WebJHU EP 605.206 - Introduction to Programming Using Python Introduction The Hill Cipher is a polygraphic encryption cipher that is based on some basic linear algebra and modular arithmetic. It can be broken via chosen plaintext attacks (CPA) where an attacker has access to a particular plaintext as well as its corresponding ciphertext.

Notice that the multiplicative cipher is just the 11 × case of the Hill cipher; individual letters are enciphered one at a time. invertible matrices modulo 26 (an invertible matrix is a matrix that has an inverse) can be used to encipher digraphs. 3. 22 ×

WebWhat makes the Hill cipher a block cipher is that each plaintext string is encrypted “at once:” the change of one letter in a plaintext block is likely to change all of the letters in the ciphertext block. Notice, for example, that changing the plaintext block he to ie changes the ciphertext block from GV to JA. Decryption
