Difficulty: This is an introductory course in cryptology, that is, the subject of how to make ciphers (cryptography) and break them (cryptanalysis). The math used is heavy on modular arithmetic, which will be covered in some depth. It also makes some use of elementary counting and probability, plus a tiny bit of linear algebra and matrices. It is not intended as a substitute for a serious abstract algebra or number theory course.
Other expectations This is a 4-credit course, so I would guess that the average student should spend about 8 hours per week outside of class to get a decent grade. Part of this time each week would be well-spent making a first pass through the material in the book that we anticipate to cover in class that week, so that you can bring your questions/confusions to class and ask about them.
