Open Cable Standard Not So Open

Mike Hicks writes "A few days ago, I heard about the FCC approving new rules for standardizing digital cable in the US. This involved using a set top box or tuner integrated into a TV along with a smart card (much like digital satellite services). Unfortunately, it looks like the standard (believed to be OpenCable) is meant to tightly control the hardware and software that can be used, probably making any open-source implementation very difficult if not impossible.

      I don't understand how the set top box being open source is supposed to have anything to do with piracy. Piracy is the theft of information. Every company in the world is worried about the theft of their information. The fact that they use open source software does not impact that. What impacts that is how well they secure that software and protect the information that they don't want stolen.

      For the case of the cable company the issue is this: get the encryption done correctly, and it won't matter if the software processing the encrypted stream is open source or proprietary. What will matter is if the end user has the right key. Which, presumably, will be distributed on a tamper-resistant smart card which is programmed not to release the key.

      Perhaps it's just an accident on your part, but you seem to be suggesting that there's some sort of implicit relationship between open source software and piracy. If it's an accident, then ok. But if you really believe such a relationship exists, you need to back it up because I don't seen any such relationship.

      No, you've missed the point! I wrote the email that was quoted in this article, so I have a vested interest in clearing this up. :)

      OpenCable has gone through great lengths to decouple the decoding/display/application stuff from decryption and access control mechanism. Encryption and Access Control is handled by the cable company's POD (Point Of Deployment) module which will take the form of a removable PCMCIA card or similar. Each cable company could implement different encryption and access control systems by using different POD modules, so even if one system is hacked there would be others.

      The main point here, though, is that you're not handing the "hackers" the "keys" to the decryption system any more than you are by giving them a modern digital cable box. It's just a shame to build a system that would otherwise be so perfect for an open-source implementation and then lock it down due to DRM (instead of technological) concerns.

      Now, if you had full control over the box's hardware, how difficult could it be to rig something up that grabs any channel you want it to?

      Very difficult if the system is setup correctly and you have two-way communication plus neighborhood segmentation.

      Step 2. Distribute smart cards with unique private keys signed by the cable company.

      Step 4. Setup key distribution system whereby the cable box requests a new channel block decryption key once per hour using its private key to sign a request.

      This system makes it fairly difficult to steal cable. If you try to clone someone else's cable box private key, the cable company will see a duplicate channel block key request.

      You can't modify your cable box to ask for say, the HBO channel block key because your private key itself won't be authorized by the key distribution servers at your cable company.

      You could setup an online key distribute system to dup your key out to other people in your neighborhood, but it would be limited to people in your neighborhood (since other neighborhoods have different keys).

This is for mostly historical reasons, but the way they hold onto it now is that they have monopolies on the conditional access (content protection) systems, which are hardwired into the boxes.

    The cable companies (Comcast, Time Warner, et al) want to open up the standards provided to set top box manufacturers so that consumer electronics companies (Sony, Samsung, et al) can compete with Moto and SA for the business, driving the prices for STBs down. STBs are one of the largest capital costs/subscriber acquisition costs for a cable company. The secondary goal (beyond lower STB prices) is moving the STB purchase into the retail chain, so that cable companies don't have to carry that burden unless they want to). The way they plan to do that is a conditional access module in the form of a PCMCIA card (more or less), which the user purchases or leases from their cable company, and repurchases or leases if they move with the STB they own.

Home Depot will still pay for product placements in Trading Spaces. Maybe the Super-station will go away - but the cable companies, and popular channels, need not.

They will need to realize that they must beat file-sharing on features. People will give up hunting around for a good (not mislabeled)256kbps rip of Britney's newest song - if they know they can just hit iTunes or its ilk and cough up $1.
