Cryptography, 400348202, Spring 2012/13
Course Description
This course provides an introduction to cryptography and
its relation to security.
It covers
classical cryptosystems, privatekey cryptosystems
(including DES and AES),
and publickey cryptosystems (including RSA).
The course also provides an introduction to integrity
and authentication.
Course Outcomes
 Students will be able to implement and cryptanalyze classical
ciphers.

Students should demonstrate a basic understanding
of modern privatekey cryptosystems and ways to cryptanalyze them.

Students should demonstrate a basic understanding
of modern publickey cryptosystems and ways to cryptanalyze them.

Students should demonstrate a basic understanding
of the mathematical concepts underlying modern
cryptography.

Students should demonstrate a broad understanding of the
field of cryptography and its relation to security.

Required Book

Introduction to Cryptography with Coding Theory,
second edition, PrenticeHall, 2006.
Other Materials
Slides from class and other related materials will be posted at the reading and homework assignments webpage.
Prerequisites
CS4 (4003334) and Discrete Math (1016265).
The Work
There are eight homework assignments, one per week
except for the first week and the week of the midterm.
Each homework assignment will
be collected and graded. Homework assignments are due on Wednesday
at 2pm,
and are usually posted at least six days before they are due.
The actual assignments will be available on
the reading and homework assignments
page.
Unless it is specifically stated otherwise,
you may work on and submit your homework alone or as a pair.
If you choose to work as a pair, both of you
should contribute significantly to every part of the
homework. You should submit only one copy of the homework with both
your names on it.
Whether you submit on your own or with a partner, discussing the homework
assignments and solution strategies with your classmates is encouraged.
However, the actual solutions should be completely your own.
You are also not allowed to look up the answers to your homework and
you should be able to explain all of your homework to the instructor.
No late assignments will be accepted. The lowest two homework assignments will be dropped.
However, a zero for cheating will not be dropped.
Midterm Exam
The midterm exam is
scheduled
for Monday, April 8, 14:0015:50, in class.
Final Exam
The final exam is scheduled for TBA.
Exams can not be made up except for real emergencies in which
case proper documentation (like a doctor's note) will be required
or if you can not take an exam because of religious reasons.
If at all possible, you should contact me prior to the exam. Oversleeping,
cars that don't start etc. do not constitute a valid excuse.
Evaluation
 50% Homeworks and the best of
 25% Midterm and 25% Final Exam or
 20% Midterm and 30% Final Exam.
Numerical grades will be converted to letter grades according to the following
scale:
> 88%: A; 77%88%: B; 66%77%: C; 55%66%: D; < 55%: F.
However, your final grade will never be more than one letter grade
higher than your (weighted) average exam grade.
In addition, if your (weighted) average exam grade is below 55%,
you fail the course.
Disputing Your Grade
If you feel that an error was made in grading your homework or exam,
you have one week from the moment the graded work was handed back to dispute
your grade.
Students with Disabilities
RIT is committed to providing reasonable accommodations to students with
disabilities. If you would like to request accommodations such as special
seating or testing modifications due to a disability, please contact the
Disability Services Office. It is located in the Student Alumni Union,
Room 1150; the Web site is
http://www.rit.edu/dso.
After you receive accommodation approval,
it is imperative that you see me during office hours so that we can work out
whatever arrangement is necessary.
Academic Honesty
The
DCS Policy on Academic Honesty will be enforced.
You should only submit work that is completely your own.
Failure to do so counts as academic dishonesty and so does
being the source of such work. Submitting work that is in large part not
completely your own work is a flagrant violation of basic ethical behavior
and will minimally be punished with failing the course.
