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.

"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 ... " - Hill cipher github
