Answer:-

the blank using the AES algorithm, we need to perform the encryption process. Here are the steps:
Input text: 32 16 a8 88 23 0d 31 31 98 a2 e0 37 07
Cipher key: 2b 7e 15 16 28 ae d2 a6 ab 17 15 88 09 3c
Step 1:    32 23 98 07 16 0d a2 31 a8 31 e0 31 88 31 37 98
Cipher key (4x4) matrix: 2b 28 17 3c 7e ae 15 09 15 d2 88 3c 16 a6 09 3c
Step 2:    2b 28 17 3c 7e ae 15 09 15 d2 88 3c 16 a6 09 3c
SubBytes: e3 e2 8d 48 11 98 5d 52 be 2b 2a 31 c1 e5 e0 b8
