Cellular automaton cryptosystems

The new class of cryptosystems based on reversible cellular automatons is constructed. Full description of two examples of cellular automaton cryptosystems is given: namely cryptosystem based on cellular automaton with Moore neighbor and cryptosystem based on cellular automaton on partitioning. First type cryptosystem uses key for controlling over process of cellular automaton rule change by which every cell computes next state from his neighbors current states. Second type cryptosystem uses key for controlling over cellular automaton on portioning dynamics development, namely for controlling over following parameters: lattice block height, lattice block width, shift size in rule table and step number of cellular automaton development.
