A procurement workflow for checking whether a supplier crypto claim is supported by the right FIPS evidence: CAVP algorithm testing, CMVP module validation, tested environment, Security Policy scope, and approved-mode operation.
Use it to turn vague "FIPS compliant" claims into certificate numbers, boundaries, configurations, change triggers, and retention records backed by NIST sources.

Classify the supplier's claim before accepting any certificate. FIPS 140-3 applies to U.S. federal agencies that use cryptography-based security systems to protect sensitive information and shall be used in designing and implementing cryptographic modules that federal departments and agencies operate or that are operated for them under contract; other buyers may require it by contract or adopt it voluntarily. A Cryptographic Algorithm Validation Program () entry covers a named algorithm implementation and . A Cryptographic Module Validation Program () certificate covers a named cryptographic module, version, boundary, tested environment, public , and validation status. The deployed service must also follow the approved-service and configuration conditions in that Security Policy. If the supplier provides only "FIPS compliant" marketing copy, record the claim as unsupported until the public evidence matches the delivered configuration.
Separate four claims before reviewing any certificate. An approved algorithm standard such as AES or SHA is not the same thing as a -tested implementation. A CAVP algorithm certificate is not the same thing as a module certificate. A CMVP certificate still has a boundary, version, tested operating environment, approved services, and usage conditions. Procurement wording should mirror that exact scope.
Procurement owns the supplier request and contract record; product security matches certificates and the ; engineering and operations confirm the delivered binary, hardware path, configuration, and service indicator. Ask the supplier to identify the component that performs each cryptographic operation, then request the evidence needed for that claim. An algorithm-only claim needs the public record and its implementation details. A module claim also needs the public record and Security Policy. An approved-service claim needs the service indicator, configuration, and usage conditions that apply to the deployed service.
A useful procurement package asks for the evidence a reviewer can tie to a shipped configuration. The IG states that algorithm validation certificates identify the validated algorithm implementation and tested operating environment, while module validation certificates identify the validated module and tested operating environment. That distinction should drive the intake form and the contract exhibit.
For software, firmware, and hybrid modules, pay close attention to operating environments. When a -validated algorithm implementation is bound into a module undergoing FIPS 140-3 testing, the guidance requires the CAVP-tested environment to be identical to, or fully included in, the module's test environment under stated rules. Procurement should capture CPU or processor, operating system, firmware, accelerator path, and deployment profile when those facts determine whether the delivered configuration matches the public evidence.
This workflow helps convert supplier "FIPS compliant" statements into certificate checks, Security Policy constraints, approved-mode controls, and change-review tasks.

Use cited NIST source material to resolve CAVP, CMVP, operating-environment, and approved-mode questions before acceptance.

Use evidence to show that a named algorithm implementation was successfully tested and added to a NIST validation list. Use evidence to show that a named cryptographic module was validated against FIPS 140-3. A product can include a validated algorithm without the product or its full cryptographic boundary being a validated module. A validated module can also have usage limits that procurement and deployment teams must preserve.
The review output should avoid broad labels. Say "uses AES implementation covered by certificate X in operating environment Y" or "uses cryptographic module Z validated under certificate N when configured according to S," rather than converting either certificate into a blanket product approval. If only part of a product falls inside the validated boundary, name the excluded components and do not extend the claim to them.
is a service-use and configuration question, not a certificate label for the whole product. guidance defines it as a set of services that includes at least one service using an approved security function or process and excludes non-approved security functions or processes. The guidance separately allows some non-approved algorithms to run with no security claimed under strict conditions; that allowance does not make them approved security functions.
Use the public to identify approved security services, non-approved services, algorithm certificates, roles, interfaces, operating rules, service indicators, and caveats. Ask how the deployed service reports approved use, because FIPS 140-3 guidance focuses on an indicator for the approved security service and does not always accept a single global mode indicator.
A delivered-configuration change reopens the evidence decision without automatically revoking every certificate. guidance includes cases where version changes, excluded-component changes, operating-environment changes, processor acceleration, or embedded modules require validation or revalidation analysis. Record the specific change, compare it with the certificate and , and seek supplier, laboratory, or CMVP clarification when the applicable scenario is unclear.
Retain the evidence in a way that lets future auditors reconstruct the accepted claim. Store the public source URL, certificate identifier, version, supplier attestation, product version, operating environment, reviewer decision, conditions, exception owner and expiry, and rejection notes together. When a supplier ships a cryptographic update, rerun the review rather than copying the previous acceptance forward.
Keep this operating table in intake notes or contract review. Each row should produce an evidence-backed decision that another reviewer can reconstruct.
1 | Claim intake | Procurement and security | Supplier FIPS claim, product/version, crypto component inventory | Is this an algorithm claim, module-validation claim, approved-mode claim, or internal target?
2 | Certificate match | Security reviewer | / certificate IDs, implementation names, module names, versions, tested operating environments | Does the public evidence match the delivered configuration?
3 | review | Product security and operations | Security Policy, approved services, service indicators, caveats, operator guidance | Can the deployment operate inside the validated boundary and approved-mode conditions?
4 | Decision and change control | Procurement, engineering, supplier owner | Acceptance statement, gaps, supplier notice clause, release record, rejected-evidence log, reassessment triggers | Is the evidence accepted, conditionally accepted, escalated, or rejected, and what changes reopen it?
