ABSTRACT:
A trusted device, physically associated with a network appliance that does not include a CPU, communicates with at least one component of the appliance and is accessible via a network connection to the device for providing a signal indicative of a condition of the appliance. The appliance can be a storage box having bulk non-volatile memory storage locations. The component is an ASIC of a controller of the appliance. The trusted device acquires a true value of an integrity metric of the appliance which is reported by the trusted device to a challenger. The component then provides the root of trust for measurement. The trusted device provides the root of trust for reporting. In a RAID controller assembly, each RAID controller has its own trusted device.
