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.

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

Clustering Related-Tweak Characteristics: Application to MANTIS-6 [PDF]
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 ...

Cryptanalysis of Forkciphers [PDF]
IACR Transactions on Symmetric Cryptology, 2020 The forkcipher framework was designed in 2018 by Andreeva et al. for authenticated encryption of short messages. Two dedicated ciphers were proposed in this framework: ForkAES based on the AES (and its tweakable variant Kiasu-BC), and ForkSkinny based on

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

Efficient constructions for large‐state block ciphers based on AES New Instructions
IET Information Security, Volume 16, Issue 3, Page 145-160, May 2022., 2022 Abstract Large‐state block ciphers with 256 bits or 512 bits block sizes receive much attention from the viewpoint of long‐term security. Existing large‐state block ciphers, such as Haraka‐v2 and Pholkos, consist of only the AES New Instructions set (AES‐NI) and a word shuffle that can be efficiently executed by SIMD instructions for fast software ...

Multiple Impossible Differential Attacks for ForkAES
Security and Communication Networks, Volume 2022, Issue 1, 2022., 2022 To yield a highly efficient authentication encryption design for very short messages, the tweakable forkcipher is proposed, which is a tweakable block cipher that uses forking construction to produce two output blocks. The designers also presented ForkAES, a forkcipher that is based on the round function of AES and the tweakable variant of KIASU ...

Improved meet‐in‐the‐middle attacks on reduced‐round Joltik‐BC
IET Information Security, Volume 15, Issue 3, Page 247-255, May 2021., 2021 Abstract Joltik‐BC is an internal tweakable block cipher of the authenticated encryption algorithm Joltik, which was a second‐round finalist in the CAESAR competition. The authors study the key‐recovery attacks on Joltik‐BC under meet‐in‐the‐middle attack.
