- CUDA >= 11.0
- CMake >= 3.20
- GCC >= 11.0
CMAKE_CUDA_ARCHITECTURES: Set the CUDA architectures to compile for. For example, A100 uses80, V100 uses70, and P100 uses60.
- Native GPU acceleration (for NVIDIA GPUs)
- Support word-wise schemes including BGV, BFV, and CKKS (without bootstrapping)
- SOTA performance in most operations
- Easy to integrate with applications (PPML, etc.)
- Use git to clone this repository recursively (including submodules)
- Use CMake to configure and build this library
- Look into build/bin and execute binaries
- (Optional) Use python bindings (See
python/directory for details)

We are planning to support the following features in the future:
- [] support bit-wise schemes TFHE/FHEW
- [] support scheme switching between word-wise schemes and bit-wise schemes
- [] support bootstrapping for BFV/BGV/CKKS
