  • Overview

    This course is intended for graduate students interested in data privacy, with a particular focus on differential privacy. Differential privacy offers a strong guaranteed bound on the increase in harm that a user may incur as a result of participating in a data analysis. The first part of this course will focus on some fundamental results about the theory of differential privacy and how to use it in concrete applications. The second part of the class will introduce students to EasyCrypt, a proof assistant designed for the verification of cryptographic primitives, and how to use it to verify cryptographic protocols and differential privacy algorithms.

    We will also experiment practically with these topics on different examples by using the EasyCrypt tool, which you can find here. Detailed instructions for installing EasyCrypt, and configuring Emacs to work with EasyCrypt, can be found here. There is an (incomplete and somewhat out of date) EasyCrypt Reference Manual.
