How do we send our own confidential information through secure channels, and how can we break codes to uncover the secret information of our adversaries? The mathematical field of cryptology is dedicated to answering such questions. In this course we will study breakthroughs in cryptology, from secret messages in the ancient world and the Enigma cipher in World War II, to modern cryptosystems that facilitate online commerce. Along the way, you will develop a sophisticated understanding of how numbers interact and develop the ability to communicate messages secretly and mathematics clearly. Restricted to first-year students. Not eligible for CR/NCR option.

Prerequisite: High school level algebra.
Exclusions: Not intended for students in a Mathematics Specialist or Major program.
Contact hours: 24 seminar; Total scheduled hours for the course, not per week.

n = 3student contributedSt. George offerings only

This is a student-contributed aggregate, not an official University of Toronto record. It is also not a measure of how hard the course is — a course average moves with who enrols in it, not only with the material.

The newest observation is from Winter 2023. Instructors, weighting and exam format may all have changed since — treat this as history, not a forecast.

Per-term figures stay hidden until each term clears five contributors. 3 observations can support one honest number; they cannot support 3.

Assessment weightingNo syllabus we can lawfully use has been verified for this offering. Contribute yours and the breakdown appears here.

A current averageThe newest verified observation is from Winter 2023. Later terms have no confirmed result yet.

Per-term breakdownHeld back deliberately. Splitting 3 observations across terms would be false precision.

Instructor-level detailAverages are not split by instructor. At these sample sizes the difference between sections is noise, not signal.

Archive coveragePyko holds no past paper for this course. We do not host or distribute course files in any case; the archive is what lets these pages describe how a course is assessed.
