Unhackable ?

[Zede]

BBC NEWS | Science & Environment | 'Unbreakable' encryption unveiled

William Gibsons near future cyberpunk world involved lots of hacking, please dont tell me the games up ?

I wondering via some specialist hardware it can indeed by decrypted, one can only hope so, for the sake of good sci-fi novels !

"quantum encryption"

Read that.. See you in 100+ years while I attempt to break it.

[kirennia]

It's only a matter of time before quantum computing comes to light (if it's ever proven possible to do...which, using theories of quantum teleportation could mean more things altogether...) and indeed, the basis of it shows that potentially unbreakable pass keys can be created but there are other interesting parts about it.

The interesting and also worrying part of it is that quantum mechanics allow for theoretically instantaneous results because of the way all atoms in the world act on each other. Basically, without going into it too much, when the first functioning quantum computer comes out, all other passkeys in the world, it doesn't matter what encryption you use, how many keys or whatever, all of it can be hacked in stupidly small amounts of time. With a 32k quantum processor (very overkill) it's theoretically possible to hack every single password ever used on the internet simultaneously in under 10 seconds.....

If this becomes a government only system when it comes out, well I guess it's just another big brother step really isn't it. I'd like to look into where the companies funding is coming from for this research and whether upon its creation it's going to end up being patented away to be used by only a select few. My faith in human nature is kinda low at the moment

kirennia, does this go to show determinism is more plausible than free will then?

because of the way all atoms in the world act on each

Quantum cryptography is unbreakable in as much as you can't intercept an encrypted message. One aspect of quantum physics is that when you measure something you change it. If somebody tries to intercept the message you will know about it.

You will still be able to hack into the users computer etc just not read messages once they have been sent. It will probably be possible to jam messages sent this way forcing people to use less secure methods.

They are not mutually exclusive terms.

Don't want to derail the topic as it's quite an interesting one but I have to respond to this...

I beleive more so in determinism then free will by quite a way. As sad as it sounds, as I beleive in no God (not saying it's not possible, just I think if there was one he should have shown himself by now) as such, with the way I look at life I think it's more of an inevitability that I beleive in that pre-determinism then free will.

I presume this is with regards to the other thread I posted in about the people shouting to the guy who commited suicide. I still think they shouldn't of done it; my argument there is that I'm still not going to put forward that way of thinking into real life circumstances because if I did, it'd by default void me of any emotion I feel towards a situation. As such, even with the other inevitability of thinking that way being that there is no such thing as good or evil acts, I still wouldn't want to be what I've got put into my brain as being the 'bad' person. There is afterall, still a chance that beleiving we have no choices in life is in fact wrong.

There is also the way of thinking that if every action we ever take is pre-determined, every act anyonelse we've ever met is also pre-determined, and everyone they've ever met etc etc so every action in the world is interlinked. So whether by fluke or by pre-determined action, the post made would still be heard by some people and maybe effect their actions in the future should they ever be in the same circumstance...or anyone they ever meet etc etc... Positive thoughts can still go a long way

Indeed A good way of looking at it is to relate it to wind. In order for you to try and measure how fast the wind is outside, you stick your hand out to test it. By sticking your hand out, you're changing the course of that portion of the wind. Relating back to sending data, by doing that, you corrupt the signal thus the receiver knows someone is trying to tap in. It's all done according to the spin on electrons (trying to examine the spin on an electron will in turn change that very spins direction) but the basics are the same... ish

I need bed... hope this made a bit of sense anyway.

Weren't you the one who cried wolf about people derailing threads? Or is it just YOUR threads that matter?

prove it.
untill then, i can make my own opinnion on the facts available.

no actually if you cared to read the thread fully you would see that it was about taking things offtopic that went against the Coc thereby getting a thread closed because it was then against the rules.

id hardly say its offtopic since kirennia mentioned something that atoms effect other atoms all over the world, which is basically saying their act is predetermined by something else. asking if this goes in favour of determinism is inline with the post.

Aye, but it wasn't what your initial whine was about. Since, irony delivers here

[Overdriven]

I actually agree with kirennia on this. Free-will isn't free. It's determined.

Based on a set of previous and current actions.

I do something now, there will be a pre-determined action/reaction. With everything, even if I don't know about it yet. (I'm slowly picking up on it, though, I already knew.. I just didn't know I knew it)

Could also look into Karma aswell.. in a odd way.

[old.Tohtori]

The one thing putting a big "no" into the pre-determination is that there had to be a single one decicion, event, or some such that produced the chain reaction of actions/reactions. And that had to be a non-reaction.

Otherwise, free-will or simple determined will, is completely possible either way.

Good idea.

Is it true that the FH servers use mice instead of software to block out hackers ?

I thought they just cloned a bunch of laddeys and paid them in crappy techno music!
