TLS in BBM
BlackBerry 10, iOS, Android, and Windows Phone devices send all data to each other through the BlackBerry Infrastructure over a TLS connection. In certain scenarios, BlackBerry OS devices also send data this way. TLS is a common web standard used across all major desktop and mobile web browsers for secure online banking and shopping. A TLS connection between a device and the BlackBerry Infrastructure is designed to protect BBM messages from eavesdropping or manipulation by an attacker.
