Abstract
Disclosed herein are systems, methods, and non-transitory computer-readable storage media for initiating data synchronization between devices. The method includes sending a host identifier and pairing record to a second device having a file system encrypted on a per file and on a per class basis for a set of classes, receiving from the second device a sync ticket containing encryption keys for the set of classes, and storing the sync ticket. Also disclosed is a method for synchronizing encrypted data between devices. This method includes receiving, at a first device having a file system encrypted on a per file and on a per class basis, a sync ticket containing encryption keys from a second device, retrieving an escrow key bag containing protection class keys, decrypting protection class keys based on the sync ticket, and synchronizing data with the second device based on the decrypted protection class keys.
