Annotation: The article contains the description of research undertaken to assess the block symmetric cipher Kuznyechic cryptographic stability in case of impossible differentials method attacks. The way to assess the simplified versions of Kuznyechic cryptographic stability in case of impossible differentials method attacks was used to get the results. The results obtained were generalized for the full version of the cipher Kuznyechic.
Keywords: cipher Kuznyechik, cryptographic stability, impossible differentials, crypto-analysis, GOST R 34.12-2018
