On the Feistel Counterpart of the Boomerang Connectivity Table

open access: yesIACR Transactions on Symmetric Cryptology, 2020
At Eurocrypt 2018, Cid et al. introduced the Boomerang Connectivity Table (BCT), a tool to compute the probability of the middle round of a boomerang distinguisher from the description of the cipher’s Sbox(es). Their new table and the following works led

Hash Functions and the (Amplified) Boomerang Attack [PDF]

open access: yes, 2007
Since Crypto 2004, hash functions have been the target of many attacks which showed that several well-known functions such as SHA-0 or MD5 can no longer be considered secure collision free hash functions. These attacks use classical cryptographic techniques from block cipher analysis such as differential cryptanalysis together with some specific ...

The Boomerang Attack [PDF]

open access: yes, 1999
This paper describes a new differential-style attack, which we call the boomerang attack. This attack has several interesting applications. First, we disprove the of t-repeated claim that eliminating all high-probability differentials for the whole cipher is sufficient to guarantee security against differential attacks.

Related-Key Boomerang and Rectangle Attacks [PDF]

open access: yes, 2005
The boomerang attack and the rectangle attack are two attacks that utilize differential cryptanalysis in a larger construction. Both attacks treat the cipher as a cascade of two sub-ciphers, where there exists a good differential for each sub-cipher, but not for the entire cipher.

Differential Cryptanalysis and Boomerang Cryptanalysis of LBlock [PDF]

open access: yes, 2013
Part 1: Modern CryptographyInternational audienceLBlock is a lightweight block cipher proposed in ACNS 2011. It has a 64-bit block size and 80-bit key size which is the typical parameter setting accepted by most of the recent proposed lightweight block ...

A tutorial of boomerang attack on SMALLPRESENT-[4]

open access: yesJournal of Physics: Conference Series, 2021
Abstract In 2010, Leander proposed a new version of the block cipher PRESENT with smaller block size, namely SMALLPRESENT-[n]. This algorithm is designed to deepen understanding of how the running time of the algorithm and the vulnerability of attack during the round increase with the number of rounds and s-boxes not determined on the ...

Revisiting the Boomerang Attack from a Perspective of 3-differential [PDF]

open access: yes, 2023
In this paper, inspired by the work of Beyne and Rijmen at CRYPTO 2022, we explore the accurate probability of $d$-differential in the fixed-key model.

The Boomerang Attacks on the Round-Reduced Skein-512 [PDF]

open access: yes, 2013
The hash function Skein is one of the five finalists of the NIST SHA-3 competition. It is based on the block cipher Threefish which only uses three primitive operations: modular addition, rotation and bitwise XOR (ARX). This paper studies the boomerang attacks on Skein-512.

New Related-Tweakey Boomerang and Rectangle Attacks on Deoxys-BC Including BDT Effect

open access: yesIACR 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 ...
