Toshiba creates cryptographic scheme even the NSA can't break.

We need to create more encryption, the more encryption we have, the better our society will be!

Crap. I have all mine in a folder in /user/documents/thingsNSAshouldntlookat/jamesbond/

that's not good enough?

Try reverse psychology, put it in a folder "Hardcore homo midget porn"

NSA dosn't need to break it. They just need to threaten Toshiba enough to build a backdoor for them.

[Laize]

Good. I need new encryption for my porn. Apparently putting it in a folder on the desktop named "N64" wasn't a strong enough defense.

That's why you make it a HIDDEN folder. Honestly it's like you just discovered how to internet.

That's the most beautiful thing. There is no backdoor. Laws of physics and all that.

Oh, they have the internet on computers now?!

Yeah, they can just force them to give them the private key instead.

God dammit. Every now and then a Homer quote pops up that still makes me snort-laugh out of nowhere.

How long do you need your data to be secret? I'm pretty sure 256 bit AES will survive brute force for much much much much much longer than the building you're currently sitting in.

Well, you assume AES is secure, which we have no evidence to the contrary.

If you have to brute force the key, then you'll be sitting around well past the end of the universe and not even be anywhere close to the keyspace.

But your overall gist is correct.

Guys, lets get this straight: symmetric key encryption (private key) is unbreakable.

This doesn't mean that your data is safe because you Truecrypted it- anything from "camera watches you type password" to "tiny device reads your password" to "man hits you with bat until you tell password" are ways to attack this. But the algorithms are secure.

[Rukentuts]

No security is impenetrable. Doesn't anyone else remember Oracle's "unhackable" DB?

[Verain]

Yeah, they can just force them to give them the private key instead.

Or someone could compromise your fab for the source or destination to leak the key physically.


In any event, the advance is legit. But it doesn't do what the headline says any more than existing technology does. What it DOES offer is a solid engineering advance in this field.

Currently. It certainly won't stand forever as QC makes factoring large coprimes much faster.

I need to buy some toshiba stock.

Sounds like the tech's pretty limited.

What should be more interesting is the other side of the coin; quantum computing itself. If we crack that nut (and we're damn close), wave goodbye to standard encryption. The most complicated encryption methods we have, that would withstand brute force methods for longer than the heat-death of the universe, would fall very quickly before a quantum computer, due to the same concepts.

Technically by definition quantum computers can't work as a stable system. The only way it works is if you isolate the system so it can't be observed. Assuming you can pull that off and still pull calculations out, you have no means to ascertain those calculations have any degree of integrity unless you double check them with a known system that you have some heavy degree of confidence in. To top it off the concept in and of itself is an engineering nightmare, debugging and troubleshooting doesn't exist for a quantum computer, because there is no bookkeeping for the intermediate steps from input to output. So when something does go wrong, you can only say it went wrong, you can never even guess as to why.

I remember almost a decade ago first coming across the idea and thought it'd be pretty cool, but, yeah, just like entanglements, while cool in concept and enabling sci-fi writers to go nuts, in actual practically physics says you can't use this for anything super cool or practical. That is, so long as the quantum model holds, the moment its broken (and most people are pretty certain that while it works, it's a model of convenience and it only happens to work very well, like Newton's methods all the way up to the atomic scale) there may be a means to apply these things in fun methods.

So? If this became common usage they would just have to resort to old school cracking, as in always attack the weakest link. If the math is no longer the weakest then that means that it's YOU. So instead you'll be locked in a basement with some scarey looking people that will do unspeakable things to you until you tell them your password or what they want to know. Take your pick ...

Concidering people cant even manage to install and use PGP properly I wouldn't really put this high on the list over things to worry about if I was the NSA.

I'm talking about breaking RSA, not quantum cryptography. RSA is absolutely crackable, its just computationally unfeasible for now.

There's few good hentai sites for streaming. Hence, I download.

I was so disappointed when I found out the D-Wave 'Quantum Computer' wasn't actually a complete quantum computer. Even so, it's a good sign we're headed in the right direction!

What are you going to do when your internet connection is down? You've got to be prepared, man.
