To give a small update on this topic: we implemented a small application in ROS2 that can be found in https://github.com/ros2-for-arm/example. This application is using TrustZone support with Optee-OS to encrypt and decrypt ROS2 messages from the application level. As of now, this is not using the ARM DDS SecureLib (as this is still under development) but it gives a small example on how to use TrustZone+Optee-OS to secure messages by having security assets in a secure memory. --- [Visit Topic](https://discourse.ros.org/t/ros2-and-dds-security-enhancement-on-arm-platforms/3677/12) or reply to this email to respond.
