With the introduction of TrustZone® technology, the memory and peripheral control units in the microcontroller can be set into a secure area (Secure world) and a non-secure area (Non-secure world), which can realize data protection, firmware update and Security of program operation. In addition, thanks to the TrustZone technology of the Armv8-M architecture, the design of switching between the safe zone and the non-safe zone is realized by hardware, which not only accelerates the conversion, but also consumes more power efficiently.


Nuvoton Secure Microcontroller Platform (NuSMP) supporting Arm® PSA


The Platform Security Architecture (PSA) launched by Arm® is a complete system, from threat model analysis, security analysis, to hardware and firmware architecture specifications and open source firmware reference designs. PSA is Arm®'s solution to the security of the IoT ecosystem. It provides basic design principles and more efficient ways to build safer IoT devices.
