3. Securing an electronic hardware architecture
At hardware architecture level, the main failure is linked to the emission of an erroneous output. There are two possibilities:
wrongly issuing a permissive exit, which causes a safety problem (e.g. turning a traffic light green and wrongly authorizing the passage of a vehicle);
wrongly issuing a restrictive output, resulting in an availability problem (e.g. rail convoys at a standstill).
Depending on the impact of the absence of output, it is possible to define two families of systems:
systems with integrity; there must be no erroneous output (wrong data or correct data at an incorrect time, etc.). Systems with integrity are systems where the process is irreversible (e.g. banking transactions). For this kind of system, it's...
