I guess it was only a matter of time, but researches managed to crack RSA - by listening to a computer while it is decrypting the data.
You could use a phone near a laptop to crack the RSA.....welp

Oh no...

It's not like you couldn't already brute-force them...

* pimathbrainiac converts to [insert more secure type here (IIRC, there's one that creates a new key every time a decryption hapens)]

IIRC something called EEC is more secure.

Keep in mind they have only got this working on two very specific laptop models.

are you thinking of ECDSA? and yeah, if you aren't using it yet, you should definitely start.

What I wish is that we find ways to crack the TI-Nspire RSA keys faster. But then, TI will have switched to something else long ago.

Hehe, the NSA is everywhere

You have less to worry about than me, Soru. I'm living in the US

An attack like this would not help for the Nspire, because the private keys are never present on the calculator in the first place.
