 **Poulpy** is a fast & modular FHE library that implements Ring-Learning-With-Errors based homomorphic encryption. It adopts the bivariate polynomial representation proposed in [Revisiting Key Decomposition Techniques for FHE: Simpler, Faster and More Generic](https://eprint.iacr.org/2023/771). In addition to simpler and more efficient arithmetic than the residue number system (RNS), this representation provides a common plaintext space for all schemes and allows easy switching between any two schemes. Poulpy also decouples the schemes implementations from the polynomial arithmetic backend by being built around a hardware abstraction layer (HAL). This enables user to easily provide or use a custom backend.
