This problem will be a partial walkthrough of a single round of the encryption process used by AES.

The input to that round will be the $8$ digits of your Banner ID $($in hexadecimal$),$ repeated twice. Hint: don't forget that the two$-$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:

$00030003$

$00040004$

$01050105$

$02060206$

You will do this in the following steps:

a$)$ Give the initial state created from your Banner ID$.$

b$)$ Run this state through the SubBytes stage.

c$)$ Run the result of that through the ShiftRows stage.

d$)$ Run the result of that through the MixColumns 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.

BANNER ID: $00269186$
