The Data Encryption Standard (DES) is a symmetric-key algorithm for the encryption of electronic data, which you studied briefly in T215B. This task aims to assist you in learning more about the DES. Your answer should be as report which starting with introduction and ending with conclusion, the report should be within 1000 - 1200 words (long report, you should adhere to word count), the report should include sections and sub suctions, and at least one figure or table, your report must have proper citations and references. The body of your report should answer the following questions:
1. Define DES?
2. What is the history of DES?
3. Describe the key generation of the Simplified DES algorithm? It is preferable to answer it as a list of points.
