High-bandwidth Digital Content Protection

The system is meant to stop HDCP-encrypted content from being played on unauthorized devices or devices which have been modified to copy HDCP content.

Quote:
HDCP uses three systems:
1) Authentication prevents non-licensed devices from receiving content.
2) Encryption of the data sent over DisplayPort, DVI, HDMI, GVIF, or UDI interfaces prevents eavesdropping of information and man-in-the-middle attacks.
3) Key revocation prevents devices that have been compromised and cloned from receiving data.
