Dear all,
I'am new in this mailing list.
I'am a PhD. student at the University Rovira i Virgili studying smart cards (SC). I would like to log transmitted apdus between reader and SC (like credit card, ID card, sim, etc).
I've recently bought a cheap sniffer (season interface) but I have problems with it, I lose data sniffing any smart card type (iso-7816).
I'm asking if your device (v1.1) is valid for this purpose. Note that v2 would be compatible with credit card sized smart cards (ID-1 and ID-000 smart card slots (with presence detection): so to be able to also sniff credit card sized smart cards).
However, I've read too that v1.1 is capable to read smart card with both modes (T=0 and T=1) with proper accessories (http://shop.sysmocom.de/products/fullsize-sim-fpc and http://shop.sysmocom.de/products/sim-adapter).
It is possible? With this device, I will log any smart card type?

actually the error is 98 62 which is invalid mac.
i have checked tha apdu and it is correct (as the 31.102 describes).
the MAC as i read is produced y the f1.
MAC = f1_K (SQN || RAND || AMF)
i think that the SQN i import is the problem then

Good evening.
I would like to ask some questions about osmo-sim-auth.
First of all i have installed it and i am capable of doing 2g
authentications with the parameters -r -s
However i face some problems with the 3g authentication. I have checked
my cards through windows and they are usim.
When i run the command
/./osmo-sim-auth.py -r 00000000000000000000000000000000 -a
ec9320c2c2120000c8b7de2a3449f1bd
/i get as response the following/
Traceback (most recent call last):
File "./osmo-sim-auth.py", line 114, in <module>
handle_usim(options, rand_bin, autn_bin)
File "./osmo-sim-auth.py", line 44, in handle_usim
if len(ret) == 1:
TypeError: object of type 'NoneType' has no len()
/I tried to find where the problem is and i have found that the problem
is possibly in the if statement in file USIM.py in line 296
( /if self.coms()[2][0] in (0x9F, 0x61):/)
i put before that line the following to see the value that is compared
in the if
/print self.coms()[2][0]
/and i get as response the number 152 which in hex is 98.
I also put a print 'aaaa' below the if statement to see if the print
will be executed.
Unfortunately the i didn't see the 'aaaa' message on the screen.
Do you know what should i do or where to search to fix this problem?
Thanks.
Hello,
I am interested in modifying the firmware of the simtrace device to
perform modifications on the data sent back to the phone. Is there any
documentation on how this can be done? I could not find any on the
website. I looked at the source a little bit but I am hoping someone
here can give me a jump-start on the best way to do this.
Thanks,
Sam W.
