Hello,
I was reading about tethering security when I came across this article
in this link on the net.
http://www.bit-tech.net/news/2008/02/25/gsm_encryption_broken/1
An important part of the text is reproduced below.
"GSM encryption comes in four flavours: A5/0 is no encryption at all,
and is the standard for GSM devices shipped to countries the
distributors don't like all that much; A5/1 is the fairly robust
'default' encryption implementation used in the EU and the USA; A5/2 is
a weakened version of A5/1 offered to countries the distributors have no
strong feelings about but which the government may want to keep its eye
on; A5/3 is a newcomer to the scene, offering a more robust scheme than
A5/1 but currently not implemented for anyone who doesn't work for a
three-letter-agency."
I am curious to know, what security do we use in India? I could not get
exact details on the net. Is the security of GSM equipment pre-set by
foreign manufacturers (read: their Govts.) or do we as Indians have some
say to modify it?
