Exact maximum expected differential and linear probability for 2-round Kuznyechik

Vitaly Kiryukhin

Abstract

This paper presents the complete description of the best differentials and linear hulls in 2-round Kuznyechik. We proved that 2-round $\mathrm{MEDP}=2^{-86.66...}$, $\mathrm{MELP}=2^{-76.739...}$. A comparison is made with similar results for the AES cipher.
