Abstract: A method of creating a root-of-trust (RoT) within a network fabric may include powering on a network interface card (NIC) baseboard management controller (BMC) (NIC BMC), booting up a NIC via the NIC BMC, obtaining an address for the NIC, verifying an identity of the NIC at a fabric trust identity server using a key obtained from a secure vault communicatively coupled to the NIC BMC, verifying with the fabric trust identity server a number of images of a host device residing in the NIC based at least in part on the identity of the NIC being verified, and instructing a platform BMC to boot up the host device based at least in part on the number of images of the host device being verified.
