Reducing Service Theft in DOCSIS Networks

1. IP Verification: Only the intended cable modem identified as originating from the associated IP address may download the configuration file

2. Single Download Only: The configuration file may only be downloaded once

3. Randomly Generated Filenames: The configuration filename is a randomly generated hex string created on-the-fly during the DHCP process, which eliminates the possibility of guessing configuration filenames

4. Configuration File Expiry: If a configuration file is not downloaded, the filename and related information regarding that file are destroyed after a configurable amount of time (default: 60 seconds)

5. TLV 19 and 20: The solution offers the ability to include TFTP timestamp and cable modem IP in configuration files.
