Work out a numerical example of encryption using a one-round version of DES, by following the Slides 53-60 of Lecture02. Start with the same bit pattern for the key K and plaintext, namely: in hexadecimal notation: in binary notation: 9ABDCFE012 34567 8 0001 0010 0011 0100 0101 0110 01111000 a. Derive KI, the first-round subkey using the Slide 60 of Lecture02. b. Derive Lo, RO. c. Expand Ro to get E[Ro], where E.] is the expansion function on the Slide 55 of Lecture02 d. Calculate A E[RO] YOR K1. Work out a numerical example of encryption using a one-round version of DES, by following the Slides 53-60 of Lecture02.
