On probabilities of r-round differences of a markov xsl block cipher with a reducible linear transformation

Round functions in XSL block ciphers consist of three layers. The first is a key addition layer; the second is a nonlinear s-box layer; the third is a linear layer. Here, for a Markov XSL block cipher with a reducible linear transformation, instead of "classical" r-round differential characteristic used in differential technique, a r-round differential characteristic defined by the sequence of invariant subspace cosets of the linear transformation is considered.
