Abstract:
A group generated by the set of the round functions is often used to describe properties of a block cipher. The results obtained by A. S. Maslov in 2007 are used to prove that round functions of Kuznyechik and Stribog generate the alternating groups. We prove a theorem on the mixing properties of linear transformations and apply this theorem to the family of Stribog-like ciphers (Stribog, Anubis, etc.).
Key words:
GOST R 34.11–2012, GOST R 34.12–2015, Kuznyechik, Stribog, permutation groups, alternating group, linear transformation of block cipher.
