WebCryptanalysis §. Cryptanalysis is the art of breaking codes and ciphers. When attempting to crack a Hill cipher, frequency analysis will be practically useless, especially as the size of the key block increases. For very long ciphertexts, frequency analysis may be useful when applied to bigrams (for a 2 by 2 hill cipher), but for short ... WebTo encrypt a message, each block of n letters (considered as an n-component vector) is multiplied by an invertible n × n matrix, against modulus 26. To decrypt the message, each block is multiplied by the inverse of the matrix used for encryption. The matrix used for encryption is the cipher key, and it should be chosen randomly from the set of invertible n …

WebThe Hill cipher is a linear transformation of a plaintext block into a cipher block. The above attack shows that this kind of transformation is easy to break if enough pairs of plaintexts and ciphertexts are known. Modern ciphers, in fact, always contain a non-linear component to prevent this kind of attacks.
