Abstract
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, the Fault-Tolerant Decision 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. Experience has shown that it is difficult to find all design errors in a complex software system and to prevent an intrusion. The redundancy and diversity inherent in this architecture masks every error—even a Byzantine error—of an insecure subsystem in such a way that no safety-critical failure can occur.
