You assume that T H → R H and H E → N I under the Hill cipher. The determinant of [ 19 7 7 4] is 19 ⋅ 4 − 7 ⋅ 7 = 1 ( mod 26), so the inverse exists and equals (using − 7 = 19 ( mod 26)) This allows us to compute the encryption matrix, and then the decryption matrix.

WebIn classical cryptography, the Hill cipher is a polygraphic substitution cipher based on linear algebra.Invented by Lester S. Hill in 1929, it was the first polygraphic cipher in which it was practical (though barely) to operate on more than three symbols at once.. The following discussion assumes an elementary knowledge of matrices. 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.

WebDecryption. In cryptography, encryption is the process of transforming information (referred to as plaintext) using an algorithm (called cipher) to make it unreadable to anyone except those possessing special knowledge, usually referred to as a key. The result of the process is encrypted information (in cryptography, referred to as ciphertext).
