Find the final sequence of bits in hex format after passing the initial sequence through different steps (boxes) of the DES.
Follow the step by step procedure and one by one pass the sequence of bits through the series of boxes and obtain the final result.
- Convert the given sequence of bits in binary form and retrieve the 32 bit sequence.
- Passing through the Expansion D-box, we get a 48-bit sequence.
- Making groups of 6-bits together and passing the 8 groups through the 8 different s-boxes, we finally get the 32-bit sequence. See here for how to use S-boxes.
- Convert the sequence into hex.
