3. This problem will be a partial walkthrough of a single round of the encryption process used by AES. The input to that roundwill be the 8 digits of your Banner D (in hexadecimal), repeated twice. Hint: don't forget that thetwo-dimensional state is created in column major format. For example, if your ID were 00123456, the round input state would be the following two-dimensional hexadecimal state: 00 03 00 03 00 04 00 04 01 05 01 05 02 06 02 06 You will do this in the following steps: a. Run this state through the SubBytes stage. b. Run the result of that through the ShiftRows stage. c. Run the result of that through the Mix Columns stage. Due to the complexity of MixColumns, you are only required to show the result for the first element (that is, the first row and column of the resulting state matrix), much like I did in my lecture. Also, you are required to show your work for this stage, as it will help with partial credit. 3. This problem will be a partial walkthrough of a single round of the encryption process used by AES.
