I need some help with this question

Transcribed Image Text:(4 points) In this problem we will work through a round of DES.
For notational simplicity, assume it is the first round.
Please enter all answers as strings of 0's and 1's.
The input is the 64 bit block
0000100000010000000000000000000010010000000000000000000000000000
Suppose that the subkey for the current round is this 48 bit number:
000000000000000000000010000000000000000000000000
What does the 64 bit state look like after the IP transformation is applied to the input?
0000000001100010000000000000000000000000100000000000000
Now find Lo and Ro, the left and right halves of the state.
Lo =
00000000000110000100000000000000
Ro = 00000000000000100000000000000000
