In January 2022, NIST revised Federal Information Processing Standard (FIPS) 201, which establishes standards for the use of Personal Identity Verification (PIV) Credentials – including the credentials on PIV Cards. NIST Special Publication (SP) 800-73-5: Parts 1–3 and SP 800-78-5 have subsequently been revised to align with FIPS 201 and are now available for public comment.
SP 800-73-5: Parts 1–3 ipd (Initial Public Draft)
SP 800-73-5: Parts 1–3 ipd, Interfaces for Personal Identity Verification, describes the technical specifications for using the PIV cards including a PIV data model (Part 1), card edge interface (Part 2), and application programming interface (Part 3). Major changes to the documents include:
SP 800-78-5 ipd
SP 800-78-5 ipd, Cryptographic Algorithms and Key Sizes for Personal Identity Verification, defines the requirements for cryptographic capability of the PIV Card and supporting systems in coordination with FIPS 201-3. It been modified to add additional algorithm and key size requirements and to update the requirements for Cryptographic Algorithm Validation Program (CAVP) validation testing including:
NIST specifically seeks input from federal agencies on the suitability of the digital signature algorithms and key sizes specified in SP 800-78-5. The draft revisions accommodate RSA signatures with 2048-bit and 3072-bit keys, and ECDSA signatures with the P-256 and P-384 curves, for authentication services. NIST requests feedback on the potential need to support RSA with 4096-bit keys, or for the need to add support for the EdDSA signature algorithm that is now specified in FIPS 186-5.
The comment period for these drafts is open through December 8, 2023
November 15, 2023. See the publication details (linked above) to download the drafts and comment templates. Comments and inquiries should be sent to firstname.lastname@example.org.
WorkshopNIST hosted a Personal Identity Verification Webinar on November 8, 2023, to discuss both SP 800-73-5 ipd and SP 800-78-5 ipd.
