Description

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.

Cryptography
 Data

encryption is very important when it
entails transmission and its storage bearing in
mind the threats data might be exposed to in
modern networks.
 Data encryption is very essential for instance
when it involves privacy and security as far
computer passwords and bank cards


Encryption methods such AES, DES, 2DES and
3DES have applied to ensure security of the systems.
