Assume the message M comprising of 5 blocks - M1, M2, M3, M4, M5 also assume you are employing a secret key encryption system and the corresponding ciphertext for each block as C1, C2, C3, C4, C5.

a) assume your using ECB electronic codebook mode. what happens to the ciphertext block if we invert just one bit of the plaintext in M3?

b) now assume you're using Cipher block chaining mode. what happens. to the ciphertext block if we in just one bit of plaintext in M3?

c)now assume you're using CTR counter mode. What happens to the ciphertext block if we invert just one bit of the plaintext in M3?
