Abstract
According to certain embodiments, a method comprises receiving an encrypted value from a trust anchor. The encrypted value is received by a hardware component, and the encrypted value is associated with a posture assessment in which the trust anchor determines whether the hardware component is authorized to run on a product. The method further comprises obtaining a random value (K) based on decrypting the encrypted value. The decrypting uses a long-term key associated with the hardware component. The method further comprises communicating an encrypted response to the trust anchor. The encrypted response is encrypted using the random value (K). The encrypted response enables the trust anchor to determine whether the hardware component is authorized to run on the product.
