# Distributed Point Function

This crate gives the basic functionality of a cryptographic distributed point function, a cryptographic construction first proposed by Gilboa and Ishai [GI14] and later improved by Boyle, Gilboa and Ishai [BGI16].

With this primitive a unit vector $\vec{e}$ of size $N$ (that is, a vector with zeros in all coordinates except for a single coordinate) can be additively secret shared between two parties such that each share can be described using a key of size $\log N$ while merely assuming the existance of one-way-functions.
