is also the primary choice for the use case “Defense in depth”.

Security Analysis of SKINNY under Related-Tweakey Settings (Long Paper)
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 work, we evaluate the security of SKINNY against differential cryptanalysis in the related-tweakey ...

A Note on Related-Tweakey Impossible Differential Attacks [PDF]
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.

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

Nonce‐misuse resilience of Romulus‐N and GIFT‐COFB
IET Information Security, Volume 17, Issue 3, Page 468-484, May 2023., 2023 Abstract Nonce‐misuse resilience (NMRL) security of Romulus‐N and GIFT‐COFB is analysed, the two finalists of NIST Lightweight Cryptography project for standardising lightweight authenticated encryption. NMRL, introduced by Ashur et al. at CRYPTO 2017, is a relaxed security notion from a stronger, nonce‐misuse resistance notion. The authors have proved

Meet‐in‐the‐middle attacks on round‐reduced CRAFT based on automatic search
IET Information Security, Volume 17, Issue 3, Page 534-543, May 2023., 2023 We construct a DS‐MITM automatic search model for CRAFT and use the automatic search model to detect a 9‐round DS‐MITM distinguisher. Based on the 9‐round distinguisher, 19/20‐round DS‐MITM attacks can be presented. Abstract CRAFT is a lightweight block cipher designed by Beierle et al.

Chinese Journal of Electronics, Volume 31, Issue 4, Page 698-712, July 2022., 2022 Many cryptanalytic techniques for symmetric‐key primitives rely on specific statistical analysis to extract some secrete key information from a large number of known or chosen plaintext‐ciphertext pairs. For example, there is a standard statistical model for differential cryptanalysis that determines the success probability and complexity of the attack
