Abstract
Secure downloading of a certificate to an ONU (Optical Network Unit) over an ODN (Optical Distribution Network), by storing the certificate in association with an OLT (Optical Line Terminal). The OLT instructs the ONU to download a file comprising the certificate, and optionally also comprising an address to an ACS (Auto-configuration Server), and indicating the file location. Thereby, the ONU is able to fetch the file over the secure ODN, unpack the file, install the certificate, and connect to the ACS for provisioning.
