Abstract: Technologies for secure offline activation of hardware features include a target computing device having a platform controller hub (PCH) including a converged security and manageability engine (CSME) and a number of in-field programmable fuses (IFPs). During assembly of the target computing device by an original equipment manufacturer (OEM), the CSME is provided a list of hardware features to be activated. The CSME configures the IFPs to enable the requested features, generates a digital receipt including the activated features and a unique device ID, and signs the receipt using a unique device key. Signed receipts may be periodically submitted to a vendor computing device, which verifies the signed receipts, extracts the active feature list, and bills the OEM for activated features of the PCHs. The vendor computing device may bill the OEM a maximum price for PCHs for which there is no associated signed receipt. Other embodiments are described and claimed.
