For this assignment, you will solve the problem presented using Figure 7.17 located in our text and write a 2-3 page report that includes the following:

 

  • 2-3 pages of content minimum (does not include cover, abstract or references pages)
  • The paper must conform to full APA guidelines to include a cover page, abstract, headers, introduction, body paragraphs with appropriate headings/subheadings, conclusion, and a reference page.

Problem:  You want to build a hardware device to do block encryption in the cipher block chaining (CBC) mode using an algorithm stronger than DES. 3DES is a good candidate. Figure 7.17 shows two possibilities, both of which follow from the definition of CBC. Which of the two would you choose and why:

 

  1. For security?
  2. For performance?

 

You must fully explain and support your justification and reasoning.

 

FULL APA FORMATTING IS REQUIRED!
