The paper presents results of implementation and investigation of cryptographic hash functions on the basis of cellular automata processing rules. The developed permutation functions possess satisfactory scattering properties and enable one to generate variable-length message digest. Improvement of statistical characteristics and avalanche effect has been achieved for processing functions, which combine several transformation rules of cellular automata with bitwise operations of cyclic shift and XOR.
Keywords: cryptographic hash functions, cellular automata, cryptographic sponge, Keccak algorithm
