Low-Complexity Key Recovery Attacks on GOST Block Cipher

Abstract

GOST is a well-known Russian government block cipher. Until 2010, there was no attack on GOST used in encryption, cf. [9]. More recently, quite a few distinct key recovery attacks on full GOST have been found: [1–4, 6, 7]. Most of these attacks work by so-called ‘‘complexity reduction’’ [1]; they reduce the problem of breaking the full 32-round GOST to an… (More)
