One important property which makes DES secure is that the S-boxes are nonlinear. In this problem we verify this property by computing the output of S1 for several pairs of inputs.

Question-1 What is the output of the first round of the DES algorithm when the plaintext and the key are both all zeros?

Question- 2 What is the output of the first round of the DES algorithm when the plaintext and the key are both all ones?
