HEMat is a software package for performing a secure outsourced matrix computation using homomorphic encryption (https://dl.acm.org/citation.cfm?id=3243837).
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.
HEMat is easy to configure and build in Linux and macOS.
First, clone this Github repository into a directory of your choice:
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. :
cd HEMat
make new
This will build our library "libHEMat.a".
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:
make test
./foo
