The Hill Cipher

WebThe Hill cipher is a classical block cipher based upon matrix multiplication. In 2007, Bauer and Millward completed a ciphertext-only attack in which they recovered the individual rows of the encrypting matrix to reduce the work previously necessary to recover the entire matrix at one time. In 2015, Leap et al. improved WebThe Hill cipher The Playfair cipher is a polygraphic cipher; it enciphers more than one letter at a time.

"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 " - Hill cipher examples
