Answer the questions about the CBC mode encryption as shown in

Answer the questions about the CBC mode encryption as shown in the following figure ( 20 points) Cipher Block Chaining (CBC) mode encryption 1) If two different Initialization Vectors (IVs) are used for encryption, what is the consequence for the corresponding ciphertexts? ( 10 points) 2) If one plaintext block is modified, what is the consequence for the ciphertext? ( 10 points)
