    Abstract: In an embodiment, a system is provided in which the private key is managed in hardware and is not visible to software. The system may provide hardware support for public key generation, digital signature generation, encryption/decryption, and large random prime number generation without revealing the private key to software. The private key may thus be more secure than software-based versions. In an embodiment, the private key and the hardware that has access to the private key may be integrated onto the same semiconductor substrate as an integrated circuit (e.g. a system on a chip (SOC)). The private key may not be available outside of the integrated circuit, and thus a nefarious third party faces high hurdles in attempting to obtain the private key.

    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.

    Abstract: Some embodiments provide a method for a first device to join a group of related devices. The method receives input of a password for an account with a centralized entity and a code generated by a second device in the group. When the second device determines that the code input on the first device matches the generated code, the method receives an authentication code from the second device for authorizing the first device with the entity as a valid device for the account. The method uses the password and information regarding the first device to generate an application to the group. After sending the application to the second device, the method receives information from the second device that enables the first device to add itself to the group. The second device verifies the generated application, and the method uses the information received from the second device to join the group.

    Abstract: Some embodiments provide a method for a first device for joining a group of related devices. The method receives input of a password for authorization with a centralized entity. The method receives input of a code generated by a second device already established in the group of related devices. The method uses the password and the code to (i) join the group of related devices in order to synchronize user data with the devices in the group of related devices and (ii) authorize the first device with the centralized entity as a valid device for a particular account with the centralized entity.

    Abstract: Some embodiments provide a method for a first device that identifies definitions of different groups of devices, each of which is defined by a set of properties required for a device to be a member. The method monitors properties of the first device to determine when the device is eligible for membership in a group. When the first device is eligible for membership in a first group of which the device is not a member, the method sends an application for membership in the first group signed with at least a private key of the device to at least one other device that is a member of the first group. When the first device becomes ineligible for membership in a second group of which the first device is a member, the method removes the device from the second group and notifies other devices that are members of the second group.

    Abstract: Some embodiments provide, for a particular device in a set of related devices, a method for backing up data synchronized between the set of related devices. The method stores the backup data encrypted with a set of data encryption keys. The method also stores the set of data encryption keys encrypted with a master recovery key. The method also stores several copies of master recovery key data, each copy of the master recovery key data encrypted with a public key of a different one of the related devices. The backup data is only recoverable by accessing a private key of any one of the related devices.
