What is Public Key Infrastructure (PKI) and how will CAC use PKI?
PKI is the basic framework and services that are being put in place within DoD to ensure information systems security. It provides the capability to attach digital signatures to electronic documents and to encrypt and decrypt electronic documents for secure transmission. The CAC will serve as the user’s PKI token, which means that the chip located on the CAC will be used to store the user’s private key identity, email, and encryption certificates. These certificates are used to gain access to PKI-related services.
