Elliptic divisibility sequences and the elliptic curve discrete logarithm problem

Rachel Shipsey and Christine Swart

Abstract

We use properties of the division polynomials of an elliptic curve $E$ over a finite field $\mathbb{F}_q$ together with a pure result about elliptic divisibility sequences from the 1940s to construct a very simple alternative to the Menezes-Okamoto-Vanstone algorithm for solving the elliptic curve discrete logarithm problem in the case where $\#E(\mathbb{F}_q) = q-1$.
