Cryptanalyse hill
WebIn classical cryptography, the Hill cipher is a polygraphic substitution cipher based on linear algebra.Invented by Lester S. Hill in 1929, it was the first polygraphic cipher in which it was practical (though barely) to operate on more than three symbols at once.. The following discussion assumes an elementary knowledge of matrices. WebQuestion: 1)Understanding of historical ciphers, symmetric encryption and authentication. (a) You are given a ciphertext that you are told was encrypted with one of the three historical encryption methods: transposition cipher, monoalphabetic cipher, polyalphabetic cipher. You are also told that the plaintext is an English language document.
