HElib
=====

HElib is a software library that implements [homomorphic encryption] [6] (HE).
Currently available is an implementation of the
[Brakerski-Gentry-Vaikuntanathan] [1] (BGV) scheme, along with many
optimizations to make homomorphic evaluation runs faster, focusing mostly on
effective use of the [Smart-Vercauteren] [2] ciphertext packing techniques and
the [Gentry-Halevi-Smart] [3] optimizations. See [this report] [7] for a
description of a few of the algorithms using in this library. Starting
December 2014, the library also includes [bootstrapping] [8].

At its present state, this library is mostly meant for researchers working on
HE and its uses. Also currently it is fairly low-level, and is best thought of
as "assembly language for HE". That is, it provides low-level routines (set,
add, multiply, shift, etc.), with as much access to optimizations as we can
give. Hopefully in time we will be able to provide higher-level routines.

This library is written in C++ and uses the [NTL mathematical library] [4]
(version 9.0.1 or higher). As of March 2015, it also supports multi-threading.
