The special version of the BlackBerry Z10 is now selling for whopping $2,770. All that extra cash should make sure you and the person on the other end of the line are the only ones versed in the conversation.
The super-secure Z10 is a product of Secusmart GmbH, which as far as I’ve understood is happy to sell its gear to top German officials. These guys basically bundled a MicroSD card loaded with Secusmart’s proprietary software and hardware to offer 128-bit AES encryption, elliptic curve cryptography, and certificate-based authentication of call participants. That extra security, however, only works if the person you’re calling has the same level of protection.
