What happens to work data on the tablet when it is
connected to a smartphone that deletes all smartphone
data
When a BlackBerry smartphone that is connected to a BlackBerry PlayBook tablet deletes all smartphone data, the
smartphone deletes its copy of the BlackBerry Bridge work key and the Bluetooth connection to the tablet closes.
The tablet locks all work applications and deletes its copy of the BlackBerry Bridge work key, which is stored only
in RAM.
The tablet encrypts all work data with keys that are encrypted using the BlackBerry Bridge work key. When the
Bluetooth connection closes and the smartphone and tablet delete their copies of the BlackBerry Bridge work key,
the keys that encrypt the work data cannot be decrypted so the work data cannot be decrypted.
The smartphone is designed to delete all smartphone data from memory when any of the following events occurs:
•
The user clicks Security Wipe in the security options on the smartphone.
•
The user types the smartphone password incorrectly more times than the Set Maximum Password Attempts IT
policy rule or the password option on the smartphone permits. The default value is ten attempts.
•
The user runs the application loader tool and types the smartphone password incorrectly more times than the
Set Maximum Password Attempts IT policy rule permits.
