In this paper, the authors present a reversible cellular automata based one dimensional cryptographic algorithm. This algorithm use specially selected reversible rules which are cryptographically secure and faster to compute. The strength and quality of the algorithm depends upon the rules used and the randomness of number used in the process of encryption and decryption. This algorithm also implements CA based S-box which improves the performance over existing S-box used in Data Encryption Standard (DES) or in Advanced Encryption Standards (AES) .
