Using Palladium to Secure P2P Networks

    The $100 M blockbuster is a fixed cost that can be spread over all of the copies. So if you sell one hundred million copies (considering the global market of ~7 B people, not unreasonable) your cost per copy of media is $1. Now the pirate cost is still low, but in both cases "production cost" tends towards zero.

    Now, back to distribution.

    Assuming the pirate and the legitimate product have identical distribution and identical production cost, there is still the playback cost to the consumer. I claim that pirate material is MUCH more expensive to playback than legitimate. However, this cost is better measured in hours used than dollars spent.

    (1) Pirate CD/VCD media -- often the pirate media simply does not work. If the failure rate is 50%, your $2 pirate metallica disc now costs $4 on average. Now add in the time it took you to bring the disc home, put it in to your cd player, discover it does not work, return to the vendor and buy a new disc. You can save time brining a discman with you, but now you have to carry a discman and spend a minute or two trying to listen to the disc. Suppose 15 minutes of effort here.

    (2) Kazaa -- Take five minutes to look for the track you want, take another ten to download. You have spent 15 minutes acquiring a song which may be corrupt. Now burn drop it into winamp or burn it to CDR. Kazaa doesn't have a built in burning tool yet, so add in the cost of Nero -- either in dollars or the time it takes to obtain a pirate copy.

    (3) Bittorrent Video -- Take ten minutes to locate a torrent for your video of choice. Note that this video must be a recently released video or otherwise popular in the pirate world. Now take 8 hours to download the video. Spend another half an hour burning it to CD(s) so you can play it.

    So in case (1) you pay $4 for the pirate disc plus 15 minutes of your time. In case (2) you still contribute 15 minutes of time, but probably closer to $0.25 for CDR media. In case (3) you spend over eight hours acquiring the media.

    Now the class of consumers who have unlimited time or otherwise undervalue their time is limited to those who are either unemployed or employeed beneath some poverty line (in this case, defined for the benefit of this example). While a tiny fraction of thses unemployed consumers are independantly wealthy, we can ignore them. The remaining pirates steal because they cannot afford anything.

    Now the digital piracy is not the same as real world piracy. The architypical poor guy who takes a loaf of bread is actually depriving the hard working employed guy of his hard earned meal. In the digital case, the bread is still there, so the hardworking consumer may still benefit despite the theft.

    This does not mean that the industry will stop caring about piracy -- after all, the hardworking guy needs a good reason to believe that he should actually pay for his media. But it is clear that it is more efficient for the recording industry to build efficient distribution systems and spend minimal effort complaining about theft.

    How to attack a P2P network (aka, find 'em, fake 'em, and kill 'em):
    1. Find 'em: Break the confidentiality. If you can sniff the network, and gain access to it, then you can find who has stuff being shared and thus sue them out of existence.
    2. Fake 'em: Break the data's integrity. Basically, shove in tons of fake data to piss off other users.
    3. Kill 'em: Break the availability of the network. Screw with the protocol, drop packets, generate thousands of fake clients, flood off other clients with search requests.

    How to defend a P2P with something like Palladium:
    Basically, it breaks down to not letting untrusted clients into your network. Since you can now trust that the hardware is secured, and since every client has to be vouched for in order to get in, you can stop all three of the attacks dead in their tracks. A P2P can be trusted in that other clients it tries to connect to will be able to verify that trust mechanism using the very same secure computing methods that this stuff gives you.

    Think of it like this. I trust Bob, so I let Bob connect. Bob trusts Cathy, so I can get a network of trust relationships going. Obviously, somewhere, someone could break that trust chain, but the existence of the trust chain is a new thing that hasn't been implemented yet. Combine it with encryption to prevent sniffing the network or at least make it way too difficult, and I can build a trusted network over which anything can be shared, *and* know that nobody is hacking my clients on either the software or hardware level, such that they can see or send things that they shouldn't.

    Find 'em breaks down simply by going through enough nodes to make it impossibly difficult to track down where the hell the data actually is. This is already a nearly solved problem anyway, with stuff like FreeNet's method of ensuring that even the clients don't know what they're sharing.

    Fake 'em is broken by the trusted architecture. I can trust, to some degree, anyone on my network because of the chain. I can trust the client isn't doing shit it ain't supposed to be doing. I can trust that the hardware hasn't been modified to some degree. I can revoke clients by breaking the trust links to them or creating an "antitrust" kind of link that other clients might use as well. If someone injects fakes onto the network, I put down that I don't trust them, and voila, that propgates to those who trust me and so on. Creates a closed circle.

    Kill 'em is broken by the same trust relationship to some extent. If the client can't get into the network, he can't inject things onto the network. Once someone doesn't trust that client, it finds that nobody trusts him anymore. If someone is attacking via flooding, obviously there's not much you can do except block them down the pipe, but the trust chain lets me tell others on the network that this guy is a jackass and thus they don't trust them either.

    And so on.

    Using Palladium to secure P2P would be a nice idea if, and only if, anybody could create applications that took advantage of the Palladium chipset. MS gives everyone the impression that this will be possible by saying things like "everyone will benefit from this technology", but the truth is that Palladium will be very protected by heavy, restrictive licencing. That's pretty much guaranteed.

    After all, this is one of the most important parts of the plan. You have to pay to write apps that use it, and this will hurt the only competition MS has: software that doesn't cost any money.

    Does anyone think they'll really allow a P2P network to tap into its secure computing resources? I don't think so. They'll be really careful about who they license it to, no matter how much money's involved, because once you get viruses, Bonzi Buddies and spyware that's so secure that removal programs can't get them, or if the users start using Palladium in a way the big labels can't intervene, they'll have a huge problem.

One reference they omitted is Microsoft's EULAs which require forced upgrading and Microsoft's right to search your files and delete those they considercopyright infringing.

They promise to do it now, despite a lack of tools. Chances are that Microsoft will delete all peer to peer client programs they find.

    What good would "open implementations" of DRM do? Allowing others to control what your computer does with their file/data is the entire point of DRM. When that fails, M$ and the MPAA will create a censorship system under the guise they need to delete infringing files. To do so, a M$ controlled DRM system will need to be in place--to trap everyone into only using M$ systems, and/or to hide the fact they are censoring people.

    P2P will NOT be 'secure' on a Pull-a-DRM. It will not work! Even if the Pull-a-DRM system is broken by 3 lines of script, those who use the 3 lines will be sued or charged under some **IA brokered law. Sharing will be *restricted* to what the **IAs allow through their 'special' keys.

So we scratch our pockets and go see Bill and try to ge the software validated - Valdation mechanism is pricy yet simple for any normal vendor.
