While brooms and sponges are the means of choice to fight contamination in everyday life, cleaning sensitive surfaces such as electronic components requires different tools, including evaporation-base...
In order to study the resistance of a block cipher against boomerang attacks, a tool called the Boomerang Connectivity Table (BCT) for S-boxes was recently introduced. Very little is known today about...

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...
ALMA returns to Boomerang Nebula:Companion star provides chilling power of 'Coldest Object in the Universe'
ALMA Boomerang Nebula Companion star chilling power Coldest Object in the Universe
2017/7/21
An ancient, red giant star in the throes of a frigid death has produced the coldest known object in the cosmos — the Boomerang Nebula. How this star was able to create an environment strikingly colder...
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...
