Polygraphic cipher

WebHowever, the keyword length determines the periodicity in which alphabets are used. This periodicity is a major vulnerability of these types of ciphers. Polygraphic . This is a substitution technique that replaces a group of n plaintext symbols by a group of n ciphertext symbols. [R2] In doing so, the individual frequency of symbols is hidden. WebPolygraphic Ciphers Instead of substituting one letter for another letter, a polygraphic cipher performs substitutions with two or more groups of letters. This has the advantage of masking the frequency distribution of letters, which makes frequency analysis attacks much …
