Abstract
In one embodiment, a method to authenticate a hardware component, by a system, includes performing a verification process to determine whether the hardware component is authorized to run on the system. The hardware component comprises an electronic fuse storing a hash of a data package and a memory storing the data package, wherein the electronic fuse is configured to provide the hash to the memory. The verification process comprises transmitting a random value (K) to the hardware component to prompt the hardware component to sign a response. The verification process further comprises receiving a signed response containing the random value (K) and the data package, wherein the data package comprises a first serial number associated with the hardware component and a first system number associated with the system. The verification process further comprises decrypting the signed response to verify a value of the random value (K).
