FHERMA

Fully Homomorphic Encryption (FHE) enables computation over encrypted data and is considered a fundamental tool for privacy-preserving systems. Despite significant theoretical progress, its practical adoption remains limited. One contributing factor is the absence of reusable, application-level components suitable for integration into real-world systems. This work introduces a library of FHE components developed through a competition-based framework. The components are outcomes of a series of formalized challenges published on the FHERMA platform, each targeting a specific challenge—such as comparison, sorting, or matrix operations—under concrete cryptographic and performance constraints. This initial release includes contributions from independent researchers and reflects a variety of approaches across different FHE schemes. The library is intended to expand over time as new challenges are introduced and solved, forming a foundation for building and evaluating privacy-preserving applications.
