ComputeFHE

ComputeFHE is a C++ project for arithmetic operations over Fully Homomorphic Encryption over Torus (TFHE) using the OpenFHE library based on algorithms proposed in:

Taşel, F.S., Saran, A.N. Improved arithmetic efficiency in TFHE through gate-level optimizations. J Supercomput 81, 1633 (2025). https://doi.org/10.1007/s11227-025-08107-8

It provides implementations of standard and optimized arithmetic operators and gate logic operations on encrypted data.

Please cite the paper if you use ComputeFHE in your research.

Features

• Homomorphic arithmetic and logic gate implementations
• Optimized variants for faster computation
• Clean CMake-based build system

Requirements

• C++17 compiler (e.g., g++ >= 9 or clang >= 10)
• CMake >= 3.14
• OpenFHE library (installed on your system)

Building

1. Clone this repository:

   git clone https://github.com/fstasel/compute-fhe.git
   cd compute-fhe

2. Make sure you have OpenFHE installed. If not:

   git clone https://github.com/openfheorg/openfhe-development.git
   cd openfhe-development
   mkdir build && cd build
   cmake .. -DCMAKE_INSTALL_PREFIX=/usr/local
   make -j$(nproc)
   sudo make install

3. Build ComputeFHE:

   cd compute-fhe
   mkdir build && cd build
   cmake ..
   make -j$(nproc)

4. Run the program:

   ./compute-fhe
