Discretix High Bandwidth Content
Protection Engines (DxHDCP)The DxHDCP security module provides a standards-based,
cost-effective, copy protection solution for digital video and
audio streams over wireline and wireless interfaces.The high-definition content market is booming, driven by the increased
availability of content and viewing devices. To protect this high-value
content, content providers demand robust copy protection. Developed and
licensed by Digital Content Protection, LLC – HDCP is the most widely-used
technology to protect HDMI, DVI and other interfaces. Furthermore, the
HDCP protocol is endorsed by the motion picture industry as the "technology
of choice" for secure distribution of digital content. Technical OverviewThe DxHDCP engine is a complete solution for protecting digital video streams, accelerating and securing all stages of the protocol including authentication, encryption, and key revocation. As shown in the block diagram the AES-based key protection module allows private keys to reside externally on flash memory, reducing the amount of required NVM. The key protection module decrypts the private keys, loads them internally during operation, while the HDCP cipher accelerates video encoding and decoding. Also available are the authentication and key revocation managers that discover and authenticate all connected HDCP ports and provide key revocation checks. Following the hot plug detect signal, the authentication session is established between transmitter and receiver. Once the authentication and key revocation checks are completed, video streams and data are decrypted or encrypted for display.
