Configuring BPI and BPI+ Parameters

Configuring BPI and BPI+ includes the following tasks:

■Configuring Authorization and Traffic Encryption Keys. This task applies

to both BPI and BPI+.

■Configuring Trust and Validity for Manufacturer Certificates. This task

applies to BPI+ only.

■Configuring IP Multicast Address Mapping. This task applies to BPI+ only.

■Viewing privacy keys. This task applies to both BPI and BPI+.

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 configur ation 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 Ad ministration 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.
