3.) Show the first eight words of the key expansion for a 128-bit key of all zeros in an AES encryption scheme.

Use the algorithm as shown in the figure given below where the function g is given as follows

a.) a circular one byte circular left shift on the input word.

b.) a substitution on each byte of the word using the AES 256 byte S-BOX

c.) An EXOR with a Round Constant which for round one is given as (01,00,00,00) hex

Please show all detailed work and an explanation on each step, I need to do this pratice problem in order to do more. Thank you. I will rate thumbs up if you do this, other wise I will down rate, thank you.
