Next meetup scheduled: Crypto Dark Matter on the Torus: Oblivious PRFs from shallow PRFs and FHE
on November 23rd, 4pm CEST (Paris, FR)
Greetings cryptographers!
🗓️ The next FHE.org meetup is scheduled for Thursday, November 23rd at 4pm CEST (Paris, FR).
The meetup features Prof. Alex Davidson, Assistant Professor in the Computer Science Department at Universidade NOVA de Lisboa presenting Crypto Dark Matter on the Torus: Oblivious PRFs from shallow PRFs and FHE.
Here is the link to register:
Abstract
In this talk, Prof. Alex Davidson will describe a novel construction of an oblivious pseudorandom function (OPRF) protocol with post-quantum security guarantees, based on (T)FHE and low-depth pseudorandom functions. Classical OPRFs are being standardised by the Internet Engineering Task Force, and their applications (including the Privacy Pass and OPAQUE protocols) require high-performance solutions. While previous post-quantum candidates focus more on feasibility, Alex will show that FHE-based OPRFs appear to provide a viable way forward for realising practically efficient constructions.
About the speakers
Alex is an Assistant Professor in the Computer Science Department at Universidade NOVA de Lisboa. His research focuses on applications of cryptography in the Internet setting, and concrete constructions of primitives from lattice-based assumptions. His recent work focuses on building practical privacy-preserving protocols for data aggregation and retrieval scenarios.
Resources from last meetup
We’re happy to have had Jaehyung Kim last week presenting on FHE ring packing - affordable and convenient.
You can access those resources on the FHE.org website here.
