Helbench

Benchmark framework for Fully Homomorphic Encryption (FHE) libraries. Compare SEAL, OpenFHE, and HElib on BFV, BGV, and CKKS schemes with consistent parameters.

Quick Start

git clone --recurse-submodules https://github.com/afDursun/HelBench
cd helbench

pip install -r requirements.txt

cd external/SEAL && cmake -B build -DCMAKE_BUILD_TYPE=Release && cmake --build build && cd ../..
cd external/OpenFHE && cmake -B build -DCMAKE_BUILD_TYPE=Release && cmake --build build && cd ../..

./run_all.sh

Results: results/raw/, results/summary/, results/figures/

Requirements

• C++17, CMake 3.13+
• Python 3 (pandas, matplotlib, numpy)
• HElib: system install (find_package(helib))

Usage

Command	Description
./run_all.sh or make all	Full pipeline: benchmarks + analysis + figures
make benchmark	Run benchmarks only
make analyze	Statistical analysis (requires existing CSV)
make figures	Generate figures only

Project Layout

Path	Description
common/params.json	Single config source; edit here to change parameters
benchmarks/{seal,openfhe,helib}/	Per-library benchmarks
scripts/	Python: params generation, analysis, visualization
results/raw/	Raw CSV outputs
results/summary/	Aggregated tables
results/figures/	Plots

Configuration

Edit common/params.json for degrees (N), repeats, plain modulus, etc. The C++ side uses params.h, generated from params.json when you run benchmarks.
