(1) Consider the Output Feedback Mode (OFB). Suppose the encryption function, initialization vector and plaintext are as follows: Encryption Function: F(x) = (x+3) mod 17 IV = (0011)2 X₁ = (0111)₂ X₂ = (0101)₂ X3 = (0011)2 Show encryption and decryption for three rounds, i.e., "i" = 1, 2, 3. (2) Consider the previous question and perform encryption and decryption for three rounds using Cipher Feedback Mode (CFB). (1) Consider the Output Feedback Mode (OFB).
