Automated generation of certificates from a Certificate Authority through the use of an Enrollment Agent. Devices needing certificates generate the necessary keys and package public key information with other identifying information about the device and send this information to an Enrollment Agent. The Enrollment Agent takes this information and submits it on behalf of the device to a Certificate Authority, managing the interaction with the Certificate Authority on behalf of the device. The Certificate Authority signs the request, returning a certificate to the Enrollment Agent. The Enrollment Agent packages the certificate along with the other certificates needed to establish a chain of trust and returns these to the device. Certificates may be stored in the device in flash memory. The process is secure as long as the communications path between the devices and the Enrollment Agent is secure; a secure VPN or HTTPS: connection allows the devices and the Enrollment Agent to be in separate locations.
