Abstract
By using a symmetric key to encrypt mobile device data before transmitting the data to a backup location in a backup operation, access to the data, at the backup location, may be restricted. To facilitate later decryption of the backed up mobile device data, the mobile device may also transmit the symmetric key to the off-device location. However, to limit use of the symmetric key, the mobile device may encrypt the symmetric key using authentication data, before transmitting the encrypted symmetric key to the backup location.
