Block cipher with improved dynamic indicators of the condition of a random substitution
Konstantin Lisickiy, Viktor Dolgov, Iryna Lisickaya · 2017
On the example of the improved cipher of Kalina-2, SPN ciphers with improved indicators of their transition to the state of random substitution is offering. The improvement is basing on the application of the first cycle transformation of the new design, which allows activating all S-blocks of the second cycle. Ciphers are not inferior to the speed of known structures and allow without reducing the stability to use in them random S-blocks.
