Abstract
Embodiments of systems and methods for managing control of a security processor in a supply chain are described. In some embodiments, a security processor may include: a core; and a memory coupled to the core, the memory having program instructions stored thereon that, upon execution by the core, cause the security processor to: store a first public key usable to initiate a first secure boot process and unusable to initiate a second secure boot process; store a second public key usable to initiate the second secure boot process and unusable to initiate the first secure boot process; and in response to a first change of control or ownership of the security processor, render the first public key unusable to initiate the first secure boot process.
