A cellular automaton-based cryptogram is developed. An alternative approach that combines theories from the Wolfram automata, the cellular automata transforms and reversible cellular automata. is presented. The approach is particularly applicable to session cryptography. It is designed so as to be implemented over simple computer systems and one-to-one data transmission channels. An illustrative example is given for verification.
