Google IoT Demo for Zephyr RTOS With TF-M Secured on Musca

In this demo, the Trusted Firmware M is providing the SPE and JWT sign, Zephyr is providing the NSPE and The Google IoT application is running on Zephyr using secure services from Trusted Firmware M.

  • Platform Security Architecture (PSA) is an IoI security framework being developed by Arm.
  • Trusted Firmware M (TF-M) is an open source project to provide PSA compliant secure firmware for M profile devices.
  • Zephyr is a Linux Foundation Collaboration Project to provide a small, scalable RTOS for connected, resource constrained device.
