# SM468 Cryptography, codes, and information security Syllabus

```SM468 Cryptography, codes, and information security
Syllabus
Course coordinator: Max Wakefield
Fall AY2014
Text: “Introduction to Cryptography with Coding Theory” by Trappe and Washington 2nd edition
Computing Platform: MATLAB. The website http://www2.math.umd.edu/ lcw/MatlabCode/ has relevant scripts that will be useful.
Here are some notes about the material to be covered and the problems required for homework:
1. We may have more problems given that are not in the book. I will provide those at the time we cover
the material.
2. Many of the sections that just say read will have problems or projects that I will give out after we
cover that section.
3. Some problems will not be required as we may choose to not cover an entire section. We may also
decide to cover some sections or material that are not on this list. This syllabus is just a wish list of
the core material that we should cover.
4. The problems listed below in the table with numbers only correspond to the numbered exercises at the
end of the respective chapter. The problems listed with the prefix “CP” correspond to the “Computer
Problems” listed at the end of the chapter.
5. The dates of which we cover this material is TBA. We may want to spend more time on some subjects
and less on others.
6. Sections which are bolded below are central to the course.
