if one is to get really involved with this i think USRP would be a good investment(together with studying gnu radio) - they use gnu radio for a5 cracking in that chaos communications congres video too(i think its on thc.org somewhere)

I recall something around 1999 or 2000 reading GSM encryption already had been cracked...

I some books that do a good job of explaining the GSM air interface I need to dig those up but I don't think a software radio would be adequate its not a simple analog transmission but there are more than 1 error correcting algorithms and to write a GSM radio from scratch would be a challenge... probably you'd gain the knowledge needed to just about anything on GSM.

Anyways I wonder if these cards would be of any use: http://www.junghanns...ci_produkt.html

Hey all!
I am so happy to find a thread like this!
Anyways I am planning to develop my thesis on this area...
and possibly build an IMSI catcher within 3/ months. Possible? We will see!
:-)
I am based in the London, UK, and on our campus we have some good equipment we can use...

Possibly if someone wants to come over and work here I might be able to make you come down and work here.

Also I can get a budget for this project from the UNIV
which can help!

So where do we start?

John
