Question 5 Suppose a plaintext message is exactly one block long and consists of all 0s. You produce a MAC tag using CBC-MAC with DES and an all-zero IV, and the key consisting of all zeros. A padding block will be appended to the plaintext which is 0x8 followed by enough 0s to ll out a second block, as per the CBC algorithm. What is the CBC-MAC tag?
