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.

The determinant of the matrix we are inverting is ac - bd (mod 26) = 15*19 - 12*2 = 261 = 1 (mod 26). We also need to find the inverse of the determinant (1), which luckily in this case is 1 because 1 is its own inverse. how to search in array in c++

WebAug 12, 2024 · The Hill cipher is vulnerable to known-plaintext attack. 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.
