How to Hash into Elliptic Curves

Thomas Icart

Abstract

We describe a new explicit function that given an elliptic curve $E$ defined over $\FF_{p^n}$, maps elements of $\FF_{p^n}$ into $E$ in \emph{deterministic} polynomial time and in a constant number of operations over $\FF_{p^n}$. The function requires to compute a cube root. As an application we show how to hash \emph{deterministically} into an elliptic curve.
