    Abstract: Techniques are disclosed relating to securely storing data in a computing device. In one embodiment, a computing device includes a secure circuit configured to maintain key bags for a plurality of users, each associated with a respective one of the plurality of users and including a first set of keys usable to decrypt a second set of encrypted keys for decrypting data associated with the respective user. The secure circuit is configured to receive an indication that an encrypted file of a first of the plurality of users is to be accessed and use a key in a key bag associated with the first user to decrypt an encrypted key of the second set of encrypted keys. The secure circuit is further configured to convey the decrypted key to a memory controller configured to decrypt the encrypted file upon retrieval from a memory.

    Abstract: Some embodiments provide convenient auto-authentication for user data on a primary device, while still providing a significant level of security, by taking advantage of existing security and cryptographic measures used to communicate with a secondary device. The primary device of some embodiments encrypts the user data on the primary device using a cryptographic key based on a set of keys received from the secondary device. In some embodiments, the primary device encrypts authentication data, or a local key generated from the authentication data, using a remote key received from the secondary device, and encrypts the user data with the local key. In some embodiments, the keys received from the secondary device are an existing set of keys for establishing an encrypted channel of communication for transmitting digital rights management (DRM) protected content according to a DRM protection scheme.

    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 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.
