The Retracing Boomerang Attack, with Application to Reduced-Round AES [PDF]
Journal of CryptologyAbstractBoomerang attacks are extensions of differential attacks that make it possible to combine two unrelated differential properties of the first and second part of a cryptosystem with probabilities p and q into a new differential-like property of the whole cryptosystem with probability $$p^2q^2$$

The Boomerang Attacks on BLAKE and BLAKE2 [PDF]
, 2015 In this paper, we study the security margins of hash functions BLAKE and BLAKE2 against the boomerang attack. We launch boomerang attacks on all four members of BLAKE and BLAKE2, and compare their complexities. We propose 8.5-round boomerang attacks on both BLAKE-512 and BLAKE2b with complexities \(2^{464}\) and \(2^{474}\) respectively.

Related-Key Boomerang Attack on Block Cipher SQUARE [PDF]
IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences, 2011 Square is an 8-round SPN structure block cipher and its round function and key schedule have been slightly modified to design building blocks of Rijndael. Key schedule of Square is simple and efficient but fully affine, so we apply a related-key attack on it.

A Formal Analysis of Boomerang Probabilities
IACR Transactions on Symmetric Cryptology, 2022 In the past 20 years since their conception, boomerang attacks have become an important tool in the cryptanalysis of block ciphers. In the classical estimate of their success probability, assumptions are made about the independence of the underlying ...

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 ...

Operation Pillar of Defence and the 2013 Israeli elections: defensive or provocative intervention? [PDF]
, 2014 Based on the research on the psychological and political effects of terrorism, this paper focuses on the possible use of provocative counter-terrorism operations in order to influence the outcome of elections.

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 ...
