Abstract
In various embodiments, methods, devices and systems for securely generating, sealing, and restoring factory-generated calibration and provisioning data for an electronic device are described, in which calibration and provisioning data for an electronic device are generated in a distributed manner and stored on a storage system. The calibration data can be retrieved from the storage system during device assembly and finalized calibration and provisioning data for each electronic device can be stored to the storage system. In one embodiment, a sealing server, to attest to the authenticity of the factory-generated data, seals the finalized calibration data. In one embodiment, an electronic device can access a data store containing the factory-generated data and can update or restore calibration or provisioning data for the device from the data store.
