HDCP 2.0 Encryption Suite

特色

• Support for HDCP 2.0
• Support for all HDCP configurations:
• HDCP Transmitter (-TX)
• HDCP Receiver (-RX)
• HDCP Repeater (-RPT)
• Implementation of the HDCP Authentication protocol:
• Authentication and Key Exchange (AKE)
• With Key Derivation
• Locality Check
• Session Key Exchange (SKE)
• Authentication with Repeaters
• Data encryption:
• Utilizes HDCP Cipher (AES-128-CTR)
• Includes the Link Synchronization
• Transmitter and Receiver utilize the counter information in the PES Private Data
• FIFO-like flow-through interface with flexible bit width; simple integration into the datapath.
• Microprocessor-friendly interface for programmable I/O is optional
• Components
• HDCP software written in C (CPU subsystem is not included)
• Hardware accelerators
• AES1-CTR-HDCP: AES encryption/decryption capable of handling the PES streams
• RSA2: An RSA hardware accelerator (optional, high-end CPUs can use the software implementation)
• TRNG1: A true random number generator (optional, if entropy bits are available in the design, a software implementation can be used)
• SHA2-256: A Sha-256 hash accelerator (optional, most CPUs can use the software implementation)

应用

• Digital rights management (DRM)
• HDCP 2.0 implementations for generic wired and wireless interfaces
