AI总结:

本文基于埃尔米特曲线提出Hermitian-lifted Codes,通过特殊单项式构造高可用、速率常数有界的纠删本地恢复码,利用直线与曲线交点构成恢复集。

摘要:

本文基于埃尔米特曲线构造了具备高可用性且速率为常数有界的纠删本地恢复码。这类新码被称为Hermitian-lifted codes(埃尔米特提升码),属于求值码,其求值集合为仿射曲线上的$\boldsymbol{\text{F}}_{q^2}$有理点集。创新点在于待求值的函数:它们是一类特殊的单项式,在与埃尔米特曲线相交的直线上限制为低次多项式。由此,经过给定点的任意直线上的点所对应的位置,可作为该点对应位置的恢复集。

英文摘要:

In this paper, we construct codes for local recovery of erasures with high availability and constant-bounded rate from the Hermitian curve. These new codes, called Hermitian-lifted codes, are evaluation codes with evaluation set being the set of $\mathbb{F}_{q^2}$-rational points on the affine curve. The novelty is in terms of the functions to be evaluated; they are a special set of monomials which restrict to low degree polynomials on lines intersected with the Hermitian curve. As a result, the positions corresponding to points on any line through a given point act as a recovery set for the position corresponding to that point.
