Secure MultiParty Computation: Protocols and Applications

Secure MultiParty Computation was first introduce by Yao in his seminal work in the mid 80s. MPC allows a group of parties to jointly compute a function on the union of the parties input without revealing anything else than the result of the function. Yao demonstrated that such protocols were possible, although not very practical. However, over the last ten years a lot of research and implementation work has been done on MPC and it has become more and more efficient, and is now on the edge of being practical. The focus of the PhD will be to improve existing protocols of MPC by reducing the communication and computation overhead as much as possible. But also to improve the existing SCALE-MAMBA MPC software developed in the KU Leuven and build applications on top of it.
