In this paper, new results of the analysis of the KB 256-3 block cipher algorithm are outlined. We set up a difference relation with probability 1 for the six-round algorithm under study and propose a key recovery method using this difference relation for the nine-round KB 256-3 algorithm. We construct an impossible differential for the full-round algorithm.
Keywords: differential cryptanalysis, impossible differentials.
