Independent Keys

Question 1

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.

Question 2

Write 7-8 pages in length excluding the title and reference pages about the following:

• Background about Cryptography (include a history of Cryptography and the needs for that)
• The relationship between Cryptography and the CIA tried
• The use and importance of cryptographic functions such as encrypt, decrypt, and manipulate data, network communications, etc.
• The use and function of the most common cryptographic protocols: DES, 3DES, AES, RSA, etc. ( All need to be described adequately and how each works logically)
• The use of hashing (importance of that and how it helps to promote security). Also, you need to describe the hashing protocols such as MD5,SAH256, etc…
• How Diffie-Hellman protocol works step by step and (Picture or image would be preferred in addition to the explanation), the importance of this protocol.

Be sure your paper adheres to the academic writing standards and APA style guidelines, citing credible references as appropriate.

It is strongly encouraged that you submit all assignments to the TurnItIn Originality Check prior to submitting it to your instructor for grading. If you are unsure how to submit an assignment to the Originality Check tool, review the TurnItIn Originality Check. The similarity should be less than 20%.
