Code breakers crack GSM cellphone encryption

[Olle Mulmo]

DCMA comes to mind: it could potentially make it a little harder to get
your hands on any mass market eavesdropping tool.

If you are terribly concerned about this, there are end-to-end encryption
phones on the market that are used by military and others already today.
Such systems come with a price tag though: As for me, the ordinary end
user, I just have be as careful with what I say or trust when communicating
over the phone as when I'm using email.

But that should have already been the case, had I thought things through,
and shouldn't come as a shock.

"Laughing my ass off."  Since when do governments care about patents? 
How would this help/harm them from exploiting it?   Not that
high-end LEOs haven't already had this capacity ---Biham et al
are only the first *open* researchers to reveal this.
