Mobile Phone Communication Codes Cracked

The German scientist Karsten Nohl published his findings this week on the CCC (Chaos Communications Congress) in Berlin. The CCC is an annual hacking convention, which is being held in Berlin, Germany.
Normally, the GSM communication switches frequency regularly, and therefor it's hard to listen in, but if you can crack the frequency switching algorithm..... Which is exactly what Karsten Nohl and his team did.
They cracked the so-called stream-cipher A5/1 which protects the voice conversations, and published details off it on the CCC in Berlin.
