Description
This course is an introduction to the basic theory and
practice of cryptographic techniques used in computer
security. We will cover topics such as encryption
(secret-key and public-key), digital signatures, secure
authentication, key management, cryptographic hashing, Internet voting
systems, copyright protection, and a bit of zero-knowledge protocols.
Prerequisites
The course requires a basic understanding of
probability theory. Some knowledge of modular arithmetic
will be helpful but not required. The course is intended
for advanced undergraduates and graduate students.
Textbook Information
We will be using the following books:
- Cryptography Theory and Practice, Second edition by D.
Stinson.
- Optional: Network Security, Second edition, by
C. Kaufman, R. Perlman, and M. Speciner.
- Optional: Applied cryptography by B. Schneier.
- Optional: Handbook of Applied Cryptography by A. Menezes,
P. Van Oorschot, S. Vanstone. Free!
and research papers handed out in class.
Sections
- There will be five sections given by the TA's during the
quarter.
- Sections will be held on Tuesdays in Gates B03 from
6:00pm - 6:50pm (live on channel E1) on the following dates:
- January 21,
- February 4,
- February 18,
- March 4,
- March 11.
- Attendance at the sections is optional.
Homework Assignments
- There will be four written
homework assignments and two programming projects.
- You may collaborate when solving the written
assignments, however when writing up the
solutions you must do so on your own.
- Both programming projects can be done in pairs.
- You must hand in all four homework assignments
and the two programming projects.
- Some of the assignments will contain extra credit
questions. You must solve extra credit questions
on your own.
- Homework assignments will be graded on a scale of
0 to 10.
- Extensions: each student has a total of 48
extension hours throughout the quarter.
This automatic extension can be spent in units of 24 hours on any
of the assignments and projects. Please mark the submission
time for any late assignment.
- Homework will be due on Wednesdays in class or at 5pm in
the CS255 homework bin next to Gates 182.
- It is an honor code violation to consult solutions to
homework problems from previous CS255's.
Exams
There will be an in class final exam during finals week.
No midterm exam.
Students can choose from one of two dates for the in class
final exam.
Grading
Final placement in the class will be determined by the following formula:
0.4 H + 0.3 P + 0.3 F
- H is your average score on the four
written homework assignments.
- P is the weighted average grade on the two programming
projects.
- F is your final exam score.
