Hill cipher 2x2
WebHill Cipher. Pada penelitian ini menjelaskan mengenai proses enkripsi dan dekripsi untuk 26 karakter dengan menggunakan matriks 2x2 oleh Todd Douglas dan Dustin Helliwell (1997)[8]. Enkripsi pada SMS dengan menggunakan algoritma AES telah dilakukan oleh Rohan Rayarikar [9]. Hasil risetnya menunjukkan tidak adanya delay pada proses … In 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.
