Title:
Improved Key Pair Generation for Falcon, BAT and Hawk
Authors: Thomas Pornin
Abstract:In this short note, we describe a few implementation techniques that allow performing key pair generation for the Falcon and Hawk lattice-based signature schemes, and for the BAT key encapsulation scheme, in a fully constant-time way and without any use of floating-point operations. Our new code is faster than previously published implementations, especially when running on small embedded systems, and uses less RAM.
