WebFirst, the plain letters are substituted by selected letters (commonly pairs of letters are used, in which case the cipher is called a "biliteral cipher"). Secondly, such letters are then super-encrypted by a transposition. Let's study an example of a Fractionation System. For instance, let's encrypt "cryptography" using the key word "orange". WebLater versions of the substitution cipher used a keyword to create a keyed alphabet which can be used for the plaintext alphabet, the ciphertext alphabet or both. Where word divisions are kept the American Cryptogram Association (ACA) refers to the monoalphabet substitution cipher as the "Aristocrat" cipher. Another type of cipher, the ...
WebJan 12, 2024 · During the 16th century, Vigenere designed a cipher that was supposedly the first cipher which used an encryption key. In one of his ciphers, the encryption key was repeated multiple times spanning the entire message, and then the cipher text was produced by adding the message character with the key character modulo 26.
