HEU (Homomorphic Encryption processing Unit) is a user-friendly and high-performance homomorphic encryption library that supports multiple types and scalable hardware acceleration.
https://www.secretflow.org.cn/docs/heu/
Homomorphic encryption algorithms are mainly divided into two categories: partially homomorphic encryption (PHE) and fully homomorphic encryption (FHE). Currently, HEU supports most PHE algorithms, while FHE is still under development and will take some time.
Supported algorithms:
- Additive homomorphic encryption
- Paillier (recommended)
- Okamoto–Uchiyama (recommended)
- EC ElGamal
- Damgard-Jurik
- Damgard-Geisler-Krøigaard (DGK)
- Fully homomorphic encryption
- Under development and is the current focus of work.
Each algorithm includes a variety of different implementations, and some implementations support hardware accelerators. For more details, please refer to the Document

pip install sf-heuThe following command will automatically compile and install HEU into the default Python environment:
git clone [email protected]:secretflow/heu.git
cd heu
sh build_wheel_entrypoint.sh
# just compile, do not run any UT (optional)
bazel build heu/...
# compile and run all UTs
bazel test heu/...SecretFlow is an open and inclusive community, and we welcome any kind of contribution. If you want to improve HEU, please refer to Contribution Guide
