One limitation of symmetric block ciphers is that any message repetitions will show in the ciphertext. Cipher block chaining (CBC) is one solution to combat this problem. If using DES in CBC mode is the following statement true or false? Explain your answer "With DES-CBC, two identical plaintext blocks are mathematically guaranteed to be encrypted to two different ciphertext blocks."
