PKI (Public Key Infrastructure) is the term used to describe the components and processes required to use digital certificates. A PKI includes a certification authority that issues the certificates. Other typical PKI components are a registration office, which can be used to apply for a digital certificate, and a directory service, which can be used to retrieve digital certificates. The most important process in a PKI is called “enrolment”. This includes applying for, generating and issuing a digital certificate.
