public key infrastructure (PKI)

Abbreviation(s) and Synonym(s):

PKI

Definition(s):

  A support service to the PIV system that provides the cryptographic keys needed to perform digital signature-based identity verification and to protect communications and storage of sensitive verification system data within identity cards and the verification system.
Source(s):
FIPS 201 under Public Key Infrastructure (PKI) [Withdrawn]

  The framework and services that provide for the generation, production, distribution, control, accounting, and destruction of public key certificates. Components include the personnel, policies, processes, server platforms, software, and workstations used for the purpose of administering certificates and public-private key pairs, including the ability to issue, maintain, recover, and revoke public key certificates.
Source(s):
NIST SP 800-53 Rev. 4 under Public Key Infrastructure (CNSSI 4009)

  A set of policies, processes, server platforms, software and workstations used for the purpose of administering certificates and public-private key pairs, including the ability to issue, maintain, and revoke public key certificates.
Source(s):
NIST SP 800-63-2 under Public Key Infrastructure (PKI) [Superseded]

  A Framework that is established to issue, maintain, and revoke public key certificates.
Source(s):
NIST SP 800-12 Rev. 1 under Public Key Infrastructure (PKI) (FIPS 186-4)

  A framework that is established to issue, maintain and revoke public-key certificates.
Source(s):
NIST SP 800-57 Part 1 Rev. 4 under Public Key Infrastructure (PKI)

  The architecture, organization, techniques, practices, and procedures that collectively support the implementation and operation of a certificate-based public key cryptographic system. Framework established to issue, maintain, and revoke public key certificates.
Source(s):
CNSSI 4009-2015 (CNSSI 1300)

  A framework that is established to issue, maintain and revoke public key certificates.
Source(s):
NIST SP 800-57 Part 1 Rev. 3 under Public Key Infrastructure (PKI) [Superseded]
NIST SP 800-57 Part 2 under Public Key Infrastructure (PKI)

  A set of policies, processes, server platforms, software and workstations used for the purpose of administering certificates and public-private key pairs, including the ability to issue, maintain, and revoke public key certificates. The PKI includes the hierarchy of certificate authorities that allow for the deployment of digital certificates that support encryption, digital signature and authentication to meet business and security requirements.
