Inverting Cryptographic Hash Functions via Cube-and-Conquer

no code implementations5 Dec 2022 Oleg Zaikin

In this study, 40-, 41-, 42-, and 43-step MD4 are inverted for the first time via the first algorithm and the estimating mode of the second algorithm.

On Cryptographic Attacks Using Backdoors for SAT

no code implementations13 Mar 2018 Alexander Semenov, Oleg Zaikin, Ilya Otpuschennikov, Stepan Kochemazov, Alexey Ignatiev

Propositional satisfiability (SAT) is at the nucleus of state-of-the-art approaches to a variety of computationally hard problems, one of which is cryptanalysis.

Encoding Cryptographic Functions to SAT Using Transalg System

1 code implementation4 Jul 2016 Ilya Otpuschennikov, Alexander Semenov, Irina Gribanova, Oleg Zaikin, Stepan Kochemazov

We implemented this technology in the form of the software system called Transalg, and used it to construct SAT encodings for a number of cryptanalysis problems.
