Abstract GOST 28147-89 is a well-known block cipher. Its large key size of 256 bits and
incredibly low implementation cost make it a plausible alternative for AES-256 and triple …

Abstract GOST 28147-89 is a well-known Russian government encryption standard. Its large
key size of 256 bits at a particularly low implementation cost make that it is widely …

GOST is a well-known Russian government standard block cipher which was submitted to
ISO in 2010 to become an international standard. A number of advanced differential attacks …

In this thesis, we study how to enhance current cryptanalytic techniques, especially in
Differential Cryptanalysis (DC) and to some degree in Algebraic Cryptanalysis (AC), by …

In this article the author revisits the oldest attack on GOST known, the Kara Reflection attack,
and another totally unrelated truncated differential attack by Courtois and Misztal. It is hard to …

Abstract Mazkur maqolada O 'zDSt 1105: 2009 algoritmida ishlatilgan akslantirishlarning
algebraik xususiyatlari tahlil qilinadi. Tadqiqotda algebraik kriptotahlil usuli asosida O 'zDSt …

Abstract GOST 28147-89 is a well-known block cipher and the official encryption standard of
the Russian Federation. A 256-bit block cipher considered as an alternative for AES-256 …

A matrix representation and upper bounds on the imbalance of an arbitrary discrete function
implemented by a sequence of finite automata are obtained. The obtained results generalize …

A new method is proposed to find the average probabilities of differential characteristics of
block ciphers, which allows us to use branch number even in case where the cipher is not …
