Hello everybody,

 

I'm trying to make a testbed for EAP-SIM with freeradius to authenticate on a WLAN network.

it works well thanks to the patch provided by seek-for-android : you can see the details here :

but you need to store IMSI, RAND, SRES, KC in a flat file as by default, we don't have the Ki of SIM cards

and don't have a HLR so we need to precalculate these values.

 

For our testbed, we're using some MagicSIM we've programmed with our own Ki.

So I wonder if anybody has already done some integration of freeradius with openbsc HLR to do EAP-SIM ?

 

Or is there a tool to calculate the triplets (RAND, SRES, KC) with input the IMSI (and Ki stored in the database) ?
If not, could someone points me where to start to write my own tool ? I don't think pysim can do it...

 

I found an entry about A3/A8 authentication here

     int get_authtuple_by_subscr(struct gsm_auth_tuple *atuple, struct gsm_subscriber *subscr) 
...but I want to calculate gsm_auth_tuple, not retreive it from the database...

 

 

Thanks for any information :)
