Course Calendar

See the course overview for details on the course content and prerequisites.

Textbook: This course will not use a textbook. (Most of the topics we will teach are too new to appear in textbooks.) Ron Rivest has compiled a comprehensive list of readings on cryptography and computer security. If you are interested in going deeper into any topic, or if you need ideas for your final project, these references are a great place to start.

Course policies: Please read them carefully. You are responsible for knowing and following all of the policies—especially the collaboration policy and the policy on AI assistants (GPT and friends). Please do not make us sad, and yourself even more sad, by violating the collaboration policy.

Warning: We may change any content on this website, including the calendar, at any time.
