Course Description

In this class, we will introduce some topics in modern cryptography. The course is theoretical in nature, with emphasis on proofs and algorithmic reductions (even when discussing applied topics).  No prior background in cryptography is assumed. However, students should have some mathematical maturity and be comfortable working with definitions and proofs. Some of the topics we will cover include: one-way functions, pseudo-randomness, symmetric encryption, hash functions, message integrity, digital signatures, and public-key encryption. Time permitting, we may also dive into zero-knowledge proofs and secure multiparty computation.

Grading Policy

Text Book

The prescribed textbook for this course is Katz and Lindell's text Introduction to Modern Cryptography (some copies available in the library). See course webpage for previous offerings of this course for several free and excellent educational material on cryptography.
