This stream of cryptography is completely based on the ideas of mathematics such as number theory and computational complexity theory, as well as concepts of probability. Lookup the, one approach to improving security was to encrypt, invented by Charles Wheatstone in 1854, but named, a 5X5 matrix of letters based on a keyword, fill in letters of keyword (filter duplicates), plaintext is encrypted two letters at a time, if a pair is a repeated letter, insert filler, if both letters fall in the same row, replace, if both letters fall in the same column, replace, otherwise each letter is replaced by the letter, Security much improved over monoalphabetic, Since still has much of plaintext structure.
