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 WebWe can use this to crack whatever cipher that is being used. 🔗. Let's assume in this instance that a Hill's cipher with a shift was used so that the enciphering algorithm looked like. C ≡mM +s C ≡ m M + s. 🔗. this means we will use. M ≡ m−1C+(−m−1s) M …

Once the attacker gets n plaintext/ciphertext pair it can break the cipher by solving a system of linear equations. Consider AES, it is not proved but considered secure against known-plaintext attack, see this question for details. And, also, key size itself doesn't represent the security. happy mother fur
