In this paper, we introduce cellular automata and propose a new block cipher algorithm based on cellular automata. For the evaluation of performance and security, we compare the results of the proposed algorithm with them of the standard block ciphers such as DES, Rijndael regarding on avalanche effects and processing time, and analyze the differential cryptanalysis for a reduction version of the proposed algorithm. In addition, we perform the statistical tests in FIPS PUB 140-2(Federal Information Processing Standards Publication 140-2) for the output bit sequences of proposed algorithm to guarantee the randomness property.
