How to foil the NSA and GCHQ with strong encryption

The most interesting device shown at Mobile World Congress (MWC) in Barcelona this week was the secure Blackphone developed by Silent Circle and Geeksphone.

The Blackphone features anonymous search, automatic disabling of non-trusted WiFi hotspots, and private texting, calling and file transfer capabilities. It’s available to the general public, and bundles additional security features that apparently go beyond the basic messaging security provided by Blackberry to enterprise customers in its Blackberry Messaging (BBM) service.
