- inactive, on 10/08/2008, -20/+120Oh please. Every year another "unbreakable" security system is launched, and is broken within weeks publicly, possibly within hours inside the NSA. Given enough time or resources, and any code can be broken.
- SHv2, on 10/09/2008, -7/+65just like titanic was "unsinkable"
- kinthiri, on 10/09/2008, -2/+55Quantum cryptography is unbreakable because if any 3rd party views it that does not have the credentials and is not the intended recipient, the simple viewing of the encrypted data by that third party changes that data such that even the intended recipient can't decrypt it. Thus they know that there is a 3rd party viewing the stream. Effectively the data self destructs if anyone attempts to intercept it or decrypt it. This is not a new phenomenon.
What is new is that its being used commercially. It had previously been used experimentally by the military in association with researchers, but this is the first time its been brought to life outside test environments and is available commercially.
The nature of quantum mechanics makes this truly unbreakable. You couldn't even factor this using your own quantum computer, if you could even get one with enough qbits. - thelif, on 10/09/2008, -4/+52What if it's so unbreakable, the encrypter can't decrypt it?
jk...? - hauntedchippy, on 10/09/2008, -1/+41The whole hype about quantum cryptography is that it has been shown mathematically that it is impossible to crack. This is no ordinary code.

One-time pad. - halohunter, on 10/09/2008, -0/+27If it's really uncrackable, the NSA will just secretly put in a backdoor.
- aaron552, on 10/09/2008, -2/+26The nature of quantum encryption is such that if the transmission is intercepted, then both ends know. They can immediately renegotiate a key if this happens. In addition, unless the interceptor knows the key, it cannot retrieve any data - diagonally polarised photons cannot be read correctly with a vertically polarised filter and vice versa, so all it will see is random gibberish that *is* indecipherable, since the data has effectively been destroyed.

@stbutler
Unless the fundamental laws of the universe we live in are conspiring against you!! - Teh1337Pirate, on 10/09/2008, -0/+20If you build it, nerds will come
- awesometastic1, on 10/10/2008, -0/+19so what your saying is all crackers have to do is constantly "view" the messages and they can freeze any communication along these lines by auto-scrambling the messages?
pfffsh messing with communications just got waaaay easier. - Laminarcissus, on 10/10/2008, -2/+16We have not broken this code, and we have grown frustrated and given up trying.
In fact, there are very few codes we know how to break, so please feel comfortable using any encryption you like for your most secret messages sent over telephones or radio.
-- The NSA - CCB0x45, on 10/10/2008, -2/+16One time pads are easily broken. You just have to find one of the padholders and knock them out and take it.
Now rot13, unbreakable! - TSK05, on 10/10/2008, -1/+15Good thing it is quantum cryptography then.
- tomz17, on 10/10/2008, -1/+14@alarcade
You would... but the social engineering attack vector ALWAYS exists. By your reasoning, there's no reason to patch computers, or lock down networks because you can always just social engineer to get what you are looking for... BS...
This technology effectively locks down the wire and completely prevents snooping by exploiting some fundamental laws of how our universe works! - inactive, on 10/08/2008, -5/+17This should be interesting.

If you are using quantum encryption you are certainly also going to use a random number generator based on quantum randomness such as radioactive decay ( which is *truly* random ). Such truly random number generators are already in wide use. - forthex, on 10/09/2008, -2/+13So this means that instead of hex keys, Digg users will spam chemical formulas in protest?
- drtitanium0, on 10/10/2008, -5/+15Unbreakable sure, but can it run Crysis?
- FTLJohnson, on 10/10/2008, -1/+11I figured the link to the crack would be in the comments already... hrm...
- JoshuaGross, on 10/10/2008, -0/+10I'm still on FAT32, you insensitive clod.
- jackelsmack, on 10/10/2008, -0/+9"a flaw in a common type of equipment used makes it possible to intercept messages without detection."
cracked... but only when it uses certain flawed equipment - chubbybubba, on 10/09/2008, -4/+13As long as humans are involved, a system no matter how secure, is always flawed.
(when our computers finally realize this, they will usher in a new age of perfection.) - tomz17, on 10/10/2008, -2/+11Agreed with @aaron552... a quantum computer just doesn't help you here!
- trogdoor, on 10/10/2008, -0/+8One time pad generated by radioactive decay.
- mtrip, on 10/10/2008, -0/+8Unless we're seriously wrong about our fundamental understanding of physics, this might actually be unbreakable.
- lilhelper, on 10/10/2008, -0/+7You literally cannot break quantum encryption..
That would go against the laws of quantum physics. - Ymeg, on 10/10/2008, -0/+7"WEP was once introduced as unbreakable."
It never was. - jwuster, on 10/10/2008, -0/+7Sorry pal, nothing will be foolproof in the face of human stupidity. Quantum cryptography can, however, secure the communication channel being used to send the data/key. The fact that humans are the input and output of any system makes it inherently insecure.
- alacarde, on 10/09/2008, -6/+13So instead of breaking the encryption why would you not put your efforts into obtaining the appropriate credentials through something like social engineering?
- ha3er0, on 06/16/2009, -3/+10FREE KEVIN MITNICK !!!!!
- hockeyplayer66, on 10/09/2008, -7/+14This just in...14 year old hacker cracks unbreakable encryption in 10 hours by creating Wii, I-phone, linux mod to his toaster.
- Mononuclear, on 10/10/2008, -5/+12Well it is wrong. A russian guy living in Sweden has proof of concept that breaks quantum encryption and is undetectable. I will try to find the link to the article but is has already been cracked.
http://technology.newscientist.com/article/dn14866 - milkmit, on 10/10/2008, -1/+7So wait... By nature of the design, any third party intercepting the signal will destroy it...but something is creating & transmitting this signal to begin with, so rather than just intercept it, why couldn't it be possible, theoretically, for the said third party to both intercept, dupe, and then continue transmission of the signal? A node set up as a forked splitter that reads a signal, makes note of it, and then sends that very same signal back along the path it was originally intended to the recipient.
I'm sure I'm missing something big here because that would be pretty basic stuff...which is why I ask the question. What, exactly, is preventing this from happening? - hornback, on 10/10/2008, -1/+7Did you even LOOK at the article you dense moron?
- Laminarcissus, on 10/10/2008, -1/+7In fact, it's so effective that I found your post to be indecipherable gibberish and my self-esteem has been effectively destroyed.
- trogdoor, on 10/10/2008, -0/+6Yes, and this technology gives the party that wants to communicate with you a way to transmit that one time pad while guaranteeing* that either you get it or nobody does.
*This guarantee is backed only by the fundamental workings of our universe. - inactive, on 10/10/2008, -3/+9*Tomorrow*
"Scientists unbreakable encryption system has been broken" - ToadLeg, on 10/10/2008, -1/+7http://en.wikipedia.org/wiki/Public-key_cryptograp ...
- PandoraMMXVIII, on 10/10/2008, -0/+5... but then wouldn't the computers be flawed? They were made by humans afterall.
- tyree731, on 10/10/2008, -0/+5Funny how people confuse "game copy protection" with "Pretty Good Privacy". these are two completely different things.
- milkmit, on 10/10/2008, -0/+5Huh?
- inactive, on 10/10/2008, -1/+6Advanced file encryption: "Delete"
- BlackJackJester, on 10/10/2008, -0/+5There already is an unbreakable encryption system - called one time pad. unbreakable so long as it's only used once.
- tomz17, on 10/10/2008, -1/+5That's really not how it works... go take a quantum class, and then get back to us!
- Ragecloak, on 10/10/2008, -0/+4supar hackar knows all and lafs at ur feable incripshuns!
- aramova, on 10/10/2008, -0/+4Uhm, He is free...
- tomz17, on 10/10/2008, -3/+7@skemez1
This is not an experiment... this is a production system that uses a fundamental physical principle that we understand damn well. One of the cool properties of the physics here is that this system really is "unbreakable" in the sense that successfully snooping would mean that one of the basic (and most exhaustively tested) principles of quantum mechanics is flat out wrong... (it isn't... as evidenced by the fact that the computer in front of you is operating)
The experiments have been run over the past century, and quantum theory is very well tested. In fact, many would argue that we understand it better than gravity! -
