    I should bookmark that article so I can bring it up when I see the following headline "Unhackable chip hacked..."

    Nothing is unhackable. They say that every damn year! Someone comes out with something that can't be hacked, then it's hacked.

    We are not amused.

    I dunno. Did you read that article? It will take quite a concerted effort to break that. It certainly won't be done by some casual hacker, to be sure.

    That wasn't the point though.

    If I had a $ for ever time a company/security firm said some thing was uncrackable I'd be a very rich man :D

    Give it some time once the device is in public hands to be cracked/exploited.

    One thing confuses me here, what is the difference between using a detector and listening ? I get the idea but how can the two parties "measure certain properties of the photons" yet not be susceptible to man-in-the-middle attacks ?

    IF there is a way to make it > there is a way to break it :cheers

    Indeed there is no such thing as unhackable.

    Didn't Apple think the iPhone (3G) was unhackable too ?

    Lets see how UNHACKABLE it really is.

    If I had to guess, I would say that it takes advantage of the strange phenomenon that a light particle will behave differently if it is observed than if not. If it does, it truly is unbreakable unless the laws of physics are changed. Of course if that happens, the universe will unravel and we're all doomed.
    DOOOOMMMMED!

    For a detailed explanation, look up "double slit experiment".

    If the human mind was used to help encode it, the human mind can help decode it as well.

    Not really, you can't crack strong encryption just because a human made it. This has been proven time and time again, why do you think law enforcement so hate the fact that bad guys can hide stuff from them.

    You can attack other parts of the process but the actual encryption algorithm, or cipher, if based on good strong cryptography can't be broken, at least not without using a unfeasible amount of time and CPU power. Sure as CPU's get's faster and faster the bit strength needs to be increased but that's easy, the only problem is then you also need more CPU power and time to decrypt which on low powered devices is a problem, which is why you for example have both symmetric and asymmetric algorithms.

    So no everything is not crackable just because it was made by humans, if that was the case you wouldn't be able to do online banking safely (cryptographically speaking, i.e. SSL). No one in there right mind (except cryptographers for academic purposes) would try to attack/crack the actual encryption algorithm if already proven to be cryptographically strong, you would attack other parts of the process and try to find a way of getting around having to actually brake the encryption. Like it was done with DVD DRM. Or for example if the process uses a human generated password and the password is say "god", then your password is weak and it won't matter how strong the encryption is, anyone with half a brain can do a dictionary attack or even guess the pass.


    The point here is that the random generator used for the key generation in quantum cryptography is truly random, and by the very nature of the process it is a one-time pad. Quantum cryptography is only used for key distribution. It is the generating of the key which can't be "listen to", as that would "cause photons to be changed or destroyed".

    Background on Quantum Key Distribution


    However, there are still many theoretical attacks that are possible.

    Quantum_cryptography - Attacks

    Experimental demonstration of time-shift attack against practical quantum key distribution systems



    And what about other issues, like jitter in the optical transfer, what happens then ? Is the properties of the photons which each communication partner measure then compromised ? Would it mean that until fixed the key distribution/generation can't be done, if so it doesn't seen like a very robust way of doing key distribution.

    I still stand by what I said.... everything is hackable. It doesn't really matter if you hack it by going around the encryption... it's still hacked.. and that's the only thing that matters.

    Yup...even if it takes 10 years.....It still will be hacked...

    So Very Very True...If it can be made...it can be BROKEN!!!

    Everything can be hacked, even if you need physical access to the chip etc...you can still hack anything.
