If the determinant is 0, or has common factors with the modular base, then the matrix cannot be used in the Hill cipher, and another matrix must be chosen (otherwise it will not be possible to decrypt). Fortunately, matrices which satisfy the conditions to be used in the Hill cipher are fairly common.

WebDigraph frequency analysis of text encrypted by a Hill 2-cipher suggests that the cipher-text digraphs ( ) (use the first two letters of your first name, for example I would use (CI)) and ( ) (use the first two letters of your last name, for example I would use (MA)) correspond to the plaintext digraphs (TH) and (HE) in that order.

WebHill Ciphers Hill ciphers (invented in 1929) are a type of block cipher: the ciphertext character that replaces a particular plaintext character in the encryption will depend on the neighboring plaintext characters. The encryption is accomplished using matrix arithmetic. The encryption key for a Hill cipher is a square matrix of integers. shanghai index today newsWeb18 hours ago · Photo by Chris Cody.
