Cisco 6800 Series Provisioning Guide

The upper half of the diagram shows the Provisioning Server Root Authority that is used to sign the individual
provisioning server certificate. The corresponding root certificate is compiled into the firmware, which allows
the phone to authenticate authorized provisioning servers.

Digital certificates can be used to authenticate network devices and users on the network. They can be used
to negotiate IPSec sessions between network nodes.
A third party uses a Certificate Authority certificate to validate and authenticate two or more nodes that are
attempting to communicate. Each node has a public and private key. The public key encrypts data. The private
key decrypts data. Because the nodes have obtained their certificates from the same source, they are assured
of their respective identities.
