1
Introduction

• CSCI284 Spring 2004
• GWU
• http//www.seas.gwu.edu/poorvi/Classes/CS284/

2
What we hope to learn

• Algorithms that form the basis of classical and
  modern cryptography their strengths and
  weaknesses
• The mathematical principles behind the strengths
  and weaknesses
• Mathematical exposition i.e. writing clearly and
  unequivocally why something is true
• Programming for cryptography

3
Student Evaluations

• Course grades will be based on
• HWs (75)
• Project (25)
• You may collaborate on HW solution, but not on
  the writing of the HW. If two HWs are found to be
  substantially similar, both students could be
  held liable for academic integrity violations
• HWs are due by the end of the day, Wed., nine
  days after they are assigned, by e-mail to the
  instructor poorvi_at_gwu.edu
• You may lose marks for disruptive behaviour in
  class.

4
What we will not learn

• Operating system and program security
• Network security
• Viruses and firewalls
• Advanced methods for breaking cryptographic
  primitives
• Hardware implementation of crypto

5
Texts and References

• The required test is listed on the website, and
  will be used to assign homework from
• Douglas Stinson, "Cryptography Theory and
  Practice", Second Edition, 2002
• Other references will be used, most will be
  provided in electronic or paper form.
