EFFICIENT HARDWARE TRUST VERIFICATION IN DATA COMMUNICATION SYSTEMS THAT COMPRISE NETWORK INTERFACE CARDS, CENTRAL PROCESSING UNITS, AND DATA MEMORY BUFFERS

A data communication system comprises a Network Interface Card (NIC), Central Processing Unit (CPU), and Data Memory Buffer (DMB) to efficiently verify hardware-trust. The NIC, CPU, and DMB execute boot-up software, and in response, the NIC, CPU, and DMB execute hardware-trust software to assert control over their Application Programming Interfaces (APIs). The NIC, CPU, and DMB receive and hash hardware-trust data with their physically-embedded hardware-trust codes to generate hardware-trust results. The NIC, CPU, and DMB transfer their hardware-trust results for hardware-trust validation. The CPU may execute Network Function Virtualization Virtual Network Functions (NFV VNFs) for Software Defined Networks (SDNs).
