Australian researchers have demonstrated a way to prove core software for mission-critical systems is safe.
The researchers this week said they can prove mathematically that code they have developed, designed to govern the safety and security of systems in aircraft and motor vehicles, is free of many classes of error.
Australia's Information and Communications Technology Centre of Excellence (Nicta), a private-sector research organization, this week announced the completion of the first formal machine-checked proof of a general-purpose operating-system kernel. The kernel is called the secure embedded L4 (seL4) microkernel.
