both sim_scan v2.01 and cardinal v68 could not get ki from simcard .
simcard , hardware , software and cable are ok because simcard reply to software request for ATR , IMSI and so on , but for KI there is no success .
Any idea for solving this problem ?
Thank you .
Hi!
Maybe Your simcard is comp128v2, wich has not been cracked yet.

you are right . I checked it with another software and it says the algorithm is comp128v2 .
Thank you , kmike84

How did you check it?
Which software said Comp128V2 , ?
Can you give more details please?

Woron_scan ver 1.07 performs a check if the last ten bits in the reply of GSM-Algo (Kc/SRES) are zeros or not. If not - then the card is DEFINITELY not comp128v1.

Hi,
I donīt understand.
But....
The COMP128 V2 have this bit to Zero. This only is valid to know if is a COMP128 v3 .... ŋ?

I've said what i've said - no more, no less (and nothing about v2 ;))
Yes - up to date (before the message by hfathollahi) it seemed to be impossible to distinguish between v1 and v2 otherwise than by performing a collision-based 2R-attack. Trying one or (better) - two pairs. If no collision found - it's very likely that the card is v2.
Hope that our dear friend hfathollahi will supply more info on the software which distinguishes between v1 and v2 without numerous runs of GSM-Algorithm.

Dear M8s
In fact I used xsim0.9 and its collision algorithm to find out Ki . it started the test , but after half an hour it gave a message that " the alogorithm inside the simcard is comp128v2 , but it can continue the collision test " . that's all .

Hi,
But I afraid you card is COMP128 v2. For the moment havenīt solution.
