Why we cannot wait for better post-quantum signature algorithms

NIST is advancing nine new post-quantum signature algorithms as potential candidates for future standardization. We take a closer look at all of them, and argue that while they are in the works and show great potential, we should use ML-DSA for now — the best one currently available.

Why this matters
Why now

The NIST standardization process for post-quantum cryptographic algorithms is advancing, necessitating a strategic decision on which algorithms to adopt for future security.

Why it’s important

The transition to post-quantum cryptography is critical for protecting current and future digital communications and infrastructure against quantum computer attacks, creating a race for adoption of new protocols.

What changes

The recommendation to prioritize ML-DSA over other developing post-quantum signature algorithms for immediate implementation changes the strategic focus for securing digital systems.

Direct

Immediate efforts will focus on integrating ML-DSA into existing security protocols and systems.

Second

Accelerated adoption of ML-DSA could create a de facto standard before all NIST candidates are fully evaluated.

Third

This could lead to a 'first-mover advantage' in quantum-resistant security, potentially influencing global digital trust frameworks.
