In this talk, I will first motivate circuit-based private set intersection (PSI) as a promising tool for jointly conducting privacy-preserving analyses over databases of two or more parties. Then, I will give an overview of constructions that substantially improved the performance of such cryptographic protocols over the last decade. Finally, I will touch on circuit compilation for secure computation, which is essential to automatically generate representations of analytic functions that can be efficiently evaluated on "encrypted" data.
Christian Weinert is a lecturer in the Information Security Group (ISG) at Royal Holloway, University of London. Before, he was a doctoral researcher (2016/09 – 2021/08) and postdoctoral researcher (2021/09 – 2022/02) in the Cryptography and Privacy Engineering Group (ENCRYPTO) at the Department of Computer Science of TU Darmstadt, Germany. His research focuses on the design, implementation, and evaluation of privacy-preserving protocols at large scale. During his bachelor and master studies, he worked in the area of long-term storage.
