Abstract

Public-Key Encryption has had a significant impact by enabling remote parties to communicate securely via an insecure channel. This course provides an overview of how to construct public-key encryption, from classical to post-quantum, and how to use it to run computation on encrypted data.

Objective

The student is able to analyze and construct advanced encryption schemes, apply generic transformations that lift IND-CPA security to IND-CCA security, and understands modern post-quantum constructions, including those underlying fully homomorphic encryption. This prepares the student to read recent research papers in the field.

Content

We will start by presenting the notion of Public-Key Encryption with its various security guarantees and some basic constructions. Then we will present generic ways to enhance security, and finally show how to build KEMs. The second part of the course will be devoted to showing the post-quantum analogues of the schemes we already saw, with the goal to introduce the recently standardized ML-KEM and fully homomorphic encryption.

Examination

Type: session examination
Mode: oral 20 minutes

There will be voluntary graded homework assignment during the semester. The purpose of the assignment is to allow students to exercise and get feedback on their understanding of the course material. Successful completion of the homework assignment will result in bonus points for the final exam (up to 0.25 grade points).
