超椭圆曲线的有效可计算自同态

Efficiently computable endomorphisms for hyperelliptic curves

David R. Kohel, Benjamin A. Smith

摘要:

椭圆曲线有一个众所周知的和明确的理论,用于构造和应用自同态,可以应用于提高性能的标量乘法。最近的工作已经扩展这些技术的超椭圆雅可比,但一个障碍是缺乏明确的曲线模型,以及一个有效的可计算的自同态。在超椭圆曲线的情况下,有有限的例子,大多数方法集中在特殊的CM曲线或在一个小的字段上定义的曲线。在这篇文章中,我们描述了三个无限族的曲线,承认一个有效的可计算的自同态,并给出算法,其有效的应用。

英文摘要:

Elliptic curves have a well-known and explicit theory for the construction and application of endomorphisms, which can be applied to improve performance in scalar multiplication. Recent work has extended these techniques to hyperelliptic Jacobians, but one obstruction is the lack of explicit models of curves together with an efficiently computable endomorphism. In the case of hyperelliptic curves there are limited examples, most methods focusing on special CM curves or curves defined over a small field. In this article we describe three infinite families of curves which admit an efficiently computable endomorphism, and give algorithms for their efficient application.
