Master encryption keys

The BlackBerry® Enterprise Server and the BlackBerry device each store a copy of the unique master encryption key of the BlackBerry device.

When you activate a BlackBerry device over the wireless network, the BlackBerry Enterprise Server and BlackBerry device use an authenticated link to communicate the value of the master encryption key.

For a user to send and receive messages on the BlackBerry device, the BlackBerry Enterprise Server and BlackBerry device must store matching copies of the master encryption key of the BlackBerry device. If the stored keys do not match, the following actions occur:
  • BlackBerry Enterprise Server and BlackBerry device delete messages that they receive from each other because they cannot decrypt them
  • BlackBerry device requires the user to generate a new master encryption key
