In EUROCRYPT 2018, Cid et al. introduced a new concept on the cryptographic property of S-boxes: Boomerang Connectivity Table (BCT for short) for evaluating the subtleties of boomerang-style attacks. ...
Recently, the Boomerang Connection Table was introduced by Cid et al.~as a tool to better evaluate the probability of a boomerang distinguisher. To compute the BCT of an nn-bit to nn-bit S-box, the in...
With the BCT, previous observations on the S-box including the incompatibility, the ladder switch and the S-box switch are represented in a unified manner. Moreover, the BCT can detect a new switching...
Impossible-Differential and Boomerang Cryptanalysis of Round-Reduced Kiasu-BC
cryptanalysis tweakable block cipher
2016/12/29
Kiasu-BC is a tweakable block cipher proposed by Jean et al. at ASIACRYPT 2014 alongside their TWEAKEY framework. The cipher is almost identical to the AES-128 except for the tweak, which renders it a...
Analysis of Boomerang Differential Trails via a SAT-Based Constraint Solver URSA
Boomerang Differential Trails SAT-Based Constraint Solver URSA
2016/1/8
In order to obtain differential patterns over many rounds of a cryptographic primitive,
the cryptanalyst often needs to work on local differential trail analysis. Examples include
merging two differ...
SHA-2 (SHA-224, SHA-256, SHA-384 and SHA-512) is hash
function family issued by the National Institute of Standards and Technology
(NIST) in 2002 and is widely used all over the world. In this work,...
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 c...

The MMB block cipher (Modular Multiplication-based Block cipher) is an iterative block cipher designed by Daemen, Govaerts, and Vandewalle in 1993 as an improvement of the PES and IPES ciphers.
In th...
