# HEMat

HEMat is a software package for performing a secure outsourced matrix computation using homomorphic encryption (https://dl.acm.org/citation.cfm?id=3243837). 

## Setting up HEMat library 

### Dependencies

Our library requires a c++ compiler and the following libraries:

* `GMP` (GNU Multi-Precision library, >= 6.1.2), which is available at https://gmplib.org,

* `NTL`  (>=11.0.0), which is available at http://www.shoup.net/ntl/,  (with pThread)

* `HEAAN`,  which is an implementation of the paper "Homomorphic Encryption for Arithmetic of Approximate Numbers" (https://eprint.iacr.org/2016/421.pdf). We refered to the underlying HE library in the "src" folder. You can build the libarary “libheaan.a" by typing "$make all" in the "/src" directory.

### Installing HEMat library

HEMat is easy to configure and build in Linux and macOS. 

First, clone this Github repository into a directory of your choice:

```sh

git clone https://github.com/K-miran/HEMat

```

You can then install our library by the following work with command line tools in the "/HEMat" directory. :

```sh

cd HEMat

make new

```

This will build our library "libHEMat.a".  

## Running a test source code

The program will run with several secure matrix algorithms (e.g. matrix addition, multiplication, transposition, and rectangular matrix multiplication).  

For example, you run a test program in the the directory by doing as follows: 

```sh

make test

./foo 

```
