我们提出了有限域上亏格为2的超椭圆曲线的一个约化方程。qofq元素,其特征不同于2和5。我们确定的同构类的亏格-2超椭圆曲线有一个?q-有理Weierstrass点这些结果在超椭圆曲线密码学中有应用。
We propose a reduced equation for hyperelliptic curves of genus 2 over finite fields ?qofqelements with characteristic different from 2 and 5. We determine the number of isomorphism classes of genus-2 hyperelliptic curves having an ?q-rational Weierstrass point. These results have applications to hyperelliptic curve cryptography.
