ARMv8-M TrustZone (TrustZone-M) gives Cortex-M23, Cortex-M33, Cortex-M35P and related MCUs a clean, hardware-enforced way to split a system into two execution environments: Secure world: the hardware root of trust, key material, security services, and the code that configures isolation. Non-secure world: the main RTOS and application logic, kept away from secrets by hardware boundaries. In […]
