Abstract
A system and method of securing and virtualizing firmware trusted platform modules (TPMs) for virtualizing a hardware security module (HSM) for a host within a network fabric is provided. The system and method include operably coupling a set of components associated with a host comprising a data processing unit (DPU) secure vault and a firmware trusted platform module (TPM). The firmware TPM is configured as a virtual firmware TPM. The DPU secure vault secures the virtual firmware TPM into one or more virtual firmware TPMs based on one or more partitions configured with the DPU secure vault. A virtual TPM manager communicatively coupled to the DPU secure vault manages one or more virtual TPMs for hosting a set of Virtual Machines (VMs) or Containers.
