WebPlayfair encryption uses a grid, which can be generated by a key word. Split the text into bigrams of 2 letters (complete with a letter if the message is of odd length). Apply the … Polygraphic substitution is a cipher in which a uniform substitution is performed on blocks of letters. When the length of the block is specifically known, more precise terms are used: for instance, a cipher in which pairs of letters are substituted is bigraphic. As a concept, polygraphic substitution contrasts with … See more In 1563, Giambattista della Porta devised the first bigraphic substitution. However, it was nothing more than a matrix of symbols. In practice, it would have been all but impossible to memorize, and carrying around the table … See more • Topics in cryptography See more Polygraphic systems do provide a significant improvement in security over monoalphabetic substitutions. Given an individual letter 'E' in a message, it could be encrypted using any of 52 instructions depending on its location and neighbors, which can be used … See more

WebIn polyalphabetic substitution ciphers one should define a few possible combinations of substitutions of all alphabet letters by other letters. Then, one should use the substitutions cyclically, one after the other, changing the replacement after each new letter.
