The Luby — Rackoff scheme is a Markov cipher. The eighth power of the matrix of transition probabilities of differentials of the Lyubi — Rakoff scheme is calculated, estimates of the volume of material for a $j$-vector ($j=1,2$) discriminative attack are given for an $8$-round scheme in the model of independent two-block texts.
Keywords: Markov block ciphers, Luby — Rackoff scheme, distinguishing attack, transition probabilities of differentials.
