Use the AES cipher to encrypt the following plaintext:

Plaintext $=46697665204$F $6$E $655369782054776$F $20$

Given that the initial Key $=546$F $6$F $20456173795468697320697320$

Demonstrate your work step by step as follows:

i$.$ Write the key and the plaintext into initial states $($each $4$x$4$ bytes$)$ and do the initial

transformation.

ii$.$ Generate the round keys $($K$1,...,$ K$5).$

iii. Carry out the operations in each of the rounds from $1$ to $5$: substitute bytes, shift rows, mix

columns, and add roundkey.
