As part of your consulting assignment with the security staff of a local company, you have been asked to explain the Advanced Encryption Standard (AES), Data Encryption Standard (DES), and Triple DES (3DES). Prepare a presentation that consists of 8–10 slides to explain these terms. Your presentation should fully explain these concepts in the speaker notes and should answer the following questions:
- What are AES, DES, and 3DES?
- How does DES work?
- Why is 3DES now used?
- What is the future of 3DES?
- If three keys K1, K2, and K3 were used to perform 3DES encryption and K1=K3, how many independent keys were actually involved? Why?
- What is a nonce?
- What is a key distribution center?
Be sure to reference all sources using APA format. 8-10 slides
