description The disclosed embodiments are related to securely updating a semiconductor device and in particular to a key management system. In one embodiment, a method is disclosed comprising storing a plurality of activation codes, each of the activation codes associated with a respective unique identifier (UID) of semiconductor device; receiving, over a network, a request to generate a new storage root key (SRK), the request including a response code and a requested UID; identifying a selected activation code from the plurality of activation codes based on the requested UID; generating the SHRSRK value using the response code and the selected activation code; associating the SHRSRK value with the requested UID and storing the SHRSRK value; and returning an acknowledgement in response to the request.
