You can't just give the burst bits ... you want the bits of the A5 key stream (which are the XOR of the ciphered burst bits and what you guessed the unciphered bits are). > I have read the following link as well > http://srlabs.de/uncategorized/airprobe-how-to/ Read this to know how to guess plain text : http://lists.lists.reflextor.com/pipermail/a51/2010-July/000804.html If you don't understand it, read the GSM 05.xx specifications until you do. > It takes me around 8 minutes to crack a burst Wow ... given it takes up to 8-12 bursts to get the key, you're looking at an hour or so ... On good HW (4 disks + GPU) that should be closer to 40 sec by burst.
