FHE-Related Comments on NIST First Call for Multi-Party Threshold Schemes

September 27, 2023


Yuriy Polyakov - Duality Technologies


In this talk, I will discuss the public comments prepared by Ahmad Al Badawi, Andreea Alexandru, Nicholas Genise, Daniele Micciancio, Yuriy Polyakov, Saraswathy R.V. and Vinod Vaikuntanathan (see for the detailed version of the comments). Our comments are for Fully Homomorphic Encryption (FHE) schemes based on LWE and Ring/Module LWE over power-of-two cyclotomic rings, since this is what is most commonly implemented in open-source libraries. Our comments can apply to other FHE schemes with different hardness assumptions as well (e.g., NTRU). The comments covered in my talk include: (1) Motivation for standardizing (Threshold) Fully-Homomorphic Encryption; (2) FHE use cases; (3) FHE schemes’ Threshold friendliness; (4) Open-source implementations.
