Intel Confirms That HDCP Master Key is Cracked

By - Source: Tom's Hardware US | B 34 comments

The high-def digital media has been freed, for better or worse.

HDCP doesn't have to be a hindrance anymore.HDCP doesn't have to be a hindrance anymore.

High-bandwidth Digital Content Protection, which is more commonly known abbreviated as HDCP, has been confirmed by Intel as cracked.

HDCP, which is the DRM scheme for HD hardware such as HDTV, cable boxes and Blu-ray Disc players is exposed and wide open for those who wish to bypass it. More specifically, the master key that is used for encryption is floating around on the internet freely for anyone who wishes to make use of it.

"We can use it to generate valid device keys that do interoperate with the (High-bandwidth Digital Content Protection) protocol," Intel spokesman Tom Waldrop told Cnet.

"What we have confirmed through testing is that you can derive keys for devices from this published material that do work with the keys produced by our security technology," he told FoxNews.

Intel doesn't seem too stressed over the defeat of HDCP, however, as the current scheme still stands to be an inconvenience to all those other than the most dedicated.

"For someone to use this information to unlock anything, they would have to implement it in silicon -- make a computer chip," he added. "As a practical matter, that's a difficult and costly thing to do."

    will_chellamIt's like an uncrackable safe - all safes can be opened - if they couldn't, they'd be a tomb.

    If it can be built, it can be destroyed.

    People have been bypassing HDCP altogether for years now, what difference does this make?

    Most people will never know and Intel understand that if there is a lock, eventually, someone will find they way to open it.

    They are trying to play it down but you can use an FPGA & a DSP (these are both generic chips that can be field programmable)

    Total cost of dev kit cost will be around $100 plus ~$30 for the FPGC+DSP chip, suct as Analog Devices Blackfin. Anyone who has enough math+programming knowledge to use this key can easily program these chips too.

    kind of anti-climatic at the end - you have to make your own silicon chip.
    maybe this is true for dedicated HW devices but not for PCs.

    now maybe you can buy a monitor and use it without some stupid sync error :)

    Nobody thought that HDCP would be uncrackable. It was designed to inconvenience typical users enough to keep them from copying media, motivated ones used the analog loops or bought some other hardware setup. I hate this "I sell you stuff in a box so you can play it on an certified box the way I want" business model. Also you should know that there are many countries where it is legal to copy movies for personal use, but making/selling/using hardware that circumvents protection like HDCP gets you jail time... so the system works the way it was intended $$ :)  BTW Where does DHCP certification money goes to?

    Better HDTV rips? That's why Intel isn't freaking out about it. Nothing changes.

    As usual the spin doctors are on the job. HDCP was not cracked. To use the word "cracked" is to make it seem as if the evil hackers have once again done their devious work and the world is under attack. HDCP was leaked by someone. They didn't reverse engineer it. Someone with access pasted to a website. Lets have at least some honesty. There isn't much left in journalism anymore.

    Yeah. Or wait until someone starts selling mod-chips and instructions on how to install them.

    I bet someone has put his hive of PS3s, or something like that, to work a long time ago and it just finished decrypting.

    Oh and if it's leaked, maybe the leaker was on crack when he pasted the key on-line so we can still say "It was cracked" :)

    Why on earth would it need to be implemented in silicon? You can translate just about anything from architecture to architecture, there was Pear-PC for running OSX on an x86 PC back when Macs used PowerPC chips, I believe that guy doesn't have a clue what he's talking about.

    HDCP is one of the worst implementations of drm ever. I never was even sure what the point of HDCP was except to intentionally piss customers off and increase their revenue.

    For a little while I HAD to get cracking software to strip my legally owned Blurays of DRM because I had a HDMI cable that was not "HDCP Compliant". Naturally, there was nothing wrong with the cable - it plays BDs flawlessly.

    Now that I got a new HDMI cable, I still get my HTPC is not "HDCP Compliant" every now and then even though ever item, wire, and device I have is HDCP compliant. It is very aggravating!

    That's a challenge to developers. It's not bad.

    Well it only takes one of those "most dedicated" and enough upload speed that the result is being spread all over the net.

    I have no idea why they even bother creating these content encryption schemes, they have been and they will always be cracked. Just a waste of engineer's time.

    If it has been made by man, they will be cracked by man, 100% guaranteed.
