OpenFHE is an open-source fully homomorphic encryption software library that provides implementations of various FHE schemes, including Brakerski/Fan-Vercauteren, Brakerski-Gentry-Vaikuntanathan, Cheon-Kim-Kim-Song, and Ducas-Micciancio, supporting both integer and real-number arithmetic. The library offers advanced features such as post-quantum security, bootstrapping, scheme switching, and hardware acceleration through a standard Hardware Abstraction Layer. OpenFHE includes multiparty extensions, threshold FHE, and proxy re-encryption capabilities, enabling secure collaborative data processing. Its design aims to simplify the integration of FHE into applications through transpilers and compilers, allowing developers to build FHE-enabled solutions without deep cryptographic expertise. The library is designed to accelerate the adoption of privacy-preserving technologies and support secure computation on encrypted data across industries.
