Additionally it seems to be prudent to avoid too many zeroes in the key matrix, since they reduce diffusion. The disadvantage of Caesar cipher is that it is way too simple for the current times. Hill Cipher was among the first polygraphic cipher systems to be built on the practical system with more than three symbols or letters in one. Two principal methods are used in substitution ciphers to lessen the extent to which the structure of the plaintext survives in the ciphertext: One approach is to encrypt multiple letters of plaintext, and the other is to use multiple cipher alphabets.
