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 determining whether the hardware component is authorized to run on the product based at least in part on whether the trust anchor receives, from the hardware component, a response encrypted using the random value (K). The method further comprises allowing or preventing the hardware component from running on the product based on whether the hardware component is authorized to run on the product.
