Abstract

In this paper, we present a new cube root algorithm in finite field $F_{q}$ with $q$ a power of prime, which extends the Cipolla-Lehmer type algorithms \cite{Cip,Leh}. Our cube root method is inspired by the work of Müller \cite{Muller} on quadratic case. For given cubic residue $c \in F_{q}$ with , we show that there is an irreducible polynomial with root such that is a cube root of . Consequently we find an efficient cube root algorithm based on third order linear recurrence sequence arising from . Complexity estimation shows that our algorithm is better than previously proposed Cipolla-Lehmer type algorithms.
