This paper introduces a Cellular Automata (CA) based symmetric key cryptosystem for block cipher. The scheme named as CAC (Cellular Automata based Cryptosystem) employs a series of transforms – simple, moderately complex, and complex – all generated with different classes of CA. CAC provides a low cost, high speed cryptosystem with desired level of security. Cryptanalysis of the proposed scheme is reported along with similar analysis for two popular systems DES and AES. Experimental results… CONTINUE READING
