WebThe Hill cipher is a multi-letter cipher. It is based on Linear Algebra operations, specifically matrix operations. It was created in 1929 by the mathematician Lester Hill. Some concepts you might want to revisit are matrix multiplication and inversion. The Hill cipher WebJan 2, 2024 · Known plaintext attack. Because the Hill cipher is a linear cipher, it is vulnerable to a known plaintext attack. For a secret key with shape , we need pairs of known plaintext and ciphertext blocks, each of length . The resulting equations no only need to be linear independent in general but in modulo too. If not, the calculus of the inverse ...
