Poulpy v0.1 🐙

We’re releasing v0.1 of Poulpy, an Apache-2.0 open-source, fast and modular Rust library for fully homomorphic encryption (FHE) over the Torus.

Poulpy is the first library to adopt bivariate polynomials to represent Torus polynomials, providing a common plaintext space across all FHE schemes.

Built from the ground up to be backend-agnostic, Poulpy allows users to design FHE circuits and implement lattice-based cryptography in a way that is fully generic over the hardware backend. This design makes it possible to switch between backends seamlessly at compile time.

To further support extensibility, Poulpy defines a clear Hardware Abstraction Layer (HAL), making the addition of new hardware backends both straightforward and efficient.

Call for action

• For application developers: We invite you to try Poulpy on your use cases, put it through stress tests, and share your feedback. We take feedbacks seriously and will use them continuously improve the library.
• For researchers: If you’d like to implement your ideas using Poulpy or simply use it to concretise research work, we’d love to hear from you. Our goal is to ensure that Poulpy is also a strong and intuitive platform for prototyping.
• For hardware developers: If you’re building FHE accelerators on specialized hardware (GPU, FPGA, ASIC, etc.), let’s connect. We are committed to making Poulpy’s HAL and low-level layouts as well-defined as possible so that integrating new backends is seamless.
