Abstract: In this paper we consider a bit-sliced implementation of the non-linear transformation shared by GOST R 34.12-2015 “Kuznyechik” block cipher and GOST R 34.11-2012 “Streebog” hash function. We combine analytical and computer methods to get a 226 Boolean operations representation.

Key words: block cipher, hash function, S-box, Kuznyechik, Streebog, bit-slice, Boolean functions minimization.
