Enabled by rapid improvements in CPU power. networks and software technology, the drive for automation and information now permeates everything from planning and control to interactive multimedia. Computers now control most of the systems with which we interact. Relying on computers to this degree fosters an urgent need for high-assurance systems (HAS). Such systems must be reliable, available, safe, secure and timely. HASs are state machines, in which nodes represent reachable system states and links represent state transitions. A system is a HAS if every reachable state is highly safe and if the probability of transitioning from a normal state to a faulty state is very low.
