GSM Security

Now a days mobile has become an integral part of life & business. How secure is mobile traffic ? How secure is GSM ?

GSM security is flawed, the A5 (both A5/1 and A5/2) algorithm used in GSM has been broken, and there is a way to clone SIMs as well. The new A5/3 version of the encryption is somewhat more secure, but still breakable... In other words, GMS is protected agains casual eavesdroping, and that's as far as it goes.

Yep, I think Elliptic Curve Cryptography (ECC) on Public Key can minimize chances of security flaws, ECC can also impose access restrictions but still there is need of reverse-engineering to find more security bugs.

So all in all the advice is not to use Internet on your mobile for anything private?

That's OK - its so slow on my phone (and useless) I can't bare to use it for anything in the world!
