Course Outline

This course will discuss basic building blocks of modern cryptography. Tentative topics include encryption,
data integrity, authentication and identification, digital signatures, elementary number theory, randomness
and pseudo-randomness, cryptographic protocols, and real world security systems.
As a byproduct, you might become acquainted with some symbolic mathematics software.

Travel Advisory!

Based on the feedback forms from 2007, most students thought the course was way too hard.
A few thought it was worth the effort.
This leaves the lecturer puzzled as to why so many (approx. 85) insisted on taking it.
As for students in future generations of this course (and same lecturer) - caveat emptor!


Recommended Prerequisites

  • Linear Algebra
  • Probability
  • Algorithms
  • Computational Models
  • and most importantly, "mathematical maturity".


Based on final exam (70-80%) and homework assignments (30-20%).

Home Assignments

Homework submission is in singles or pairs. There will be a total of 3-4 problem sets consisting of both "dry" assignments
and a "wet" component (involving small Sage/Maple/Wolfram Alpha programs).
The homework portion of the grade is determined by the the weighted average of all assignments.
