Confirm physical presence to a trusted platform module by physically connecting or disconnecting a hot-pluggable device

摘要

A compute node includes a motherboard having a trusted platform module, and also includes a port for selectively coupling a hot-pluggable device in communication with the motherboard. The compute node further includes a circuit coupled to the port for detecting a change in the physical connection of the hot-pluggable device to the port and a physical presence signal to the trusted platform module in response to detecting a change in the physical link of the hot-pluggable device with the connection. The change in physical connection of the hot-pluggable device to the port may include either physically connecting the hot-pluggable device to the port, physically detaching the hot-pluggable device from the port, or a combination thereof.
