Trusted Firmware M is an open source implementation of Platform Security Architecture(PSA) for Arm M profile processors. It was publicly launched in Linaro Connect HKG18. It offers- Trusted Boot – providing protection against malicious code injection on the device and secure firmware update Security isolation levels in the run-time – scope limiting system’s security critical resources and reducing the trusted code base Secure services – secure end points of the system providing service to other secure partitions and non-secure entities
This is an interactive session to deep dive into different technical aspects of TF-M and how these aspects bind to a connected device’s security model. An example use-case will also be presented to showcase how different components of the system firmware come together.
