Chain Reaction Researchers Publish New Work on Distributed Polynomial Generation for FHE Hardware Acceleration

Chain Reaction researchers Ilan Rosenfeld, Noam Kleinburd, Hillel Chapman, and Dror Reuven have published a new paper addressing a core architectural challenge in Fully Homomorphic Encryption (FHE) hardware acceleration: the generation of uniformly sampled polynomials.

Polynomial generation is a fundamental building block in many FHE schemes. In hardware implementations, however, it introduces significant constraints. Traditional approaches often rely on serial processes and dense wiring, which increase routing complexity, limit parallelism, and raise overall implementation cost.

The team proposes a distributed method for generating uniformly sampled polynomials that reduces wiring requirements and enables random access. By removing traditional serial bottlenecks, the approach supports more scalable and hardware-friendly architectures.

This work provides concrete design direction for implementing FHE in dedicated accelerators. It addresses practical constraints at the hardware level while maintaining the mathematical properties required by the cryptographic scheme.

The paper marks another step in Chain Reaction’s effort to build efficient and scalable FHE hardware acceleration.
