The 2TB tables are coming (will share it online over a 50Mbps connection

So the known plain text is a fixed length string, or can it differ dramatically.
If it is somewhat fixed we can ask the members to contribute their
known plain text into a database in order for others to use.

Not read far enough into GSM 04.08 I see :)

Hi,
Ok, i just ordered USRP1 + DBRX + Antenna with express shipping and i'm
seeing to retrieve a copy of the 2TB rainbow tables.
So i should be equiped to be able to run with both OpenBTS and Airprobe.
OpenBTS won't work without a RX/TX setup obviously ...
(You can extract the RX code and try
I agree with Peter. It is completely useless to waste time on old hardware.
But it'd make for dead cheap sniffer ...
There are many groups that try that without success, as each hardware was
done with physical limitations.
Really ? do you have any specific examples of failed attempt and

Besides, you gotta remember, that the USRP is a very expensive piece of kit,

See Sylvain's earlier post reply for a good explaination
But whether you use a USRP2, a USD 20,000 military SDR or a small custom
cheap board will not change the fact that somebody still needs to write good
demodulaton/decoding software. And any work spent on new hardware development
is not going to bring any progress to the project.

No need to apologize, I think you make a very good point.
The problem with regard to practical GSM A5 cracking is not that
hardware is too expensive or that you need to do your own custom
hardware.
The problem is that everybody wants a
As mentionned OpenBTS laurent's decomposition demod seems to be way
better than the current one (from the limited testing I did). Another
benefit is that you can exploit CUDA _a_lot_ for the first stage of a

How do you want people to contribute code to the airprobe project

It is quite possible even without hardware to test on. It's just not
as rewarding.

Hey all,
Just came across this board yesterday... Pretty amazing stuff tbh.
I've always taken a really active interest in anything cellular related,
however things went a bit stale about a year ago, and I found myself with
less and less time available.
But now I really want to get back into it

I've actually been thinking of ways this could be done...
Here's some random ideas:
- Try and arrange a deal with Ettus Research, in which we could purchase
the hardware at a cheaper price for academic based research.
- Go to 2600 meetings, and suggest starting up a ccc.de style work
