Encrypted compute at hardware speed.

Hovera designs FPGA accelerators for fully homomorphic encryption and zero-knowledge proof systems. It is the arithmetic that makes computing on data you never decrypt possible.

01 — What we build

We accelerate the arithmetical building blocks in confidential computing.

01

Polynomial arithmetic cores

  • Residue number systems
  • Parameterised moduli and degrees
  • RLWE-based schemes

02

Proof-system engines

  • MSM and curve arithmetic
  • Witness streaming
  • Prover-side throughput

03

Memory-bound dataflow

  • HBM-attached pipelines
  • On-chip data reuse
  • Latency hiding

04

Host integration

  • Library-level interfaces to OpenFHE
  • Full abstraction of Host to FPGA communication
  • Runtime and scheduling

02 — Where it matters

The workloads that only become viable once the maths is fast.

Confidential inference

Running a model over data the model owner never sees, and the data owner never hands over in the clear.

Regulated data collaboration

Joint analytics across institutions — health, finance, public sector — without pooling raw records anywhere.

Verifiable computation

Proof generation for rollups, bridges and audit trails, where prover throughput sets the cost of the whole system.

Post-quantum primitives

The same lattice arithmetic underpins PQC, so the hardware carries over to schemes now entering deployment.

03 — Team

Our team brings together expertise in cryptographic research, hardware design, software integration, and DevOps to turn encrypted computation research into deployable systems.

04 — Contact

Have a workload that encryption made too slow?

We are interested in concrete problems: a scheme, a parameter set, a latency or throughput target you cannot reach today. Research collaborations and student projects are welcome too.
