Parametrizations for Families of ECM-friendly curves

Alexandre Gélin, Thorsten Kleinjung, and Arjen K. Lenstra

Abstract

We provide a new family of elliptic curves that results in a one to two percent performance improvement of the elliptic curve integer factorization method. The speedup is confirmed by extensive tests for factors ranging from 15 to 63 bits.
