# 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]](https://www.iacr.org/archive/eurocrypt2014/84410245/84410245.pdf) and later improved by Boyle, Gilboa and Ishai [[BGI16]](https://eprint.iacr.org/2018/707).
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.
