System-Wide Security for IoT Devices
TrustZone technology for Arm Cortex-M processors enables robust levels of protection at all cost points for IoT devices. The technology reduces the potential for attack by isolating the critical security firmware, assets and private information from the rest of the application. It provides the perfect starting point for establishing a device root of trust based on Platform Security Architecture (PSA) guidelines.
TrustZone provides a foundation for system-wide security and the creation of a trusted platform. Any part of the system can be designed as part of the secure world, including debug, peripherals, interrupts and memory.
TrustZone allows SoC designers to choose from a range of components that fulfil specific functions within the secure environment. TrustZone is supported by Corstone foundation IP, helping companies develop systems faster.
Developers can create TrustZone systems using familiar languages while maintaining the existing programmer’s model. Also, TrustZone is supported by a comprehensive ecosystem of RTOS, compiler, debug, and trace solutions.
