WebA polyalphabetic cipher substitution, ... For this encipherment Alberti used a decoder device, his cipher disk, ... was a major advance—the most significant in the several hundred years since frequency analysis had been developed. A reasonable implementation would have been (and, when finally achieved, was) vastly harder to break. ... WebThere is a function from the first of every three characters in the plaintext to the first of every four characters in the Base64 encoding; we can perform a variant of single-letter frequency analysis on the ciphertext restricted to the first character of every block of four characters. The characters kept should be among 7. Expected frequency is
