Q1]: Consider the following problem that provides a numerical example for some steps involved in the encryption using DES. Let's use the same bit pattern for the key (K) and the plaintext, namely (01 2 3 4 5 6 7 8 9 A B C D E F) a. (35 points) Derive subkey (K1); the subkey of the first round. b. (30 points) Derive Lo (Left half) and RO (Right half) from the plaintext. C. (35 points) Calculate E[RO] K1. Note: all needed tables are provided in next pages.
