WebAbout this Algorithm. The Hill cipher was invented by Lester S. Hill. Hill cipher is a polygraphic substitution cipher based on linear algebra. Each letter is represented by a number modulo 26. Often the simple scheme A = 0, B = 1, …, Z = 25 is used, but this is not an essential feature of the cipher. To encrypt a message, each block of n ... WebI know with other matrices, e.g. for the determinant there is usually a formula, such as: a x d - b x c However, for the Hill Cipher I am completely lost. I have done the following: a) found the inverse of K: K inverse = (-3 5) (2 -3) b) Found "KFCL": KFCL = (10 5) (2 11) c) The next step (mod 26) confuses me.
