Abstract: For Markov block ciphers, the lumped states of Markov chains based on some partitions of the plaintexts set are considered. It is proved that such lumped states of a Markov chain generated by a sequence of intermediate ciphertexts of the Markov cipher are also a Markov chain.
Keywords: Markov cipher, Markov chain, XSL block cipher, Feistel block cipher.
