Fast GPGPU-Based Elliptic Curve Scalar Multiplication

Eric M. Mahé and Jean-Marie Chauvet

Abstract

This paper presents a fast implementation to compute the scalar multiplication of elliptic curve points based on a ``General-Purpose computing on Graphics Processing Units'' (GPGPU) approach. A GPU implementation using Dan Bernstein's Curve25519, an elliptic curve over a 255-bit prime field complying with the new 128-bit security level, computes the scalar multiplication in less than a microsecond on AMD's R9 290X GPU. The presented methods and implementation considerations can be applied to any parallel architecture.
