  1. Re:Brilliant! on Technical Analysis of XBox Save Game Hack · · Score: 1

    nyone here bright enough to suggest a good way to protect from this? My first thought was to sign the public key with another, use an X.509 certificate or something but the problem is that you can always patch the signature/certificate/checksum/whatever verification mechanism... So what is the solution?

    You'd have to put the key and the checking code into tamper-resistant hardware which then had the power to shut down the game and refuse to play it if the signature was bad. Ideally the hardware would be integral to the operation of the system so you couldn't just disable it.

  2. Dangerous and foolish on Protecting Cities from Hijacked Planes · · Score: 5, Insightful

    This is a terrible idea for many reasons.

    First, most cities are not "restricted airspace". There are no prohibitions against flying over all kinds of areas where just as much damage could be done as happened on 9/11. And in fact, you can't protect cities in this way, because they tend to put airports near cities. So this proposal fails to achieve its most basic security goal.

    In fact, most restricted airspace is over isolated areas and is used for military training. It is restricted only so that combat pilots don't have to worry about accidentally ramming into jetliners.

    Second, these days one of the main forms of security related restricted airspace is the Temporary Flight Restriction, TFR. This follows the president all over the country as he campaigns for the 2004 elections. But since the locations of the TFRs change daily and unpredictably, there would be no reliable way for the avionics to be loaded with the current TFR locations. Hence the proposal would fail to address one of the main current security concerns.

    Third, there are significant safety issues involved. Every system is prone to failure. What happens when the gadget mistakenly activates and starts trying to turn the plane? The pilot will be fighting with the controls at a time when he may be distracted trying to land in bad weather. The system could easily kill many more people than it would save.

    And fourth, there are occasions when there is a legitimate need to enter restricted airspace, such as during an emergency. A dumb gadget like this cannot be expected to understand that an engine is failing or that the control surfaces are damaged, and the pilot needs to get the plane on the ground pronto! Military bases, with their ultra-long runways and isolation from civilians, are ideal locations for emergency landings; but they are generally in restricted airspace. Again, imagine the scenario of trying to land a crippled airliner while battling a robot which insists that you don't have the right to land there!

    All in all this is such a bad idea that it's clear that no one involved has any experience with the aviation business and what the real security issues are.

  3. Gold's a senile crank on Solar Sailing and Physics · · Score: 2, Interesting

    I assume this is the same Thomas Gold, Cornell astrophysicist, who is best known for his Deep, Hot Biosphere theory, which says that oil and natural gas do not come from decomposing organic matter, but rather are inorganic products of the deep earth itself. Gold has predicted for decades that our oil and gas discoveries have but scratched the surface, and that there are incredibly more massive reserves waiting to be discovered below.

    Unfortunately for Gold, no convincing evidence for his theory has ever been found, and he is widely considered a crank. Now that he has been retired for several years, we have to consider him a senile crank.

    Certainly the current paper does nothing to change that opinion. Among the other obvious physics mistakes which have been pointed out, let's look a little closer at his final example, a light beam incident on a dark body. Gold purports to show that the body's velocity calculated based on momentum transfer is inconsistent with the velocity based on energy transfer. But this is an elementary mistake! Any calculation based on equating these two results for an inelastic collision (as when the incident particles are absorbed by the body) will show the same disagreement.

    What Gold neglects to consider is that some of the energy is absorbed as heat. You can't calculate the body's velocity based on the assumption that all the energy becomes kinetic. It is the momentum-conservation formula which correctly tells us what the final speed of the body will be.

    It's always sad to see a once-great mind descend into senility. I'm not sure whether it's even sadder when the mind was once a crank.

    That's right, and it's only going to get worse. The legal criterion is whether you have an "expecation of privacy". Well, walking around in public, you really don't. You've always accepted that people could see where you are and where you are going when you move around in public.

    The problem is that with the continuing advancement of sensor and camera technology, eventually virtually every square inch of public space is going to be watched. Then it is just a matter of software to track people as they move from place to place.

    In my opinion we should accept this, and make sure it's public. That is, let the cameras all be webcams on the internet, not Big Brother cams feeding into the police station. Then everyone will have access to the same information, and we won't be putting more power into the hands of the government.

    All else being equal, "open" surveillance is likely to happen. The only thing that would stop it would be if they passed a law making it illegal to put a webcam in front of your house aimed at the street, in a misguided attempt to protect privacy. All such laws would accomplish is to hide the problem by letting the government watch people in secrecy.

    You don't need to "crack it". Trusted Computing has as its design goal exactly this sort of functionality: allowing networks of computers to trust that all the systems will behave in a predictable way. No one seems to understand that Microsoft wants this kind of functionality. DRM is only part of the picture. TC allows for far more than DRM. It assists any application which involves a network that would benefit if the programs knew what was running on the other end.

    Microsoft has surely known all along that TC would allow for this kind of thing. Of course they probably neglected to mention it to the RIAA. But the genius of Palladium is that by allowing programs to prove that they will behave in a certain way, it solves the DRM problem at one stroke whle at the same time allowing for an infinite variety of new applications.

    This is what trusted computing will be like. But instead of your employer limiting you at work, it will be Microsoft limiting you at home. "Where the fuck do you think you're going!?"

    No, that's not correct. Doing this would reduce the sales of Microsoft software, and Microsoft's goal is to sell more software rather than less.

    Instead, trusted computing will add new capabilities to your system, while still letting you do everything you can do today.

    These new capabilities will allow "trusted" applications to report their identity unspoofably to remote servers. The servers can then refuse to supply content to users who aren't running software which will enforce DRM rules.

    So you will still be able to do what you can today; but maybe everybody else will be able to do a lot more, downloading legal content under DRM restrictions. It's not so much that Trusted Computing will restrict what you can do; it's that it opens up new possibilities, but only under rules that are effectively enforced.

  7. Re:who do you trust on A Critical Look at Trusted Computing · · Score: 1

    we all deal with 'trusted computing' to some extent or other. in any computer system there is a person/persons/entity that is trusted. in the simplest form it is supervisor/admin/etc. as you design a network you describe who is trusted.

    With Trusted Computing, it is the program which is trusted - to behave as it was coded to behave!

    I remember when I was a kid, there was a book distributed by the John Birch Society (ultra right wingers): "You can Trust the Communists" A shocking title for the days of McCarthyism. But that wasn't the whole title; there was a continuation in fine print: "(To Be Communists)".

    This is kind of how Trusted Computing works. You can trust a program - to be itself. If a local or remote system is running a given program, you can trust that the program will run as written. It may be buggy, it may be inefficient, but those are internal flaws. No one can impose their own rules on the program; no one can alter it, no one can peek into its memory. At most they can cut the program off and prevent it from running. But if it runs, it runs as written.

    Yes, I can presently trust that my browser is not lying to me. On a "trusted computing" platform, I will no longer have that trust, because I won't have the final say about what browser and how it's used.

    You won't be able to alter or patch your browser without the remote server being able to find out that you have done so. Once your browser is loaded into memory and is running, you won't be able to debug it or alter or inspect its memory. Those are the limitations imposed by the trusted computing concept. None of this changes how or whether your browser may lie to you.

    You will still have the final say about what browser to use and what you do with it. However since your browser can report its identity to a remote site in an un-spoofable way, it will increase the power of servers to decide which browsers to accept. Your only choice in some cases may be to refuse to visit certain sites, or else to use a specific browser that will honor some DRM rules, and which the site requires to be used for downloads.

    TCPA is a (possibly) good thing. Palladium/DRM, that's the real evil (from the consumer and OSS viewpoints, anyways).

    No, that's totally mistaken. TCPA (recently renamed TCG) is essentially identical to Palladium/NGSCB in its basic security goals. TCPA provides for exactly the same kind of features, including the "secure attestation" which is the core requirement for DRM.

    This is the feature whereby the TCPA chip (called the TPM) computes a cryptographic hash of the software that loads, and then reports this hash to a remote server. The server can use this to decide if you have loaded software that it will trust, and decide on that basis whether to download content to you. This is precisely how DRM is implemented and facilitated by trusted computing designs, and it is fully documented in the TCPA spec.

    The idea that TCPA=good and Palladium=bad is a myth. The systems are fundamentally the same, and they are becoming closer, in that TCPA V2 is probably going to basically be Palladium.

  10. Re:The meaning of trust on A Critical Look at Trusted Computing · · Score: 2, Informative

    In this context, trusted computing means that your computer program can be trusted to operate according to its software code. That implies that the end user (or anyone else) cannot debug, alter or inspect the program while it is running. All he can do is exert the ultimate control: pull the plug, shut down the computer, stop the program. But if it is allowed to run, it can be trusted to run according to its code.

    In practice this is achieved by having some secure hardware report a hash of the program's code as it is loaded into memory, and arranging that no other programs (or the user) can alter the program as it exists in that memory. Microsoft is augmenting the Intel memory management model to achieve this kind of protection.

    It's not a matter of the program lying to you as the user. You can trust the program just as much as anyone else - to run according to its code. You no longer have the power to alter the program and to make it run differently. But you can still trust it to behave as it was coded to behave.

    This means that trusted programs do have a certain immunity to viruses, in that if another program gets corrupted, it can't affect the trusted one. However trusted programs can still have bugs and so they will still be able to be subverted. All the "trusted" protection can achieve is to minimize the damage, so that one program which gets broken can't infect or alter others.

    This is such a terrible idea that it deserves all the ridicule and opposition we can muster. I'd rather suffer a thousand RIAA lawsuits than to put the government in charge of music and the other arts.

    As others have pointed out, iTunes demonstrates that people will be willing to pay for music if they can download it quickly and easily. That's all it's going to take, the carrot of easy and relatively cheap downloads, plus the stick of suing heavy file traders. This problem is about to be solved, and we don't have to get the government involved.

    This is not an exploit designed to show that biometric systems can be fooled or that you could create some kind of fake image that would match an existing one.

    The whole point is that this shows that biometric templates are privacy-sensitive. Previously it was thought that they could be stored and promulgated without interfering with anyone's privacy, because it was thought to be infeasible to start from the template and reconstruct personally identifiable information about the subject.

    The new paper shows that this is not true; from the templates, you can reconstruct an identifiable picture of the individual. That means that, for example, if you had a bunch of templates of people who went in for an AIDS test, you could re-create pictures of the people who went in, adequate to recognize individuals.

    This would therefore interfere with the privacy of those individuals. And that implies that templates need to be subject to the same kind of privacy restrictions as other forms of personally identifying information, a standard to which they have not traditionally been held.
