After a long hiatus of over 5 months (in which time I started working for an awesome company called AdMob), I thought of restarting the blog after reading an interesting article about decrypting voice signals over the air. If channel hopping were the whole source of trust in GSM voice security, it was just a matter of time before the same was broken. Now, it will be interesting to see how more security features are added and if they will stand the test.
"If the GSM Association's excuse for bad crypto is there is another security feature we rely on much more, then of course, we'll break that, too." :)
