Cellular automata were originally proposed by researcher as formal models of self reproducing organisms. The structure studied was most on one and two-dimensional infinite grids, through higher dimensions were considered. Cellular automata are widely of applications like in cryptography, computer graphics, neural network etc. Cryptography is an important and vital application in security, defense, medical, business and many other application areas. The effective measure of a crypto system is how long it can be used to encrypt and decrypt messages without the 'Key' being broken.
