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. WebTo encrypt the text using hill cipher, we need to perform the following operation. D (K, C) = (K-1 * C) mod 26 Where K is the key matrix and C is the ciphertext in vector form. Matrix multiplication of inverse of key matrix K and ciphertext C generates the decrypted plain text. Steps For Decryption Step 1: Calculate the inverse of the key matrix.
WebHill Cipher is a historical encryption method based on matrix multiplications. It is an early adaption of block ciphers. That's why, it is still strong against brute force attacks even today....
