CONFIGURING BPI PLUS
CERTIFICATES
This chapter describes how to configure DOCSIS 1.1 BPI+ certificates. Cuda
12000 BPI+ certificate configuration conforms with Data-Over-Service
Interface Specifications: Radio Frequency Interface Specification,
SP-RFLv1.1-106-001215.
DOCSIS 1.1 BPI+ provides additional secure authentication of cable modems
through digital certificates. A cable modem can use a digital signature to
verify that the software image that it downloaded was not altered or
corrupted in transit.
For a BPI+ exchange between the cable modem termination system (CMTS)
and a cable modem, you must configure two types of digital certificates,
which are:
Manufacturer/CA Certificates. A cable modem sends a
Manufacturer/CA Certificate when sending authorization information to
the CMTS.
CM Certificate. The CM certificate is required when the cable modem
requests authorization.
