Hill created the Hill cipher, which uses matrix manipulation. With this we have a matrix operator on the plaintext: A = [ a b c d] which is used to encode, and then the decoder is the inverse of this: A − 1 = [ d − b − c a] For example we take the matrix: A = [ 2 3 3 5] Then the reverse will be: A = [ 5 − 3 − 3 2]
