Paper on qFALL Released: Bridging the Theory-to-Practice Gap
We are happy to announce the release of our paper “qFALL – Rapid Prototyping of Lattice-based Cryptography” on IACR ePrint (2026/069). The paper details the architectural decisions and design principles that enable efficient, auditable prototyping, as well as performance benchmarks of qFALL.
We are pleased to announce that our paper, qFALL – Rapid Prototyping of Lattice-based Cryptography, is now available on the IACR ePrint archive: https://ia.cr/2026/069.
The paper describes how qFALL bridges the gap between theoretical specification and optimized implementation. In this work, we explain how the library suite enables the rapid assembly of minimal working prototypes, which can then be incrementally optimized by replacing performance bottlenecks with specialized modules.
This assembly process is supported by the library suite’s modular structure and the intuitive discovery of descriptively named features. Due to this descriptive, theory-affine notation, prototypes become easily auditable, modifiable, and extensible. As a result, these prototypes turn into reusable resources to the scientific community.
Beyond the project’s architecture, the paper provides a brief overview of the implemented functions and the underlying infrastructure of qFALL. It highlights exceptional features – such as seamless type interoperability (e.g., between integers \(\mathbb{Z}\) and rationals \(\mathbb{Q}\)) – and presents design principles and performance benchmarks.
The paper serves as a theoretical companion to the codebase and tutorial.
