I've added the initial list of articles for the seminar.

Applied Multiparty Computation and Fully Homomorphic Encryption




(Winter Term 2022/2023)

CISPA / Saarland University





Fully-Homomorphic Encryption (FHE) schemes and Multi-Party Computation (MPC) are fundamental tools in modern cryptography.

For decades FHE and MPC schemes have been abstract concepts living in the realm of cryptographic theory. 

In recent years those systems have seen major improvements in terms of efficiency and practicality.

In short, FHE and MPC have become practical enough to be considered for applications in private delegation of machine learning models and applications to privacy-preserving distributed Genome-wide association studies.

This seminar is concerned with currently implemented applications and practical aspects of FHE and MPC. 

By the end of the seminar, participants should possess fundamental knowledge about FHE and MPC and should know the 
state-of-the-art of libraries and developer tools that are available nowadays. 
In particular, participants should have an overview of what is currently possible to achieve and at what cost using FHE and MPC techniques.



During the seminar, students are required to read, understand and present advanced cryptography papers.
Hence, it is required that a student has completed a cryptography course and is fluent in linear and abstract algebra.


The seminar will take place online.
