GSM Encryption Broken?

hi normally love love your stuff …. but

this is hardly a crack/exploit

are they going to give away the table if not then to replicate you need at least two motivated geniuses a huge bunch of FPGAs nad several years to replicate their learning and then three more momths to reiterate the table

oh yeah and then you need 30 mins and 2TB of storage and an FPGA to crack one GSM device where calls last perhaps a minute or so

what am i missing?

I guess the big lesson here is that it’s possible, and that it’s getting far easier by the moment.

What takes a fairly substantial amount of equipment now will be a joke in 2 years, and the question is whether or not the industry is ready to have people sniffing phone conversations out of the air and posting them online.

I don’t think they planned on it happening so soon, and I don’t think they’re ready.

But I agree it’s not the end of the world — just interesting.

If you can record the calls and crack them at your leisure, then it doesn’t matter if it takes 30 minutes.

But, this is only A5/1, not A5/2 or A5/3.
