    HDCP Copy Protection Cracked?

    A tweet may be the undoing of the so far uncracked HDCP copy protection, used in the HDMI interface, including for Blu-ray. Someone has posted to Twitter the HDCP master key, or at least allegedly the master key, and if true, it means that HDCP as a form of DRM has just become useless.

    The master key would allow new source and sink keys to be created, in effect, fooling the system into thinking that an illegitimate device is in fact a legitimate device, thus rendering the whole system less useful than DVD's CSS copy protection.

    The only way to solve this problem is to issue new master keys, but this would render many HDCP capable devices useless if they can't be upgraded via firmware.

    There's no word on who the mysterious hacker is, nor whether the key is even real, but it just goes to show that there is no such thing as a hack-proof DRM scheme, and if HDCP isn't cracked today, it will be one day.

    More:

    If links appearing on Twitter are to be believed (and right now there's no reason to doubt them) then the master key for High-bandwidth Digital Content Protection (HDCP) has been revealed, making the DRM baked into devices such as Blu-ray players effectively dead.
