Next meetup scheduled: Private set intersection via somewhat homomorphic encryption

October 28th, 6pm Paris time

Hello fellow cryptographers!

Our next meetup is scheduled for Thursday, October 28th at 6pm Paris time. Here is the link to register:


Somewhat/Fully Homomorphic Encryption (SHE/FHE) is a versatile tool for many cryptographic applications. In this talk, we show how to exploit SHE/FHE to build Private Set Intersection (PSI) protocols where two parties wish to compute the intersection of their respective private sets. We discuss the general framework of such protocols and the state-of-the-art optimizations including the most recent results from ACM CCS’21.


Ilia Iliashenko is a research engineer at Ciphermode Labs. He obtained his PhD in 2019 under the supervision of Prof. Frederik Vercauteren and Prof. Bart Preneel and then spent two years as a postdoctoral researcher at imec-COSIC, KU Leuven, Belgium.
His research interests are focused on secure computation methods including fully/somewhat homomorphic encryption and multi-party computation. Ilia published 11 research papers on SHE/FHE that were/will be presented at major cryptographic conferences such as Eurocrypt, CHES, and ACM CCS. In 2018 and 2019, Ilia was an intern at Microsoft Research, Redmond Lab, working on implementation of the CKKS/HEAAN scheme in the SEAL library.

See you then and please share the link!
