About BPI and BPI Plus
The Baseline Privacy Interface (BPI) and BPI Plus (BPI+) protocols provide cable
modems with data privacy across the Hybrid Fiber-Coaxial (HFC) network by
encrypting traffic between cable modems and the CMTS.
NOTE: For a cable modem to use BPI and BPI+, you must configure the
Baseline Privacy settings in the modem configuration file. This file downloads
during the transfer of operation parameters.You create configuration files
within the cable modem provisioning process. Refer to the FastFlow
Broadband Provisioning Manager CLI-based Administration Guide, or the
guide of your third party provisioning manager.
Both BPI and BPI+ provide authorization parameters and traffic encryption
keys that secure traffic between cable modems and the CMTS. In addition,
BPI+ provides:
■ Authentication of cable modems through digital certificates. A cable
modem can use a digital signature to verify that the software image it has
downloaded has not been altered or corrupted in transit.
■ Strong protection from theft of service. The protected communication
falls into three categories:
■ Best effort, high speed, IP data services
■ Quality of Service (QoS)
■ IP multicast group services.
