Not to be confused with. High-bandwidth Digital Content Protection ( HDCP) is a form of digital developed by to prevent copying of digital, audio & video content as it travels across connections. Types of connections include (DP), (DVI), and (HDMI), as well as less popular or now deprecated protocols like (GVIF) and (UDI). 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. Before sending data, a transmitting device checks that the receiver is authorized to receive it. If so, the transmitter encrypts the data to prevent eavesdropping as it flows to the receiver.
In order to make a device that plays HDCP-enabled work, the manufacturer must obtain a license for the patent from Intel subsidiary Digital Content Protection LLC, pay an annual fee, and submit to various conditions. For example, the device cannot be designed to copy; it must 'frustrate attempts to defeat the content protection requirements'; it must not transmit high definition protected video to non-HDCP receivers; and DVD-Audio works can be played only at -audio quality by non-HDCP digital audio outputs (analog audio outputs have no quality limits).

Intel has confirmed that the crack is real, and believes the master key was rather than leaked. In practical terms, the impact of the crack has been described as 'the digital equivalent of ', and of limited importance for consumers because the encryption of high-definition discs has been, with the loss of interactive features like menus. Intel threatened to sue anyone producing an unlicensed device. This section includes a, but its sources remain unclear because it has insufficient.

The attack used the fact that the pairing process sends the Km key obfuscated with an. That makes the encryptor (receiver) unaware of whether it encrypts or decrypts the key. Further, the input parameters for the XOR and the AES above it are fixed from the receiver side, meaning the transmitter can enforce repeating exactly the same operation.
Such a setting allows an attacker to monitor the pairing protocol, repeat it with a small change and extract the Km key. The small change is to pick the 'random' key to be the encrypted key from the previous flow. Now, the attacker runs the protocol and in its pairing message it gets E(E(Km)). Since E() is based on XOR it undoes itself, thus exposing the Km of the legitimate device. V2.2 was released to fix that weakness by adding randomness provided by the receiver side. However the transmitter in V2.2 must not support receivers of V2.1 or V2.0 in order to avoid this attack. Hence a new erratum was released to redefine the field called 'Type' to prevent backward compatibility with versions below 2.2.
