Question
Suppose that the output of the expansion permutation is the following 48-bit block:{1, 1, 1, 1, 1, 0, 1, 0, 1, 0, 0, 0, 0,
Suppose that the output of the expansion permutation is the following 48-bit block:{1, 1, 1, 1, 1, 0, 1, 0, 1, 0, 0, 0, 0, 0, 1, 0, 1, 0, 1, 0, 1, 1, 0,0, 0, 0, 0, 0, 0, 1, 0, 1, 1, 0, 1, 0, 1, 0, 0, 0, 0, 0, 0, 0, 1, 1,1, 1}.
Assume also that the sub-key for this round is:{0, 1, 1, 1, 0, 0, 0, 0, 0, 1, 1, 0, 1, 0, 0, 0, 1, 0, 1, 0, 1, 0, 1,0, 1, 0, 1, 1, 0, 1, 0, 1, 0, 0, 0, 1, 0, 1, 0, 1, 0, 0, 0, 0, 1, 0,0, 1}.
What is the 48-bit block that is passed to the S-boxes?
