      The problem is that with encryption of static data (i.e. in a situation where you can't use something like Diffie-Hellman to negotiate a random key) you need to store the key somewhere and you have lots of options both good and terrible, for example:
      1. Derive it from the public information in the data

Passport number, date of birth, and expiration date are the only fields that have a check digit, which is why they were chosen as the base for the keys.

Forging (i.e. creating a passport with phony information but with a correct digital signature) is another story, very hard.

The reader then sends a random challenge to the chip, which encrypts it with the secret and send the result back. The reader does the same operation and compares the result. If it matches it considers that the chip knows the secret and is thus original.

    The key idea then is that the chip never sends the secret directly, so a cloner could never guess it, even if it could issue an unlimited number of challenges to the original chip. And without the secret, it cannot produce a clone that would authenticate.

And even if you don't have physical access to the passport, the key entropy is low, which helps eavesdropping considerably. You don't have to compromise the manufacturer or anything. The big challenge is coming up with a passport book that passes as a real one.

    Let's assume you get these politicians to understand some basics of encryption and physical security (and good luck with that). So, you now have a system where all people can be instantly identified and tracked by the government. Secure from... what, exactly? Secure from being tracked by unauthorized people?

    Who is unauthorized, and why? I certainly have no say in who gets authorized to track me. Thousands or hundreds of thousands of random workers have access to the "authorized" level. This doesn't sound very "secure" to me.

    It's like an electrocution collar you get to wear around town, "secure" in the knowledge that its encryption protocol is flawless. The only people who can activate it are from the police department, or friends of police officers, or people who sneak into the police building and use a computer there when nobody's looking. It is secure, and cannot be triggered except from the police station. Yet, in the broader sense of security, the mere fact of the collar's existence around my neck is the absolute opposite of security.

    It doesn't really matter how secure they make the algorithms. A system whose purpose is to authoritatively track and identify all individual humans "from above" is insecure, by definition.

    The article states that if you can see the human-readable part of the passport, or even just take a good guess at the details, you can extract the rest of the data from the RFID chip -- and clone it. Encryption is used to ensure that nobody can eavesdrop on a transaction once initiated, but that doesn't help the fact that every transaction is presumed legitimate -- and the very nature of RFID means that you aren't always able to know that a transaction is taking place. If there isn't a human being checking passports, just a machine -- and one day, that is exactly how it will be -- one of those cloned RFID chips will be enough to get you past it.

    Attempting to automate people out of the loop is asking for trouble, because we can always know what tests a machine is performing and falsify the results. Criminals are not stupid -- and smart people can often be bought. If the anticipated returns are high enough, you can be sure that someone will put up the stake. Security through obscurity is worse than no security, because it leads people to believe that their details are safe when they are not.

    They could have used a "secret" key (or something more sophisticated) because every immigration desk in every participating country then needs a secret key to "unlock" the info - and as soon as one of those (inevitably) leaks every passport in a dozen countries would have to be updated or replaced.

    The problem is that all any technological change like this can achieve is to make counterfieters work that little bit harder (the article didn't say if the info had been digitally signed - which would really help there and would be totally unrelated to anti-RFID-snooping measures).

    The RFID chip makes it much more difficult to alter a stolen passport e.g. by replacing the picture, BUT if you have the resources to clone ALL of the security features and print your own passport, you can conceivably clone the passport without even having to see it. However, on top of the marginally increased cost of manufacturing cloned passports due to the inclusion of an RFID chip (and the possible scenario of having to perform the brute force attack) it is now necessary that the bearer of the fake passport resembles the image of the person stored with the data on the RFID chip. A question that remains unanswered is whether it is possible to create an entirely fake passport including an RFID chip with the "correct" fictional info and picture. If it was previously possible to do this, as I must assume it was, and the inclusion of the RFID chip does not make it "impossible" within current technical limitations, then nothing has been gained.

    My non expert analysis of the situation is that the entire system of passport control (whether they be conventional, machine readable, RFID, etc.) depends on the ability of the people chekcing the passports. It is up to them to confirm whether the person presenting the passport is actually the person depicted in the picture as well as confirm the authenticity of the document itself. All these security features, or rather ANY security features that might be added will only serve to make it more difficult and expensive to acquire a fake passport that "works". These new security measures may not guarantee 100% the validity of the passport but it is a move in the right direction and better than nothing changing at all. Given the relatively strict time constraints placed by the US government I have to say that in my mind this particular technology is adequate for the time being. I must admit I have not seen or heard an alternative which might feasibly have been implemented within the same time frame on such a large scale. Do I believe that it is possible for a system to be devised that automatically confirms identity with 100% certainty? Possibly. Do I want that sort of security, no! The better these automatic systems become the easier they can be abused by people who are more concerned by their own pockets rather than my safety & privacy.

    As a side note, the article refers to a study where supermarket checkout cashiers were shown to fair badly at the task of matching faces to photos, however I would like to believe that those working in passport control have not only been specifically trained for this task but are also naturally better at it.

    The jist of the article is that they don't believe the security added by the RFID chip is worth what was paid for it not that it is inherently making the situation any worse.

    You made a good parallel when you compared this system to DRM. Both systems try to distribute similar content widely, for use by machines it has no direct control or communication with, yet keep that content secure. If it is not impossible to do this without violating best practices of cryptography, it is damned close to imposssible.

    However, it turns out they made the same blunder that tyro users of computer systems everywhere do: they chose a key that was easy to guess.

    From TFA:

    So they are using strong cryptography to prevent conversations between the passport and the reader being eavesdropped, but they are then breaking one of the fundamental principles of encryption by using non-secret information actually published in the passport to create a 'secret key'. That is the equivalent of installing a solid steel front door to your house and then putting the key under the mat.


    I think it can be convincingly argued that the reason they did this is that commercial product development is inherently prone to security blunders.

    Start from this well known cryptography maxim: any fool can create a system he cannot break into.

    The implication is that you need bring in outside people to criticize, even break your product. But that's not how businesses operate. Businesses run on sales; you have to convince buyers to have confidence in your product. Sales can't plant confidence in the customers' minds if they have doubts in their own. That's fine for sales, but what about engineering? Well, you don't start into the development of a product without at least a healthy dose of optimism. Businesses run on optimism. And they protect themselves by denial.

    Security problems are very easy to deny. There is no such thing as evidence of security; you can only try to find evidence of insecurity and fail. So how hard and long should you look? Most of the time if things look OK, they're taken to be OK.

    I think it's no accident that RSA, one of the best companies in the field, was started by academics. The academic approach isn't better in every case, but it does have a lot more respect for the importance of proving the null hypothesis.
