As we stand on the brink of the quantum computing era, the need for quantum-resistant cryptographic tools is more pressing than ever. Today, we're proud to introduce the open sourcing of btq-falcon-js, our customized JavaScript implementation of the NIST-approved FALCON signature scheme. 

What is FALCON?

FALCON (Fast-Fourier Lattice-based Compact Signatures over NTRU) stands at the cutting edge of cryptographic innovation, securing a prestigious spot in the National Institute of Standards and Technology (NIST)'s fourth round of the post-quantum cryptography standardization process. This recognition underscores FALCON's potential to withstand the sophisticated challenges quantum computing poses to current cryptographic standards. Designed for both efficiency and security, FALCON offers a quantum-resistant safeguard, ensuring the integrity of digital signatures in an era beyond classical computing threats.

Enhancements in BTQ-Falcon

Our journey in enhancing FALCON's capabilities, leading to the development of btq-falcon-js, is built upon the shoulders of giants. We extend our gratitude to the architects of the original FALCON algorithm for their groundbreaking work and to Grammatopoulos Athanasios-Vasileios for the Emscripten compiler setup, which facilitated the adaptation of FALCON into a JavaScript environment.

In our quest to push the boundaries of digital security, we've tailored the original FALCON algorithm into btq-falcon-js, introducing several key enhancements that bolster its performance and applicability. Our version stays true to FALCON's core principles while elevating its deterministic nature, a critical factor for its integration with PQScale, our aggregate signature solution. The key enhancements include:

• Deterministic Output: By refining the algorithm's output, we've minimized the variability in signature generation. This deterministic nature is crucial for applications requiring consistent and predictable cryptographic operations, enhancing both security and efficiency.
• Integration Readiness: btq-falcon-js is engineered for seamless integration with PQScale, facilitating a straightforward process for developers to incorporate quantum-resistant signatures into their existing systems without extensive modifications.
