    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.

    Abstract: A method of restoring confidential information items of a first device to a second device by using a set of servers. The method generates a public and private key pair and ties the private key to the hash of executable code of the servers at the time of generating the public and private keys. The method receives the encrypted confidential information items in a secure object which is encrypted with a user-specific key and the public key. The method only provides the confidential information to the second device when the second device provides the same user-specific key as the key that encrypts the secure object and the hash of the executable code of the servers at the time of accessing the private key to decrypt the secure object matches the hash of the executable code running on the servers at the time of generating the private key.

    Abstract: Some embodiments provide a program that synchronizes a keychain stored on a device with a set of other devices. The keychain includes a set of keychain items. The program receives (1) a list of keychain items for updating the keychain stored on the device and (2) data representing the keychain items specified in the list of keychain items. For each keychain item in the list of keychain items, the program updates the keychain stored on the device with the data that represents the keychain item.

    Abstract: Some embodiments provide, for a particular device in a set of related devices, a method for backing up data synchronized between the devices. The method receives a command to create a backup for a subset of data synchronized between a subset of the devices, which is a subset of all data synchronized between the devices. The method identifies the subset of synchronization data from the set of all synchronization data. The subset of synchronization data is tagged as pertaining to a particular set of criteria for synchronization between only the subset of devices. The method stores a backup of the subset of synchronization data in a backup storage encrypted in such a way that requires a recovery key associated with any one of the devices in the subset of devices to access the backup while preventing access to the backup with recovery keys of any of the other devices.

    Abstract: Some embodiments provide a program that provides data protection for a device when synchronizing a set of keychains stored on the device with a set of other devices. The program receives keychain data for synchronizing the set of keychains stored on the device with the set of other devices. The keychain data is specified as belonging to a protection domain. The program determines whether a set of conditions defined for the protection domain is satisfied. When the set of conditions is determined as satisfied, the program allows access to the keychain data in order to process the keychain data and synchronize the set of keychains stored on the device with the set of other devices.
