Public Key Infrastructure PKI is a critical enabling technology for Information Assurance IA services to support seamless secure information flows across the Global Information Grid GIG and at rest. Using authoritative data, obtained via face-to-face identity proofing, PKI creates a credential that combines this identity information with cryptographic information that is non-forgeable and non-changeable. In this way, PKI provides a standards-based representation of a physical identity in an electronic form. With this PKI-based identity, data sharing amongst appropriate, broad, and dynamic Communities of Interest COI will be enabled. PKI IA services enable and promote a common ubiquitous secure web services environment it allows war fighters and other authorized users to securely access, process, store, transport, and use information, applications and networks regardless of technology, organization, or location. PKI enables the integrity of dataformsorders moving within the GIG, via use of digital signatures. PKI enables management of identities operating in groups or certain roles within GIG systems. PKI can also ensure the integrity and confidentiality of what is operating on a network by provision of assured PKI-based credentials for any device on that network.
