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

Authors: 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.
