Platform and method for remote attestation of a platform

A method comprising:

• configuring a processor of a processing system to operate in an isolated execution mode in a ring 0 operating mode, wherein the processor also supports one or more higher ring operating modes, as well as a non-isolated execution mode in at least the ring 0 operating mode;
• configuring the processing system to establish an isolated memory area in a random access memory (RAM) of the processing system and a non-isolated memory area in the RAM, wherein the processing system does not allow access to the isolated memory area if the processor is not in the isolated execution mode;
• loading at least one software module into the isolated memory area of the RAM while the processor is operating in the isolated execution mode;
• storing an audit log in the processing system, the audit log including data representing the software module loaded into the isolated memory area;
• retrieving the audit log in response to receiving an attestation request;
• and
• digitally signing the audit log to produce a digital signature in response to the attestation request.
