A computing device is configured with a hardware root of trust ('HRoT'). The HRoT and a remote registration server exchange public keys while the device is in a trusted environment. The device is then locked by setting a lock status in the HRoT. The device can then be shipped to a recipient. When the device is powered on following transit, the HRoT pauses booting of the device. If a request to unlock the device is received, the HRoT provides an encrypted one-time password to the registration server. The registration server decrypts the one-time password and provides the decrypted one-time password to the HRoT. If the HRoT determines that one-time password received from the registration server is identical to the one-time password it generated, the HRoT sets the lock status of the device to unlocked and allows the device to boot.

Securing computing devices during transit

A firmware provides a setup browser that generates a setup menu. An internal forms representation of setup data for rendering the setup menu is converted to markup language (ML) setup data. The ML setup data is provided to an application that provides a GUI for defining a modified setup UI for the firmware. The application provides a graphical, drag-and-drop, WYSIWYG, UI through which a user can edit existing forms and controls, create new forms and controls, and specify default values and other properties. When a user modifies the setup menu using the application, customized ML setup data is generated that defines the modified setup UI. The customized ML setup data is used to create setup data that is stored in a firmware device for use by the setup browser with the internal format representation of setup data to render the modified setup UI.
