Hill cipher 2x2 examples
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. Each letter is first encoded as … WebOutput example of the Hill cipher implementation Advantages of Hill cipher. The main advantage of the Hill cipher is that it hides single letter frequency. Depending on how big the matrix that represents the key is, the more letter frequency it hides. For instance, if you use a 3×3 matrix, it hides single letter and two-letter frequencies.
