Does not apply to GPRS

Does not apply to GPRS

Parent article: GSM encryption crack made public

Otherwise nice article, but I'd point out that GSM's packet radio service, GPRS (and therefore, though I haven't checked, I presume EDGE, which is an evolution of GPRS), uses different encryption so it isn't directly affeceted.

Here's a random Googled up source for that: http://www.kemt.fei.tuke.sk/predmety/KEMT414_AK/_material...

"GPRS encryption is done with a different family of algorithms: GEA0 (none), GEA1 (export), GEA2 (normal strength) and GEA3 (new, and effectively the same as A5/3). Note that the GEA1 and GEA2 algorithms do not have any relationship to the A5/1 and A5/2 algorithms, and they are not publicly known. There are no problems with any of these in the open literature."
