WebMar 5, 2010 · The Playfair cipher is a great advance over simple monoalphabetic ciphers, due to: The identification of digrams is more difficult than individual letters: i) In the Monoalphabetic cipher, the attacker searches in 26 letters only. ii) But using the Playfair cipher, the attacker is searching in 26 x 26 = 676 digrams.

Web1 Answer. 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.
