Suppose IV = 8’h77. Determine the ciphertext for plaintext = “HELLO” using RSA in CBC mode and use public key e = 5 and n = 91. For example, the first P0 = 72 = 8’h48 is XORed with 8’h77 before it is encrypted to generate ciphertext C0 ; then P1 = 8’h45 is XORed with C0 before it is encrypted to generate C1 , etc.
