Hardware Root of Trust a hardware-based foundation for security functions such as protected key storage and checks of boot integrity. [1]
Purpose
A root of trust is intended to anchor security operations in a component whose behavior is more tightly controlled than ordinary application software. Designs vary across embedded controllers, processors and dedicated security chips.
Boot and measurement
Some systems verify software components before execution; others measure components and provide evidence to a verifier. These mechanisms differ and should not be treated as interchangeable. [2]
Benefits and assumptions
Hardware-backed keys can make extraction more difficult, but effectiveness depends on correct provisioning, firmware configuration, lifecycle management and hardware threat models.
Physical AI use
Robots and industrial controllers may use protected identities to support updates, remote verification or device enrollment. Such mechanisms do not by themselves establish physical safety of the machine.
