WebInvented by Lester S. Hill in 1929, the Hill cipher is a polygraphic substitution cipher based on linear algebra. Hill used matrices and matrix multiplication to mix up the plaintext. 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 …

Decrypting Hill

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. WebAbout.
