: Attacking phone privacy
: Axon July 28, 2013, 12:45:03 AM

Abstract.
GSM’s encryption function for call and SMS privacy, A5/1, can be broken in seconds with 2TB of fast storage and two graphics cards. The attack combines several time-memory trade-off techniques and exploits the relatively small effective key size of 61 bits.
