The DRM Scorecard

An anonymous reader writes "InfoWeek blogger Alex Wolfe put together a scorecard which makes the obvious but interesting point that, when you list every major DRM technology implemented to "protect" music and video, they've all been cracked. This includes Apple's FairPlay, Microsoft's Windows Media DRM, the old-style Content Scrambling System (CSS) used on early DVDs and the new AACS for high-definition DVDs. And of course there was the Sony Rootkit disaster of 2005. Can anyone think of a DRM technology which hasn't been cracked, and of course this begs the obvious question: Why doesn't the industry just give up and go DRM-free?"

      Locks are a good way to keep honest people honest, but they should be simple and unobtrusive. The reason why we have key locks on our front doors instead of complicated biometric systems (this may be the wrong audience for this comment) is that they are simple, cheap and less prone to failure. The DRM systems created today are complicated, expensive (especially in hardware cost), unreliable and confusing. A simple restriction against copying marked files in software would do just as well to keep honest users honest and would avoid all the complexity and expense.

      Neither DRM nor simple copy prevention will protect against users who really want to get around it as the problem of protecting such media is fundamentally impossible to solve. Even if a perfect system could be devised, until the day CDs become obsolete unrestricted copies will be widely and easily available. Neither consumers nor hardware manufacturers have much incentive to actively support DRM, even if most consumers are only apathetic. Simple economics and the constant competition between vendors will prevent DRM from gaining the strangle-hold required for it to be effective, which is fortunate for us all since such a strangle hold would create its own problems.

      The best form of DRM would be standardised machine-readable copyright information that could be embedded as metadata in or alongside a file. This would at least force users to knowingly override copyright restrictions when they copy restricted files.

    From Wikipedia:
    "Cryptanalysis researchers demonstrated fatal flaws in HDCP for the first time in 2001, prior to its adoption in any commercial product. Scott Crosby of Carnegie Mellon University authored a paper with Ian Goldberg, Robert Johnson, Dawn Song, and David Wagner called "A Cryptanalysis of the High-bandwidth Digital Content Protection System". This paper was presented at ACM-CCS8 DRM Workshop on November 5, 2001.[1]

    The authors conclude:

    "HDCP's linear key exchange is a fundamental weakness. We can:

    * Eavesdrop on any data
    * Clone any device with only their public key
    * Avoid any blacklist on devices
    * Create new device keyvectors.
    * In aggregate, we can usurp the authority completely."

    It must be noticed, however, that for this attack you first have to break Blom's scheme (the linear algebra based key exchange system). In the case of HDCP you need a minimum of 39 device keys in order to reconstruct the secret symmetrical master matrix that has been used to compute all device keys.

    Around the same time that Scott Crosby and co-authors were writing this paper, noted cryptographer Niels Ferguson independently claimed to have broken the HDCP scheme, but he did not publish his research, citing legal concerns arising from the controversial Digital Millennium Copyright Act [1].

    The most well-known attack on HDCP is the conspiracy attack, where a number of devices are compromised and the information gathered is used to reproduce the private key of the central authority.

    From Wikipedia:

    The Smart Cow Problem describes the method by which a group of individuals, faced with a technically difficult task, only requires one of their number to solve the problem. Having been solved once, an easily repeatable method may be developed, allowing non-technically proficient entities to accomplish the task. The term Smart Cow Problem is thought to be derived from the expression: "It only takes one smart cow to open the latch of the gate, and then all the other cows follow." [1]

    This has recently been applied to Digital Rights Management (DRM), where, due to the rapid spread of information on the internet, it only takes one individual to defeat a DRM scheme to render the method obsolete. [2]

  23. The Alice and Bob analogy by Spy+der+Mann · · Score: 4, Insightful

    No, it's flawed because it CAN be cracked easily: The decrypting key is in the firmware contained in your DVD player.

    In cryptography, we have an explanation using Alice and Bob. Alice is communicating with Bob, while Eve (eavesdropper) tries to decrypt the message. Alice and Bob have the key to decipher the message, but Eve doesn't. She wants to decrypt the communication *without* the key.

    A --- E --- B

    Alice in this case, is the Digital Media producer (or encrypter), and B is your DVD. You're Eve. The problem with DRM is that Eve *HAS* the key. By cracking the DVD software (some disassembly, debugging and you're done), Eve can obtain the key from Bob.

    A --------- B E

    This is the problem with DRM. It's flawed by design. The DMCA is a legal "patch" to this algorithm, punishing Eve if she gets the key from Bob. The problem with DMCA is that the punishment doesn't apply to all countries, and trying to enforce it results in attacking freedom of speech.

    I dont like the analogy of a bank vault at all. Its not like people are breaking into a video store and stealing videos. These are usually people who have lawfully purchased a video and want to use it for their own private purposes but this has been restricted by DRM. DRM circumvention is often an attempt for a consumer to simply use something they legally purchased for their own private use, such as making back up copies or playing it on their computer, or copying to their ipod. I dont see any problem with that unless they are distributing it to others, Once a person has legally obtained some work, it should be theirs to do as they please with it for their own private use.

    We already have copyrights to protect the producers of works. DRM is going too far as it restricts the users rights to use something for their own private use, for which they have legally purchased.

But this has a history, at least in Europe, of being cracked, holes found in the algorithms and all sorts of fun, then 6 months after it gets public known they change encryption system, and the TV pirates can start over. The encryption systems have in that way gotten so tough to crack that the pirates have found other ways, the most common way to get around the encryption today, is to get a receiver of which you can replace the firmware, and in that way get the receivers to share the smartcards with each others over the internet, for the time being the TV providers knows it's happening, but they fail to figure out how to prevent it, so instead they spread rumours that their encryption providers in Israel are able to detect when cardsharing occurs, but I have yet to hear about them catching anyone in that way.

    Locks are a good way to keep honest people honest, but they should be simple and unobtrusive. The reason why we have key locks on our front doors instead of complicated biometric systems (this may be the wrong audience for this comment) is that they are simple, cheap and less prone to failure.

    Remember the front door is public, the lock is public but only the owners have the key. The front door system works because not everyone who can get to the door has the key. DRM simply doesn't work because you have the content, the lock and the key.

  31. DRM is here to stay! by dhavleak · · Score: 3, Insightful

    Not trying to be a troll. But I strongly disagree with the hive-mind about DRM being as hopeless as the comments proclaim.

    Frist off, digital piracy isn't that different from brick-and-mortar piracy -- sellers will always try to find ways to prevent theft, and those who want to pirate stuff will always find ways to circumvent the checks. This is human nature and the it'll probably never change.

    Second, while we (rightly) think that the RIAA could save itself a lot of effort by revamping its model, that argument doesn't scale to other media. For example, movies. Movies are expensive to make, and don't sell in the same volumes as songs. The RIAA might easily solve its problems by moving to an AllOfMp3-like model, and pricing structure. But the MPAA won't be able to do the same -- charging 10 cents a movie will mean that they need to sell about 150 times the volume to make similar profits. Charging even $4 a movie will be enough incentive for people to go back to bittorrent. So clearly, its a never-ending tug of war, and while we think the RIAA/MPAA should in good faith adjust it's pricing model etc. the MPAA (at least) can't rely on the same good faith from its customers.

    But of course, the RIAA and MPAA are not blameless. And neither are Apple and MS and anyone else creating DRM schemes for multimedia formats (in fact, perhaps the Apple and MS folk are more guily than the RIAA/MPAA. Thier real sin is, they are trying to exploit a side-effect of DRM by not openly licensing thier DRM schemes and not making them interoperable/platform-agnostic. They have seen the side-effect of locking in customers by not licensing thier DRM schemes and by using proprietary formats, and they're frothing at the mouth with the possibilities of locking in customers, and getting duplicate revenues from those that do defect.

    At one point, I was actually willing to give MS some props for trying to rally the industry around a single DRM scheme (PlaysForSure) and keeping the API for it open. The lack of PlaysForSure on Macs and Linux is a big problem, and using WMA is a bigger problem, but the real sin was when they came out with yet another DRM system for the Zune. (Unless their PlaysForSure contracts made it a necessity by stipulating that MS will never come out with a PlaysForSure device or something like that - I wonder).

    And Apples fault is in how they choose to license FairPlay. They seem to have some arbitrary 'coolness factor' that needs to be met before they license FairPlay (which they do license out). For example, it's clear that the Xbox ppl have given iPod integration a lot of importance, and they must surely have approached Apple to license Fairplay so that even protected songs could be streamed to the 360 from a PC/Mac or iPod. The fact that this doesn't work today can only be because Apple did not license FairPlay. A terrible sin, for what would have been a very cool and easy to use feature. They did not think about the benefit to their users first -- they thought about lock-in instead.

    This is really what's wrong with DRM today. Companies are having a field day with trying to lock in consumers, and not giving any thought to enabling them to use thier property in as many fair ways as possible. The focus is completely on lock-in, and disabling, rather than enabling, and maintianing an audit trail without hindering.

    The solution might come from the market, in time. But for that people need to be very vigilant about shunning DRM schemes until these companies learn thier lesson and start inter-oprating with each other. That doesn't look like its happening anytime soon -- what with iTunes downloads crossing the 3 billion mark the other day. Consumers only have themselves to blame if they endorse DRM in this manner.

    The solution might come faster through litigation. Either through class action lawsuits (iTunes customers who want to migrate so a non-apple mp3 player, who get pissed because thier collections are now worthless), or Congress (ve
