WebAs with Playfair, the strength of the Hill cipher is that it completely hides single letter frequencies. T F 12. A scheme known as a one-time pad is unbreakable because it produces random output that bears no statistical relationship to the plaintext.

WebThus a 3 x 3 Hill cipher hides not only single-letter but also two-letter frequency information. Although the Hill cipher is strong against a ciphertext-only attack, it is easily broken with a known plaintext attack.
