Earlier today, BlackBerry announced the acquisition of Secusmart — a company that provides high-security voice and data encryption and anti-eavesdropping solutions for organizations and enterprises. The addition of Secusmart will bring this encryption to BlackBerry devices, allowing users to make totally encrypted voice calls from their mobile devices.

During the BlackBerry Security Summit in NYC, we got a quick demo of Secusmart in action using a BlackBerry Z30 and BlackBerry Q10. Inside the devices is a special smart-chip microSD card that allows for the encrypted calls to work, and users enter a password on both ends when initiating and receiving a call.

The calls run through the standard BlackBerry 10 dialer, a user just needs to choose to make a secure call. After entering a password, the call is initiated. When connected, the call will show that it's secure on the phone screen.
