    'Unbreakable' encryption unveiled....

    Perfect secrecy has come a step closer with the launch of the world's first computer network protected by unbreakable quantum encryption at a scientific conference in Vienna.

    The network connects six locations across Vienna and in the nearby town of St Poelten, using 200 km of standard commercial fibre optic cables.

    Quantum cryptography is completely different from the kinds of security schemes used on computer networks today.

    They only say it's unbreakable, but at the quantum level, you cannot tell if it's broken or not, plus all computers that use it must be kept in a box with a cat.
    A third party security audit is the IT equivalent of a colonoscopy. It's long, intrusive, very uncomfortable, and when it's done, you'll have seen things you really didn't want to see, and you'll never forget that you've had one.

      Jackalope, that is a MOST awesome question! There have been many claims to "unbreakable" encryption. No encryption is unbreakable. Difficult to break, perhaps. but not impossible. Even DNA encryption (mentioned a few years ago) is not unbreakable. Given the facts of the DNA sequence (and unfortunately law enforcement and the .mil have made gaining this information easier), one only needs to devolve the password (if any is required).

      Quantum physics has always fascinated me. And the idea of quantum crypto keys is right sexy. Theoretically, those can also be broken. Given the facts in the key, one does not have to replicate the point in time the key is devolved, only the circumstances of the point in time that the key is devolved. If it is two point encryption (algorithm devolved from point in time and password) it would not be difficult to break. Three point encryption? Well, I will just have to cut off your finger. :-)

      But why are you even considering this? I suppose that one would only use something like this for Ub3er ultra secret squi33l sPy stuffs...or to secure one's horde of twinkies. :-D

      I am not a "hard" scientist and have not tested this, obviously; but boy! Would I love to!

        I seem to recall reading about 20 years ago in Popular Science that they (whomever they may be) was recording space noise to use as a key for encryption. I wonder where that project went to? I believe the reason for using space noise was they couldn't find anything more random.

          Simple. Nothing is truly random. Given time, computing power and AHAH moments, nothing is impossible to replicate. If you are interested, investigate NASA's work on repeated audio patterns from space noise.

            unbreakable = not understood yet

            Time + knowledge + tools = cracked (oops i meant to say hacked sorry) political correctness looms. A crude but effective hack would be physically breaking the link between the quantum servers. FOC is not indestructible buried or strung on a pole. Chainsaws and shovels are good for this. In time a more delicate hack should appear.

              Yes, completely unbreakable. Unfortunately, the password is "1234", the same as streaker69's luggage.

              It isn't random, it's the "other" AI trying to find an equal. What's the matter Val, didn't read Neuromancer?

                I'll have you know, I got new luggage since last year. My combination is now '12345'.

                  I'm sure that's what the Germans and Japanese thought during World War 2. Also what our Mediterranean Fleet thought during the Cold War. The Soviets had broken our code and pretty much knew every move they made.

                      As for the security on it I'm thinking:
                      Portable high powered passive ion microscope on the fiberwire.
                      Essentially looking at the photons and recording the sequence without disturbing the travel. Then playback and slowdown the frames and translate into binary, then start hashing away.
                      But, then again, I am very tired right now and can't think straight.

                        i had actually heard of someone (whom we all know and respect) in the UK who was using a radio tuned to a non-station placed within a Faraday cage to generate static as random as possible to seed crypto operations.

                        I wonder if that would be more or less replicable than the outer space solution. At this point, it all gets rather academic for me (and, quite turly, over my head as well) since the notion of breaking super strong crypto fascinates me but the math and computing power and just the general operations involved are beyond me, both in terms of my grasping the matter and in terms of something i'd ever actually have to / want to do.

DRM, low bit rate, etc... OiNK it existed because it filled a void of what people want."

                          that's an interesting idea for seeding as well, and if you really wanted to cause it to fluctuate even more in randomness you could put a variable voltage spark gap generator in the faraday cage as well. That would cause enough interference/noise on the radio to really make the seeding random.

                            If that were doable, it would defeat the point of quantum cryptography.

                            The whole point is that one can't observe the photons without disturbing them.


                            Also, whether the stream is truly random or not is a physics question, or perhaps a metaphysics question, but for the moment it is, as far as we can tell, an unreproducible stream.

                            So, unless I'm missing something here, it's effectively uncrackable, barring a monumental discovery in physics.
                            this discovery would have to be either
                            1) how to violate the uncertainty principle
                            2) how to reproduce a quantum random event, reliably.

                            Is there something important I'm missing here?
                            It's not stupid, it's advanced.

                              It has been long posited that one cannot observe photons in motion without disturbing their native state. Having said that, it would be interesting to attempt a passive capture and play with the results. You aren't missing anything. You are merely basing your hypothesis on what is already known. There is much that we don't yet know and perhaps shan't ever know. I still contend that nothing is truly random, just finding the patterns may be a challenge.
