1. Using the same cipher key, apply each of the following transformations on two plaintexts that differ only in the first bit. Find the number of bits changed after each transformation. Each transformation is applied independently. a. SubBytes b. ShiftRows c. MixColumns d. AddRoundKey (with the same round keys of your choice)
2. Give a general formula to calculate the number of each kind of transformation (SubBytes, ShiftRows, MixColumns, and AddRoundKey) and the number of total transformations for each version of AES. The formula should be parametrized on the number of rounds.
