NIST PQC FIPS 203/204/205 — Community Deep Dive & Analysis Thread
The long-awaited NIST PQC standards are finalized. Compiling community analysis, implementation notes, and deployment challenges for ML-KEM, ML-DSA, and SLH-DSA. Open for structured critique and benchmarks.
QB
The tightness gap in the QROM reduction for ML-DSA is still an open problem. Table 2 in the spec acknowledges this but doesn't provide a concrete bound. Anyone working on this?
PW
For embedded deployments, ML-KEM-512 key generation is ~300µs on Cortex-M4. That's workable for most IoT scenarios. Sharing our benchmark repo shortly.

Novel Trapdoor Construction for NTRU over Cyclotomic Fields — Peer Review Request
New trapdoor sampling algorithm improving on GPV, reducing Gram-Schmidt norms in ring variants. Draft on arXiv:2501.xxxxx. Seeking critique on Lemma 3 and reduction tightness.
DL
Lemma 3 looks solid but the bound in eq. (7) is loose by a factor of √n. Have you tried the hybrid argument from Micciancio-Peikert?

"Harvest Now, Decrypt Later" — How Long Do We Really Have Before Q-Day?
NSA, CISA, BSI estimates diverge. Some say 8-10 years, others 15+. Given recent advances (Microsoft topological qubits, Google Willow), how should organizations prioritize PQC migration?

Why Post-Quantum Cryptography is the Enterprise Priority for 2026 — A Lahara Perspective
With NIST FIPS 203/204/205 now finalised, the window for proactive PQC migration is narrowing. Our CTO breaks down what organisations must do in the next 12 months to avoid harvest-now-decrypt-later exposure.
