Impossible Boomerang Attacks Revisited: Applications to Deoxys-BC, Joltik-BC and SKINNY [PDF]
The 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.

A Holistic Framework for Impossible Boomerang Attacks [PDF]
In 2011, Lu introduced the impossible boomerang attack at DCC. This powerful cryptanalysis technique combines the strengths of the impossible differential and boomerang attacks, thereby inheriting the advantages of both cryptographic techniques.

Related-Tweakey Impossible Differential Attack on Reduced-Round Deoxys-BC-256 [PDF]
, 2018 Deoxys-BC is the internal tweakable block cipher of Deoxys, a third-round authenticated encryption candidate at the CAESAR competition. In this study, by adequately studying the tweakey schedule, we seek a six-round related-tweakey impossible ...

Chosen-Key Distinguishing Attacks on Full AES-192, AES-256, Kiasu-BC, and More [PDF]
, 2023 At CRYPTO 2020, Liu et al. find that many differentials on Gimli are actually incompatible. On the related-key differential of AES, the incompatibilities also exist and are handled in different ad-hoc ways by adding respective constraints into the ...

Boomerang Connectivity Table Revisited. Application to SKINNY and AES [PDF]
, 2019 The boomerang attack is a variant of differential cryptanalysis which regards a block cipher E as the composition of two sub-ciphers, i.e., E = E1 o E0, and which constructs distinguishers for E with probability p2q2 by combining differential trails for ...

Truncated Boomerang Attacks and Application to AES-based Ciphers [PDF]
, 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,

Key-Recovery Attacks on CRAFT and WARP (Full Version) [PDF]
, 2022 This paper considers the security of CRAFT and WARP. We present a practical key-recovery attack on full-round CRAFT in the related-key setting with only one differential characteristic, and the theoretical time complexity of the attack is $2^{36.09 ...
