Differential properties of the S-boxes of GOST 28147-89 algorithm

Abstract

Differential properties of the S-boxes of GOST 28147-89 algorithm

Ischukova E.A., Kalmykov I.A.

Incoming article date: 02.10.2015

The paper presents the basic differential characteristics identified for the S-boxes of GOST 28147-89 algorithm, included in the data encryption standard GOST 34.12-2015, which comes into force from January 1, 2016. The detected properties can be used for analysis with such methods as differential cryptanalysis and impossible differential cryptanalysis.

Keywords: encryption algorithm, symmetric encryption, block cipher, S-boxes, differential cryptanalysis, impossible differential cryptanalysis, differential properties
