Hardware Root of Trust

Hardware Root of Trust (RoT) builds a chain of trust by authenticating all the firmware components before it runs, and permits only authenticated firmware to run and flash. Hardware RoT establishes a chain of trust by running the initial firmware code from immutable Internal Boot ROM (IBR) and this process authenticates and builds a chain of trust with succeeding software using this root of trust.
