Title: The end of RSA?
Post by: Sorunome on December 20, 2013, 04:36:59 pm
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...

/me 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 (https://en.wikipedia.org/wiki/Elliptic_Curve_DSA)? 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.

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

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