I just saw the talk of Karsten Nohl at 28C3 and ask myself if it would be
possible to trigger a new session key (KC) after every e.g. Call,SMS,USSD
and silent SMS :) for next event.
I mean it seems that e.g. in O2 Network in germany the key never changes,
only when turning off and on the phone and after many events.
For O2 it maybe enough to reconnect to the network? I really would like to
get a somewhat secure GSM connection for my anchor mobile at home
(remotely controlled from the PC) for my nationwide homezone (BWHZ),
using osmocombb. :)
Has anyone a suggestion, idea?
