Abstract
A method for authentication of network devices in a data-over-cable system is provided. The method includes storing a network address for customer premise equipment and a network address for a cable modem associated with the customer premise equipment in an internal table on a cable modem termination system during an initialization sequence for the customer premise equipment. If the cable modem termination system has to re-boot, or has to re-establish a connection to a cable modem, the internal table is used to prevent the cable modem from registering "rogue" network devices associated with a cable modem on the cable modem termination system. The authentication method allows a cable modem termination system to authenticate customer premise equipment or other network devices associated with a cable modem using internal tables. This authentication helps improve the security of a data-over-cable system and makes it less vulnerable to attack.
