Question 1 options:

Consider the following 32-bit block: {0, 0, 1, 1, 0, 0, 0, 1, 0, 1, 0, 1, 0, 1, 0, 1, 0, 0, 0, 1, 1, 1, 0, 0, 1, 1, 1, 0, 1, 1, 1, 1}.

Assume that this block is the input of the "g" function of the AES key schedule during the 10th round.

What is the output of "g"?

Question 2 options:

Consider the following 32-bit block: {0, 0, 1, 0, 0, 1, 1, 0, 1, 1, 1, 1, 1, 1, 0, 0, 0, 1, 1, 0, 0, 1, 1, 0, 1, 0, 1, 0, 1, 1, 0, 0}.

Assume that this block is the input of the "g" function of the AES key schedule during the 9th round.

What is the output of "g"?

Question 3 options:

Consider the following 32-bit block: {0, 1, 1, 0, 1, 0, 0, 1, 1, 1, 1, 1, 0, 0, 0, 1, 1, 0, 1, 1, 1, 0, 0, 1, 1, 0, 1, 0, 0, 1, 0, 1}.

Assume that this block is the input of the "g" function of the AES key schedule during the 7th round.

What is the output of "g"?

Question 4 options:

Consider the following 32-bit block: {1, 0, 0, 0, 0, 0, 0, 1, 0, 1, 0, 1, 1, 0, 1, 0, 1, 0, 1, 1, 0, 0, 0, 0, 0, 1, 1, 0, 0, 0, 1, 1}.

Assume that this block is the input of the "g" function of the AES key schedule during the second round.

What is the output of "g"?
