GSM phones on 3G connections vulnerable


A research team from Israel found that the A5/3 cryptographic system used to secure the 3G connection in GSM phones are potentially vulnerable.

Does this mean your GSM phone on a 3G connection is more prone to security breach? Should you be really, really worried?


Global System for Mobile Communications (GSM) is the most widely used mobile phone protocol, with about 80% of all mobile phones using it worldwide. Some of the well-known networks providing GSM phones in the USA are AT&T and T-Mobile.
