短块长PIR码

PIR Codes with Short Block Length

Sascha Kurz, Eitan Yaakobi

摘要:

本文研究了私有信息检索码。在$k$ -PIR码中,$s$信息比特以这样的方式编码,即每个信息比特具有$k$相互不相交的恢复集。在此范例下的主要问题是在给定$s$和$k$的值的情况下最小化编码位的数目,其中此值由$P(s,k)$表示。本工作的主要重点是分析$P(s,k)$的$s$和$k$的大范围参数。特别是,我们改进了一些现有的结果,这个值。

英文摘要:

In this work private information retrieval (PIR) codes are studied. In a $k$-PIR code, $s$ information bits are encoded in such a way that every information bit has $k$ mutually disjoint recovery sets. The main problem under this paradigm is to minimize the number of encoded bits given the values of $s$ and $k$, where this value is denoted by $P(s,k)$. The main focus of this work is to analyze $P(s,k)$ for a large range of parameters of $s$ and $k$. In particular, we improve upon several of the existing results on this value.
