Introduction and Purpose

The present document is part of a series of specifications that define the third generation of high-speed data-over-cable systems. This series was developed for the benefit of the cable industry, and includes contributions by operators and vendors from North America, Europe, and other regions.

The present document defines the Base Line Privacy Plus (BPI+) architecture which covers CM authentication, key exchange, and establishing encrypted traffic sessions between the CM and CMTS. Early Authentication and Encryption (EAE) applies BPI+, earlier in the provisioning process (see clause 8). This specification also defines security features for the CM provisioning process, which includes Secure Software Download (SSD).
