HEMat is a software package for performing a secure outsourced matrix computation using homomorphic encryption (https://dl.acm.org/citation.cfm?id=3243837).
HEMat is easy to configure and build in Linux and macOS.
Clone this Github repository into a directory of your choice:
git clone https://github.com/K-miran/HEMatOur 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 "/HEAAN" directory.
First, compile the dependency -- HEAAN library
cd HEMat/HEAAN/
make allYou can then install our library by the following work with command line tools in the "/HEMat" directory. :
cd HEMat/HEMat
make newThis 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
