In 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 … See more Each letter is represented by a number modulo 26. Though this is not an essential feature of the cipher, this simple scheme is often used: To encrypt a message, each block of n letters (considered … See more In order to decrypt, we turn the ciphertext back into a vector, then simply multiply by the inverse matrix of the key matrix (IFK/VIV/VMI in … See more The basic Hill cipher is vulnerable to a known-plaintext attack because it is completely linear. An opponent who intercepts $${\displaystyle n^{2}}$$ plaintext/ciphertext character pairs can set up a linear system which can (usually) be easily solved; if it … See more Other practical "pencil-and-paper" polygraphic ciphers include: • Playfair cipher • Bifid cipher • Trifid cipher See more Let be the key and suppose the plaintext message is 'HELP'. Then this plaintext is represented by two pairs Then we compute See more When operating on 2 symbols at once, a Hill cipher offers no particular advantage over Playfair or the bifid cipher, and in fact is weaker than … See more • "Hill Cipher Web App" implements the Hill cipher and shows the matrices involved • "Hill Cipher Explained" illustrates the linear algebra behind the Hill Cipher • "Hill's Cipher Calculator" outlines the Hill Cipher with a Web page See more Web1 Answer.
