Course Description

In this class, we will explore some of the topics in modern cryptography. This course is a graduate level course. 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 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.

Students will be required to give a short presentation on one of the cryptography topics not covered in the class. Potential topics will be mentioned in the class throughout the semester. Some example topics include: secret-sharing schemes, fully homomorphic encryption, identity/attribute based encryption, functional encryption, program obfuscation, verifiable computation, etc.

Grading Policy

Subject to minor tweaks throughout the semester.
