Design and verification of High-Bandwidth Digital Content Protection transmitter authentication

High-Bandwidth Digital Content Protection(HDCP)-it is a technology method which is used to protect the high definition signs. This paper focuses on design and verification of authentication part, the most important of a HDCP2.2 transmitter. Besides architectural analysis and design approach discussions, a detailed micro architecture, including signature verification, key encryption and revocation list comparison, is proposed and verified. The HDCP transmitter authentication part based on RSA, SHA256, HMAC, AES algorithm could verify the System Renewability Message from video source, accomplish the c for HDCP receiver and provide the session key for encryption.
