FHE Binder

Built with pybind11

This packages packs three different FHE libraries: HEAAN, MS-SEAL, and PALISADE
Beware these back-end libraries are being actively developed and open to the changes in their API, build process, and functionality.

Conda environment

in the root directory of the package:

$ conda env create  --file requirements.yml

Buildling HEAAN

0. You can find the HEAAN source code under ./HEAAN/
1. It requires, of course, essential development tools such as C++ compiler and Cmake. Install them via apt: $ sudo apt install build-essential cmake
2. You also need a Python environment. We tested it under conda Env and Python 3.9
3. One specific library HEAAN depends on is GMP. GMP 6.2.1 worked fine for us.

cd gmp-6.2.1
./configure SHARED=on 
make
make check  # GMP developers strongly recommend doing this
(sudo) make install 

If you encounter a version number mismatch error message like:

GMP version check (6.2.1/6.2.0)
*** version number mismatch: inconsistency between gmp.h and libgmp

during building NTL library, try installing GMP library system-wide via apt instead.

sudo apt install libgmp3-dev 
sudo ldconfig

You also need the Number Theory Library NTL. We tested NTL 11.5.1. NOTE that you need to add the flag NTL_GMP_LIP=on to Configure.

cd NTL/src
./configure SHARED=on NTL_GMP_LIP=on
make
make check  # optional
(sudo) make install

Now you are ready to build HEAAN. (need to be compiled with -fPIC)

cd HEAAN/lib
#    # Make sure in `src/subdir.mk`, there's the `-fPIC` option in g++ call (Line 59)
make 
# And run the test example
cd run
make
./TestHEAAN bootstrapping

Building SEAL

Provided that build-essential, cmake, and python are available, building SEAL library is simple.

SEAL requires more recent version of CMake than what is available on Ubuntu18.04. Within conda environment, install newer cmak with pip as: pip install --upgrade cmake

cd SEAL
cmake -S . -B build -DSEAL_USE_MSGSL=OFF -DSEAL_USE_ZLIB=OFF -DSEAL_USE_ZSTD=OFF
cmake --build build

Now, back in the root dir, run:

python3 setup.py build_ext -i

to install Fase.

You will see HEANN.cpython.....so and seal.cpython.....so among others.
