Final Project

Steps

• Preliminary Part (10 points): Binary Numbers and ASCII, One-Time Pads and Pseudo-random Bit Generation - Chapter 2.8 - 2.10.
  Requirements:
  • Read chapters 2.8 - 2.10 (pp.38 - 43)

  • Create your own example that generates random key using Blum-Blum-Shub(BBS) pseudo-random bit generator. See example on page 43. Document the steps in word file.

  • Submission: Due day Wed Nov 21 by 11 AM (start of the class). I will check this part in class. You can write a program that implements the algorithm, but it is not required. You will see that some steps are similar to steps you performed in RSA implementation.

• Main Part: Data Encryption Standard - DES: Chapter 4

  • Step 1 (65 points): Introduction and Simplified DES (4.1, 4.2 pp. 113 - 118)
    Requirements: Create 2 examples demonstrating simplified DES encryption/decryption process. Choose the same S-boxes (S1 and S2) that are used in the textbook on page 116. For this step you only need to perform 2 rounds. Document all steps in Word file.
    Due Day: Wed Nov 28 by the end of the class.

  • Step 2 (15 points): Modes of Operations: ECB and CBC: 4.5.1 and 4.5.2. Requirements: Create your own example to demonstrate each mode.
    Due Day: Monday Dec 3 by the end of the class.

  • Step 3 (10 points): Computer Problem 1(a) and 1(b) p. 149: Write a program that performs one round of the simplified DES-type algorithm presented in Section 4.2
    Due Day: Wed Dec 5 by the beginning of the class your program must be ready for testing.

    Use TESING QUIZ to test your program. Submit your program and the testing quiz results.

    VERY IMPORTANT: If you didn't write the program, you still have to do the testing quiz. You will receive two grades - one for final project and one for the testing quiz. The grade for the testing quiz will be posted under quizzes/exams category as I did for the previous programming assignments.

• Bonus 1(10 points): Program 2(a). Due Day Friday Dec 7

• Bonus 2:(10 points): Read History and Design Considerations of AES (p.151-152, 5.4: p. 161) and Secure Hash Algorithm overview (8.1 pp.219-220 and 8.3 overview part only p.224-225) and create a short Power Point presentation. Due Day Friday Dec 7
