Abstract:
According to certain embodiments, a method comprises performing a posture assessment at a trust anchor in order to determine whether a hardware component is authorized to run on a product. Performing the posture assessment comprises determining a random value (K), encrypting the random value (K) using a long-term key associated with the hardware component in order to yield an encrypted value, communicating the encrypted value to the hardware component, and receiving, from the hardware component, a message encrypted using the random value (K). The message comprises an identifier associated with the hardware component. Performing the posture assessment further comprises determining whether the hardware component is authorized to run on the product based at least in part on the identifier associated with the hardware component. The method further comprises performing an action that depends on whether the hardware component is authorized to run on the product.
