A Comparison of PIV, PIV-I and CIV Credentials
Publication Date: February 2012
Homeland Security Presidential Directive 12 (HSPD-12) mandates a standard for a secure and reliable form of identification to be used by all Federal employees and contractors. Signed by President George W. Bush in August 2004, HSPD-12 initiated the development of a set of technical standards and issuance policies (Federal Information Processing Standard 201 [FIPS 201]) that create the Federal infrastructure required to deploy and support an identity credential that can be used and trusted across all Federal agencies for physical and logical access.
The policy, processes and technology in FIPS 201 also reflect specifications defined in a number of other special publications (SPs) specifically written for FIPS 201 and build on other National Institute of Standards and Technology (NIST) standards and SPs that support best practices. Importantly these standards also build on international and national standards from organizations such as the Internet Engineering Task Force (IETF), the International Telecommunications Union (ITU), the Institute of Electrical and Electronics Engineers (IEEE), the International Organization for Standardization (ISO), the Organization for the Advancement of Structured Information Standards (OASIS) and others.
Two additional credentials have been defined–the Personal Identity Verification-Interoperable (PIV-I) and Commercial Identity Verification (CIV) credentials–with the goal of taking advantage of the infrastructure created by the Federal government’s PIV program. The policy, process and technology applied to each of these credentials result in a level of assurance and interoperability, and ultimately the extent to which it can be used and trusted in its intended application. As shown in the table below, the policy and process around PIV and PIV-I enable the interoperability and trust of the credential. The CIV credential definition was developed to define a commercial credential that could take advantage of the PIV infrastructure. Identity and credential infrastructure requires an additional investment in order to adhere to and maintain these policies and processes. In return, users and organizations can access identity and credential services in the commercial arena with many of the advantages enabled by the creation of the PIV infrastructure.

 X.509 Certificate Policy for the Federal Bridge Certification Authority, version 2.25, Federal Bridge Certification Authority, December 9, 2011
 The FASC-N contains a federal agency code which is managed by NIST. PIV-I and CIV credential numbers (UUIDs) are generated by the issuing organization. See NIST SP 800-87 for additional information.
 The Smart Card Alliance Access Control Council selected the name CIV and documented the specifications that would define a credential that was technically compatible with the PIV specifications.

About the Access Control Council
The Smart Card Alliance Access Control Council is focused on accelerating the widespread acceptance, use, and application of smart card technology for physical and logical access control. The group brings together, in an open forum, leading users and technologists from both the public and private sectors and works on activities that are important to the access control community and that will help expand smart card technology adoption in this important market.
