Abstract: Some embodiments of the subject technology provide a novel system for synchronizing content items among a group of peer devices. The content synchronizing system of some embodiments includes the group of peer devices and a set of one or more synchronizing servers communicatively connected with the peer devices through one or more networks. In some embodiments, the synchronizing system uses a star architecture, in which each peer device offloads its synchronization operations to the synchronizing server set. Without establishing a peer-to-peer communication with any other peer device, the particular peer device in these embodiments supplies an encrypted content item set along with the N−1 encryptions of a content key used to encrypt the content item set to the synchronizing server set so that this server set can distribute the encrypted content item set and an encrypted content key to each of the N−1 peer devices.
