The EIP-116 High-bandwidth Digital Content Protection Control Path module provides the required technology for implementing all the secure access, cryptographic computations and cipher engine as defined in the HDCP 1.4 and 2.2 specifications. This module autonomously runs one or more HDCP stacks.. It provides all the cryptographic functions for authentication, key exchange, locality check and certificate verification. The EIP-116 hardware-based acceleration offers significant advantages above a software only implementation for timing critical and performance/power optimized cryptographic operations.
The module includes an interface to Non-Volatile / One-Time Programmable memory (NVM/OTP) for retrieving the device unique keys, which must be programmed as part of the manufacturing process.
