Abstract:
A method and an apparatus for configuring a key stored within a secure storage area (e.g., ROM) of a device including one of enabling and disabling the key according to a predetermined condition to execute a code image are described. The key may uniquely identify the device. The code image may be loaded from a provider satisfying a predetermined condition to set up at least one component of an operating environment of the device. Verification of the code image may be optional according to the configuration of the key. Secure execution of an unverified code image may be based on a configuration that disables the key.
