Running FHE CPP with SEAL

Install SEAL library system wide following instructions on: https://github.com/microsoft/SEAL

cd FHE_CPP_SEAL

cmake -B build

cmake --build build

./build/bin/shelfi

he-encryption-shelfi

Benchmarking for various crypto-systems (e.g. Paillier, CKKS) integrated with a federated learning architecture

FHE_CPP: cpp only implementation for CKKS

Pailler_Offline_Online_CPP: cpp only implementation for Pailler (offline + online)

palisade_pybind: implementation of private weighted average integrated with underlying schemes with python wrapper and bindings.

Dependencies (tested in Ubuntu)

• PALISADE: a lattice-based homomorphic encryption library in C++. Follow the instructions on https://gitlab.com/palisade/palisade-release to download, compile, and install the library. Make sure to run make install in the user-created \build directory for a complete installation.

• Crypto++: a Linux cryptographic library to provide various functionality (we primarily utilize this for our Pailler implementation). Follow the instructions https://github.com/weidai11/cryptopp and make sure to run make install in the root dir. of the library for a complete install.

• pybind-11: pip install pybind11, make sure to have have python3 and cmake already installed.

palisade_pybind folder contains the implementation of weighted average operation with python bindings.

To Run

go to the palisade_pybind/SHELFI_FHE/src folder and run pip install ../

Tests/Examples as wella as the pybind11 binding code are located in the ../pythonApi directory (relative to dir. above) and can be run by simply running:

python3 ../pythonApi/[example].py
