Abstract:
A model of iterated block ciphers with alphabet X, independent uniform round keys and a key addition group (X,⊗) is considered. We find conditions ensuring the preservation of Markov property under lumping of Markov chain with state space X2 corresponding to bigrams of intermediate ciphertexts. We describe properties of Markov ciphers considered and lumping transforms.
Key words:
Markov block cipher, Markov chain, states lumping, truncated differential technique.
