PQShield

Provides cryptographic building blocks that developers integrate into applications and devices to prepare for quantum-computer attacks. PQC runs on conventional computing hardware and does not require a quantum network.

Product scope
Post-quantum and hybrid cryptographic software libraries for classical systems, within a broader cryptography product portfolio.

A company profile may discuss several systems. Capabilities remain attached to the product and conditions named in each source; they do not transfer automatically to related organizations. A verified security relationship has not been attached to this record.

TECHNOLOGY & ACCESS

What it does. Where it fits.

Post-quantum and hybrid cryptographic software libraries for classical systems, within a broader cryptography product portfolio.

Who should look closer

Software and embedded-system teams that need supported cryptographic primitives and a version-specific assurance path.

QubitWire’s editorial assessment of practical fit.

Library evaluation

PQCryptoLib-Core offers an evaluation request, documented APIs and integration assistance; verify the selected product version and its validation scope.

DOCUMENTED EVIDENCE

What the sources establish

NIST certificate 4800 validates PQCryptoLib 1.0.0 at FIPS 140-3 Level 1 on specified configurations under an interim validation. Microchip separately documents PQShield library training within its FPGA developer ecosystem.

csrc.nist.gov ↗microchip.com ↗

What remains unresolved

Certificate 4800 does not validate every PQShield version or all PQC algorithms; its approved-algorithm list does not include ML-KEM or ML-DSA. Algorithm testing, module validation and complete deployment security are separate questions.

The next question to watch

Does the exact library version, algorithm set and target platform meet the customer's required validation and side-channel assurance scope?

A research question, not a promised milestone.

QubitWire coverage

Open research questions

Editorial questions for this profile. No reviewed closure decision has been recorded; unanswered questions do not lower the official score.

Open research question

Does the exact library version, algorithm set and target platform meet the customer's required validation and side-channel assurance scope?

What evidence would help

A source addressing this question must identify the named system, experiment or deployment, its conditions, measured outcome and remaining limitations. Is a claim about standards alignment, validation or a completed certification?

What would resolve it?

An editorial review must explain which part of this question the evidence resolves. A roadmap or an announcement alone does not close it.

No resolved, partial or disputed outcome is asserted without a reviewed transition and its evidence.

Suggest evidence
Open research question

Which named system or service can I use under the documented access route?

What evidence would help

Check the current terms for library evaluation. Identify the system version, eligibility, restrictions and whether the result used hardware or simulation.

What would resolve it?

Current primary documentation must identify the offering, eligible user and access conditions. An unspecified company-level access claim is insufficient.

No resolved, partial or disputed outcome is asserted without a reviewed transition and its evidence.

Suggest evidence
Open research question

Which exact algorithm, implementation and version is supported?

What evidence would help

Provide the source location, relevant product or generation, workload, resource constraints and reported uncertainty. Keep measurements, simulations and announced targets distinct.

What would resolve it?

A source reviewer must map the evidence to this exact scope. Missing disclosure remains unknown; it is not technical failure.

No resolved, partial or disputed outcome is asserted without a reviewed transition and its evidence.
