Secure Smart Cards: Check the Evidence Behind Security Claims - Yenra

Translate a claim into something checkable

On a small screen, scroll sideways to read all columns.

Record the claim literally, then identify the evidence needed to accept it. “Uses encryption” is a capability description. The operational question is which keys and protocol protect which exchange, who verifies the result and what happens when a credential is lost or revoked.

Follow a FIPS claim to the official record

For a FIPS cryptographic-module claim, use the NIST CMVP validated-module search. Match the vendor, module, certificate and listed versions. Read the security policy and the certificate’s current status and caveats. Save the lookup date and the exact record used.

NIST’s CMVP process guidance explains that validation applies to the identified module, version and environment. A product containing that module still needs evidence that it uses the validated configuration correctly. Module validation alone leaves the reader, issuer, backend and access-control policy to be assessed.

Keep certificate status separate from your organization’s acceptance policy. Have the responsible security reviewer decide whether the documented status and configuration satisfy the actual requirement. For formal security-policy content, consult NIST’s CMVP security-policy requirements and the policy attached to the module record.

Resolve a version mismatch before accepting the claim

Do not retain vulnerable software merely to preserve a certificate match. NIST’s CMVP guidance recommends security patching through the organization’s vulnerability and risk-management process while vendors pursue appropriate revalidation. Record the patch decision, resulting configuration and evidence status together.

Review the credential system around the card

Draw the path from enrollment to issuance, normal use, revocation and replacement. For each step identify the person or system authorized to act and the evidence it creates. Ask who controls personalization keys, how readers receive trusted configuration and how backend authorization changes reach deployed equipment.

Test the actual user and administrative workflows with authorized test credentials. Include a revoked card, an expired entitlement, an unavailable backend where relevant and a replacement card. Confirm that logs identify the event without exposing secrets. Keep keys, PINs and live credential material out of the downloadable review worksheet.

• Record the claimed threat model and the limits of each evaluation.
• Match delivered versions and options to the approved design.
• Identify privileged administration and issuer responsibilities.
• Verify revocation, replacement and incident-response ownership.
• Document which decisions need specialist review and how exceptions are approved.

Keep the evidence current with the system

The completed review should say which claim is supported, by which record, for which delivered configuration, and which questions remain open. Attach relevant certificates and policies through your controlled evidence repository, respecting access requirements.

Reopen the review after a firmware change, card substitution, reader migration, key-management change or relevant certificate-status update. A security claim stays meaningful through configuration control and operational follow-through. The worksheet helps preserve that chain of evidence; it does not issue a certification or determine compliance for a particular organization.

Keep a working record

Download the editable working record (plain text). It includes purpose, instructions, evidence fields and this guide's source links. Save a separate copy for each evaluation and record unresolved issues with their owner.
