Personal Identity Verification (PIV) Interfaces, Cryptographic Algorithms, and Key Sizes: Drafts of SP 800-73-5 and SP 800-78-5 Available for Public Comment

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:


Removal of the previously deprecated CHUID authentication mechanism
Deprecation of the SYM-CAK and VIS authentication mechanisms
Addition of an optional 1-factor secure messaging authentication mechanism (SM-Auth) for contactless interfaces for facility access applications
Additional use of the facial image biometric for general authentication via BIO and BIO-A authentication mechanisms
Restriction on the number of consecutive activation retries for each of the activation methods (i.e., PIN and OCC attempts) to be 10 or less
SP 800-73-5: Part 3 on PIV Middleware specification marked as optional to implement

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:
