A Network Function Virtualization (NFV) Central Processing Unit (CPU) comprises a network core and a system core. The network core receives and validating hardware trust certificates from external circuitry that obtains the hardware trust certificates using a read-only hardware trust identifier that is physically-embedded in the external circuitry. The system core executing an NFV Virtual Network Function Component (VNFC) and generating VNFC data for the external circuitry. The system core calls an Application Programming Interface (API) for a hardware trusted communication with the external circuitry and transfers the VNFC data to the network core. In response to the API call, the network core transfers the VNFC data to the external circuitry when the network core successfully validates the hardware trust certificates from the external circuitry. The network core blocks the user data when the network core did not successfully validate the hardware trust certificates from the external circuitry.
