Abstract: Methods, apparatus, systems and articles of manufacture are disclosed to facilitate distributed data backup. An example apparatus includes a controller to detect a trigger event for a distributed backup mode; and, in response to detection of the trigger event, trigger the distributed backup mode. When in the distributed backup mode, the controller of the example apparatus is to identify one or more receiving devices within communication range of the apparatus available to receive a data backup from the apparatus. The example apparatus includes a data distributor to distribute data from the apparatus among the one or more receiving devices. The controller of the example apparatus is to confirm receipt of the distributed data by the one or more receiving devices.

Abstract: Methods, apparatus, and computer program products for generating a derivative key for an execution environment (EE) are described. An example of a method includes obtaining a device key by a key derivation circuit, obtaining a context string by the key derivation circuit from a one-time writable bit register (OWBR), generating the derivative key for a current EE by the key derivation circuit based on the device key and on the context string from the OWBR.
