Consider the 3-bit block cipher in Table 8.1. Suppose the plaintext is 100100100.
(a) Initially assume that CBC is not used . What is the resulting ciphertext?
(b) Suppose Trudy sniffs the ciphertext. Assuming she knows that a 3-bit block cipher without CBC is being employed (but doesn't know the specific cipher), what can she surmise?
(c) Now suppose that CBC is used with IV =Ill. What is the resulting ciphertext?
