SCTE 23-2 2002

The intent of this BPI+ specification is to describe MAC layer security services for Data-Over-Cable Systems (DOCS) CMTS-CM communications. BPI+ security goals are twofold:

• provide cable modem users with data privacy across the cable network, and
• provide MSOs with service protection; i.e., prevent unauthorized users fromgaining access to the network's RF MAC services.

BPI+ provides a level of data privacy across the shared medium cable network equal to orbetter than that provided by dedicated line network access services (analog modems or digitalsubscriber lines).The protected RF MAC data communications services fall into three categories:

• best-effort, high-speed, IP data services;
• QoS (e.g., constant bit rate) data services; and
• IP multicast group services.

The earlier BPI specification [DOCS2] had "weak" service protection because the underlyingkey management protocol did not authenticate CMs. BPI+ strengthens this service protectionby adding digital-certificate based CM authentication to its key exchange protocol.
