HElib
An open-source C++ library implementing homomorphic encryption with BGV and CKKS schemes, optimized for efficient evaluation.
What is HElib?
HElib is an open-source C++ library that implements homomorphic encryption, allowing computations to be performed directly on encrypted data without needing to decrypt it first. It supports both the BGV scheme with bootstrapping and the CKKS approximate number scheme, providing tools for secure, privacy-preserving data processing. The library focuses on efficient evaluation through optimizations like ciphertext packing and automatic noise management.
Cryptography researchers, privacy engineers, and developers working on secure computation applications who need to implement homomorphic encryption in their systems.
HElib offers a comprehensive, production-ready implementation of advanced homomorphic encryption schemes with extensive optimizations for performance. Its "assembly language for HE" approach provides both low-level control and high-level abstractions, making it suitable for both research experimentation and building practical encrypted computation applications.
Overview
HElib is an open-source software library that implements homomorphic encryption. It supports the BGV scheme with bootstrapping and the Approximate Number CKKS scheme. HElib also includes optimizations for efficient homomorphic evaluation, focusing on effective use of ciphertext packing techniques and on the Gentry-Halevi-Smart optimizations.
