Automated Search Oriented to Key Recovery on Ciphers with Linear Key Schedule
IACR Transactions on Symmetric Cryptology, 2021 Automatic modelling to search distinguishers with high probability covering as many rounds as possible, such as MILP, SAT/SMT, CP models, has become a very popular cryptanalysis topic today.

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 ...

Accelerating the Search of Differential and Linear Characteristics with the SAT Method
IACR Transactions on Symmetric Cryptology, 2021 The introduction of the automatic search boosts the cryptanalysis of symmetric-key primitives to some degree. However, the performance of the automatic search is not always satisfactory for the search of long trails or ciphers with large state sizes ...

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 ...

On Boomerang Attacks on Quadratic Feistel Ciphers
IACR Transactions on Symmetric Cryptology, 2023 The recent introduction of the Boomerang Connectivity Table (BCT) at Eurocrypt 2018 revived interest in boomerang cryptanalysis and in the need to correctly build boomerang distinguishers.

Exploring Differential-Based Distinguishers and Forgeries for ASCON
IACR Transactions on Symmetric Cryptology, 2021 Automated methods have become crucial components when searching for distinguishers against symmetric-key cryptographic primitives. While MILP and SAT solvers are among the most popular tools to model ciphers and perform cryptanalysis, other methods with ...

Analysis of added mass in cavitating flow [PDF]
, 2012 The paper addresses a theoretical study of the added mass effect in cavitating flow.The cavitation is considered to induce a strong time–space variation of the fluid density at the interface between an inviscid fluid and a three-degree-of-freedom rigid ...
