초록

In this paper, we present a cube root algorithm using a recurrence relation. Additionally, we compare the implementations of the Pocklington and Padr\'{o}-S\'{a}ez algorithm with the Adleman-Manders-Miller algorithm. With the recurrence relations, we improve the Pocklington and Padr\'{o}-S\'{a}ez algorithm by using a smaller base for exponentiation. Our method can reduce the average number of $\mathbb F_q$ multiplications.

Abstract

In this paper, we present a cube root algorithm using a recurrence relation. Additionally, we compare the implementations of the Pocklington and Padr\'{o}-S\'{a}ez algorithm with the Adleman-Manders-Miller algorithm. With the recurrence relations, we improve the Pocklington and Padr\'{o}-S\'{a}ez algorithm by using a smaller base for exponentiation. Our method can reduce the average number of $\mathbb F_q$ multiplications.
