Suppose we will use Advanced Encryption Standard (AES) to encrypt a block of plaintext and
the known round key for round 7 is:
B5 8D BA D2 31 2B F5 60 7F 8D 29 2F EA D2 73 21
Please calculate the first four words of the round key for round 8 by following the steps below:
(1) What is the ‘temp’ value after RotWord?
(2) What is the value after SubWord?
(3) What is the value after XOR with Rcon?
(4) What is the first word (i.e. the first 4 bytes) of the round key for round 8?
(5) What is the third word (i.e. the third 4 bytes) of the round key for round 8?
