IACR Transactions on Symmetric Cryptology, 2021 This work investigates a generic way of combining two very effective and well-studied cryptanalytic tools, proposed almost 18 years apart, namely the boomerang attack introduced by Wagner in FSE 1999 and the yoyo attack by Ronjom et al. in Asiacrypt 2017.

Throwing Boomerangs into Feistel Structures
IACR Transactions on Symmetric Cryptology, 2022 Automatic tools to search for boomerang distinguishers have seen significant advances over the past few years. However, most previous work has focused on ciphers based on a Substitution Permutation Network (SPN), while analyzing the Feistel structure is

Improved Rectangle Attacks on SKINNY and CRAFT
IACR Transactions on Symmetric Cryptology, 2021 The boomerang and rectangle attacks are adaptions of differential cryptanalysis that regard the target cipher E as a composition of two sub-ciphers, i.e., E = E1 ∘ E0, to construct a distinguisher for E with probability p2q2 by concatenating two short ...

Boomerang Attacks on BLAKE-32 [PDF]
, 2011 We present high probability differential trails on 2 and 3 rounds of BLAKE-32. Using the trails we are able to launch boomerang attacks on up to 8 round-reduced keyed permutation of BLAKE-32. Also, we show that boomerangs can be used as distinguishers for hash/ compression functions and present such distinguishers for the compression function of BLAKE ...

Boomerang Switch in Multiple Rounds. Application to AES Variants and Deoxys
IACR Transactions on Symmetric Cryptology, 2019 The boomerang attack is a cryptanalysis technique that allows an attacker to concatenate two short differential characteristics. Several research results (ladder switch, S-box switch, sandwich attack, Boomerang Connectivity Table (BCT), ...) showed that ...

New Properties of the Double Boomerang Connectivity Table
IACR Transactions on Symmetric Cryptology, 2022 The double boomerang connectivity table (DBCT) is a new table proposed recently to capture the behavior of two consecutive S-boxes in boomerang attacks.

The QARMAv2 Family of Tweakable Block Ciphers
IACR Transactions on Symmetric Cryptology, 2023 We introduce the QARMAv2 family of tweakable block ciphers. It is a redesign of QARMA (from FSE 2017) to improve its security bounds and allow for longer tweaks, while keeping similar latency and area.

Boomerangs of Academic Freedom
Workplace, 2013 The Ted Steele case is an important episode in the defense of academic freedom in Australia. In addition, it offers a wealth of evidence on how a dismissal, perceived as an attack on academic freedom and free speech, can boomerang on the administration ...
