High-Bandwidth Digital Content Protection better known by its acronym HDCP, may have been compromised according to claims from net sources. Details on how and who leaked the master key have not yet surfaced.
HDCP was invented by Intel to be a cheap-to-implement, high-performance cryptographic system suitable for use in audio and video applications. Its purpose was to create a secure digital path that could not be eavesdropped, so that pirates would not be able to make high-quality digital copies of high-definition video. HDCP also provides a mechanism for key revocation: if a device's key has been leaked, it can be added to a list of revoked keys, effectively blacklisting it and preventing it from being used for playback of encrypted content.
