Anyone can give an idea on cloning a comp128v1 SIM card with strong Ki
 
Hi,
I have some comp128v1 cards with "strong Ki" and anticlone function, "strong Ki" have less than 5 pairs of collisions and these SIM can recognize the collisions. If someone send a collision RND to SIM card, SIM card will use a fake Ki instead of real Ki to do comp128v1 algorithm.
So I can't get any two bytes of Ki by 2R attack, then I can't use 3R,4R,5R......
Is there any solution to clone these cards?

rgds,
Roy Windsor
