Question TWO:(25 Marks) Simplified DES, which is a secure encryption algorithm developed by Professor Edward Schaefer, is an educational version of conventional DES. It has similar properties and structure to DES with much smaller parameters. Use the following parameters to generate the Sub-keys (Ki, K2) and the (Plaintext) for the given; initial key and Ciphertext.

Clearly, show the solution steps and make use of Charts attached in Appendix.​
