We'll need way, way over 900142 computers to get it in a reasonable amount of time :P
Edit: Assuming Deep Thought's number is right, of course.

That's >9000!  :o

Anyway, is there anyway to simply wipe ALL of the data from the nspire? That way, you can at least start from scratch with a 3rd party OS, assuming that the nspire doesn't use firmware to store the certification routines.

It's in actual ROM, though, right?

I'm pretty sure you can erase ROM, although it wouldn't be available to anyone outside of an electronics lab. Never mind.

Bloody TI...

Well, technically you could, but that would require resetting and programming the flash chip manually. (I Think.  Don't quote me on this.)

Define "reasonable."
Also, this big of an RSA key has never been cracked, IIRC.  It might be something someone with lots of resources may want to help with outside the calculator world.

The people with "lots of resources" would be the ones who cracked the current record 768 bits.  Reasonable, meaning that in 20 years after a different calc comes out, we might find a factor.

A calc with a 16384-bit RSA. That would be fun :P

So, what's our best chance? Find a new algorithm?

Yep.  Which is why this topic is here.

Slightly off topic, but what if everyone hooked their Nspires up to their computers at night and the Nspires were used to hack the Nspire through distributed computing? :-P Although distributed factoring does seem to be the way to go.

This topic is two and a half years old and, as was explained earlier in the thread, completely infeasible. Please don't post in such old threads unless you have something significant to contribute. Locked.
