High-bandwidth Digital Content Protection revision 2.0 is used to encrypt premium content at the final stage of the content distribution process. It encrypts content as it flows throughout the home from source devices such as DVD players and notebook computers to display devices such as High-definition TVs (HDTVs). It defines a standard, interoperable method for supporting wireless interfaces, including the ubiquitous Wi-Fi standard. HDCP revision 2.0 uses industry-standard public-key RSA authentication and AES 128 encryption. It also supports protection of compressed content, making it feasible to use relatively slow 50 to 200 Mbps interfaces. HDCP revision 2.0 also protects transmission of uncompressed content over faster 5 to 10 Gbps links.
