NIST IR 8547 primer
NIST IR 8547 provides transition guidance for migrating to FIPS 203/204/205 — target 2030 for most organizations.
Framework
Transitioning to post-quantum cryptography standards
Deadline: 2030
Executive summary
NIST Interagency Report 8547 provides transition guidance for migrating from quantum-vulnerable cryptography to FIPS 203/204/205. Most organizations target 2030 for substantial transition progress — aligned with CNSA 2.0 tiers and industry planning signals including Google and Cloudflare's 2029 internal targets.
Transition categories
NIST organizes migration into categories by algorithm type and usage context — key establishment, digital signatures, hash functions. Your inventory must tag findings into these categories for prioritization.
Deprecation timeline awareness
Plan for deprecation of RSA, ECDSA, and finite-field DH in favor of ML-KEM and ML-DSA. ECC may require attention on accelerated timelines per recent research — do not assume RSA always migrates first.
Evidence for regulated orgs
- Algorithm-level inventory mapped to IR 8547 categories
- CBOM for GRC integration
- Signed reports with verify links
- Monitor drift between assessment cycles
Qtangl mapping
Scan exports include NIST IR 8547 crosswalk in compliance pack. Readiness score incorporates deadline pressure from IR 8547 tiers.
