WebThe Hill Cipher, created by Lester Hill in 1929, is a cipher that has not been successfully decrypted in a ciphertext only attack [3]. Numerous attempts have been made over the years by various cryptanalysts, but to date no complete successes have been achieved for all block sizes of the key matrix when analyzing ciphertext only.
