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.
US-based aerospace and defence firm Boeing also unveiled its own Black phone - not to be confused with the Silent Circle and Geeksphone Blackphone - at MWC this week, but that appears to be restricted for sale only to government security agencies and defence industry customers, and therefore likely won't be available to the public through mobile operators or in retail shops.
