Abstract
The invention is part of the field of computer technology. It describes the architecture of a secure automation system and a method for safe autonomous operation of a technical apparatus, in particular a motor vehicle. The architecture disclosed herein solves the problem that any Byzantine error in one of the complex subsystems of a distributed real-time computer system, regardless of whether the error was triggered by a random hardware failure, a design error in the software or an intrusion, must be recognized and controlled in such a way that no security-relevant incident occurs. The architecture includes four largely independent subsystems which are arranged hierarchically and each form an isolated Fault-Containment Unit (FCU). At the top of the hierarchy is a secure subsystem, which executes simple software on fault-tolerant hardware. The other three subsystems are insecure because they contain complex software executed on non-fault-tolerant hardware.
