We have been kidding ourselves for so long now, with the 1024 bit RSA keys. We know well enough how TI did their evil deeds. We fought back and lost. TI has now since increased to 2048 bit since.
This has gone from impossible to impossible.
Even supercomputing servers will take an unpractical amount of time. Why then am I telling you that the Nspire may now be *possible* to be cracked?
Guys and lobsters, I present to you the QUANTUM COMPUTER:

If this product was to be put in a server, This just might be able to crack the uncrackable.
....The bad part is, how much will this thing cost us?! let alone 10 of these things! :crazy:
-
I'm sure it's been possible for a while...
feasible is a different matter :P
-
That simply looks expensive. I think we would seriously have better luck making our own calculators than that, it would cost 10x less and would be more profitable. (of course, neither are really practical, just saying yours is even less practical mostly due to $$$ constraints)
-
I found out that one of those things is $10,000,000 dollars. Thats not even including the area, or the labor to set one of those things up
-
expensive. We could make a lot of our own calcs for that money. I'll wait till these become affordable

20 years? :) by then, calculators will be more advanced than our computers we're chatting on right now. And, we'll have 65536-bit RSA keys :P
-
Well yeah, that would be possible with quantum computers. Of course, you can't have one just to crack 2048-bit keys. You should use it for something else too. Or just ask one of the companies who bought it to compute it for you.
-
How much would we have to pay them for the RSa cracking?
-

the only one in the world that bought it is lockheed martin.

I researched this a little and it seems to not be as good as it seems. They say you'd need at least a couple thousand qubits for quantum computers to be able to break 2048 but RSA. this one only has 128. The company that made this says they'll have a 1000+ qubit computer in a few years, but it seems that scientist are skeptical if its possible
-
yeah that's what I read too: http://spectrum.ieee.org/computing/hardware/loser-dwave-does-not-quantum-compute
-
This is the one I had read. http://www.scientificamerican.com/article.cfm?id=first-commercial-quantum-computer
-
OMG, A COMMERCIAL QUANTUM COMPUTER!
-
reading your link snake_x it sounds more like they are faking their quantum comp. That would be a great scheme. They have like 60 million in investments
-
If we start trying this, expect a new TI-Nspire line in 2 years that uses a 4096 key.
-
It won't be possible to try this for 2+ years unfortunately we need much more powerful quantum comps. It seems some people are skeptical about this one existing even
-
Yeah, it says it's the wrong kind of quantum computer to break security.
-
Sorry if I double post or repeat what someone's said earlier.
Anyway, while I don't doubt that it exists, I doubt that it's production ready or general purpose. I would be highly surprised if it could outperform even a half decent server. Quantum computers, to be honest, currently suck. You'd probably be better off trying to use a small server farm for the money than a single quantum computer.
-
I wonder if TI would just TELL you how to crack them if you paid them the amount it would take to purchase a quantum computer like that. >.>
-
I bought actually bought one of these and HIGHLY recommended it :w00t: ; however, all I could determine was that Scientology is the one true religion and some nonsense about the spirit of Christmas. I think it'll take a few more years of development before its usefulness kicks in.
-
the only one in the world that bought it is lockheed martin.
I'll drive up there and demand that they factor it.
-
Erm, what?
/me is confused about what scientology has to do with that...
-
Look at its size O_o

so you have 10 million dollars that you absolutely could not figure out what to spend it on so you bought a "quantum computer".. let alone the cost to house it, and to set it up :/
edit: and your the ceo of lockheed martin? They're the only ones who bought it..
-
Look at its size O_o

That thing would fill a freaking house

If we do try to crack it again, I'd suggest the Amazon Cloud. Its uberpowerful and extremely inexpensive to rent some real power.

Let's put it this way: Even if every computer on earth were to attack the problem simultaneously, it'd still probably take longer than you're likely to be alive. Also, "extremely" inexpensive" in this case is still bloody expensive.
-
It'S useless to crack the Nspire keys now:
1) The 84+ ones were cracked, and look what TI did now: the key factoring became useless on Boot 1.03.
2) The CX uses a 2048 bit key. I bet this was in response to people trying to factor the 1024 bit ones. The day we crack the CX key, TI will have moved to 8192 bytes RSA keys long ago.
-
True. But for a small amount of usage... $0.085 and for large, $0.68. We might be able to put a large (by that I mean quite small) dent in it.

You'd still be looking at billions of years to calculate it.
-
Exactly. But then, there is luck, however small that chance might be.
It may be worth trying at least.
-
It will still be a very small dent. We are better off trying to come up with a way to edit boot1 (safely) and remove the rsa protection entirely.
