The approach to the formation of block scheduling keys for symmetric cryptographic algorithm GOST 28147-89

Y.N. Astashkina, I.V. Lysenko
Annotations languages:

In order to increase cryptographic proofness of the cryptographic algorithm GOST 28147-89 an approach to the formation of keys schedule for this algorithm is proposed. Two models of the keys schedule formation are considered relatively this approach.
Keywords: confidentiality, keys schedule, block cipher
