Problem Set $1$: AES Encryption

$1.$ Scenario: Encrypt the plaintext message using AES with the following key: Plaintext Message:

Key:

$2.$ Tasks:

$-$ Perform all AES steps for one round of encryption:

$1.$ Construct the state matrix.

$2.$ Apply the following transformations:

$-$ Add Round Key $0$

$-$ SubBytes $($use S$-$Box$)$

$-$ ShiftRows

$-$ MixColumns

$-$ Add round key $1.($You have to compute round key $1)$

$3.$ Show intermediate results after each step.

$-$ Highlight your final encrypted state matrix.
