Crypto-agile today, post-quantum ready tomorrow.
B5 Secure’s cryptographic posture is built for migration: the signing and key-establishment contract stays constant while the primitives move to NIST’s finalized post-quantum standards. This page documents the FIPS 140-3 foundation today and the ML-KEM / ML-DSA migration posture toward CNSA 2.0 timelines.
Harvest-now, decrypt-later makes this a present-tense attestation.
Long-lived financial and identity data captured today can be exposed once cryptographically relevant quantum computers arrive. NIST has finalized ML-KEM (FIPS 203) and ML-DSA (FIPS 204), and CNSA 2.0 sets migration timelines. The relevant question for a reviewer is whether a platform’s cryptography is agile enough to migrate without a rebuild. B5’s is, and this page documents the posture.
The posture, stated precisely.
Led by the outcome — provable, future-proof enforcement — with cryptography described accurately, not overclaimed.
FIPS 140-3 Level 3 foundation
Signing keys live in a single-tenant Azure Managed HSM validated to FIPS 140-3 Level 3, with attestation proving provenance inside the hardware boundary — today.
Crypto-agile by design
Signing primitives are configurable, so moving to post-quantum signing is a configuration change while the authorization contract at the call site is unchanged.
ML-KEM and ML-DSA
Alignment to NIST’s finalized standards — ML-KEM (FIPS 203) for key establishment and ML-DSA (FIPS 204) for signatures.
CNSA 2.0-aligned timeline
A documented migration posture aligned to CNSA 2.0, so the transition is planned rather than reactive.
Confidential computing options
Customer-managed keys at rest, TLS 1.3 in transit, and confidential-computing options (AMD SEV-SNP, Intel TDX) for the most sensitive operations.
Standards-grounded references
Grounded in NIST SP 800-57 key-management guidance and the FIPS 203/204 suite, not marketing claims.
How reviewers use this.
Defend long-lived data
Data protected today stays defensible as primitives migrate, with no change to the enforcement model.
Migration as configuration
Crypto-agility means the post-quantum transition is not a multi-quarter re-architecture.
Validated foundation
The FIPS 140-3 Level 3 HSM is validated today; the PQ migration is a documented, standards-aligned posture.
Precise about cryptography — no overclaiming.
What the primitives do, stated correctly.
To be precise: authentication mechanisms prove identity and integrity; they are not, by themselves, encryption. B5’s post-quantum posture concerns the agility to migrate signing and key-establishment primitives to the NIST-finalized standards. The HSM and FIPS 140-3 foundation is validated today; the ML-KEM / ML-DSA migration is a documented, standards-aligned posture, not a present claim of completed migration.
Post-quantum readiness, documented and precise.
