4. If an Initialization Vector (IV) plus a constant (i.e. IV, IV 1, IV 2, IV+3, etc.) is used to encrypt each corresponding successive plaintext block to generate ciphertext blocks, if there is an error of one bit which occurs during transmission in a ciphertext block, how many ciphertext blocks will be affected? (This is referred to as ‘counter mode’). If IV0 is the security of this cipher compromised more easily? Show transcribed image
