FHERMA is the premier platform for FHE benchmarking, challenges, and ecosystem development. We provide standardized benchmarks, real-world challenges, and a community-driven approach to advancing fully homomorphic encryption technology.

The FHERMA Approach

Community-driven and challenge-based development of FHE components through structured, merit-based challenges and transparent benchmarking.

How It Works

1

FHERMA publishes challenges

Well-defined challenges like "efficient encrypted matrix multiplication"

2

Participants submit solutions

Automatically evaluated for correctness, security, and performance

3

Top solutions integrated

Released under Apache 2.0 license and integrated into Polycircuit

Challenge Types

Black-box Challenges

Only encrypted outputs are submitted, preserving implementation confidentiality

Privacy-focused evaluation

White-box Challenges

Full source code submitted for benchmarking and deeper analysis

Open-source collaboration

Why This Model Is Effective

Efficiency

Broad range of strategies explored, often surpassing compiler-generated solutions

Openness

All contributions released under permissive licensing

Ecosystem

Welcomes both experts and new contributors

Scalability

Supports multiple FHE schemes and grows with new techniques

FHERMA Cookbook
