These are all from memory so there might be some flaws. GSM and CDMA are
battered, bruised and broken from a security standpoint. 3GSM (there are
actually multiple 3G standards but 3GSM is the major player right now) in
it's native mode appears to be secure, it uses a variation of a published
and analyzed cipher, but I don't believe the actual 3GSM algorithm has
received noticable public attention. The bigger weakness in 3GSM is that
all
implementations that I am aware of actually have a fallback mode to GSM,
and
while I haven't looked at the exact protocol, this type of fallback
behavior
has a history of problems (SSL makes a good example). Regardless, these
are
all only between handset and basestation, not from handset to handset,
there
are arguments on both sides of this, but it does provide a wiretapping
point
which may or may not matter.
