Abstract
A method is provided for updating identity data on devices. The method provides for acquiring a device comprising a component associated with a component identifier and having a One Time Programmable Key installed on the component, submitting the component identifier and the One Time Programmable Key to an External Trust Authority, receiving new identity data tied to the component identifier from the External Trust Authority that is encrypted with the One Time Programmable Key, loading the new identity data onto an Update Server, receiving a request at the Update Server from the device that requests new identity data, and providing the new identity data upon receipt of the request, upon which the device decrypts and installs the identity data using the One Time Programmable Key installed on the component within the device.
