The framework for securing a trillion devices

At Arm TechCon 2017, we announced a major program to improve IoT security, called Platform Security Architecture (PSA). PSA is a common framework aiming to provide a holistic approach to IoT security.

Learn everything you need to know about PSA with the resources below. These will be updated when new materials become available.

The TMSA is a starting point for assessing the security risk facing a selection of connected devices. From this research, the right level of security can be determined, and then functional requirements established to mitigate the threats.

Now available! Open Source Trusted Firmware-M

Arm wants to make security simpler and more cost effective, by making high quality reference code and documents accessible – as security becomes more complex, all developers need access to these resources.

We have released the first open source reference implementation firmware that conforms to the PSA specification, Trusted Firmware-M, at the end of March 2018.
