As the Internet of Things (IoT) and Software-Defined Vehicles (SDV) expand, the need for hardware-level isolation has never been greater. ARM TrustZone technology provides the foundation by separating execution into a “Normal World” and a “Secure World”. However, the hardware is only as strong as the software running inside it. 

In the current cybersecurity landscape, most operating systems (OS) rely on “marketing trust”, a cycle of reactive testing followed by endless patching once vulnerabilities are discovered. But for mission-critical systems in Automotive, Aerospace, and Defense, finding bugs isn’t enough, you need to prove they cannot exist.
