[ros-users] [Discourse.ros.org] [Next Generation ROS] ROS2 and DDS Security enhancement on arm platforms

[Andrew Konecki]

@davidhuziji 

Just started reviewing the material.  Looks promising so far.  Just want to get some clarification on overall design.  

ARM DDS SecureLib defines an interface library but does not appear to be responsible for context / resource management.  For a prospective deployment context, it is possible there could exist different levels of applications attempting to leverage TrustZone, thus a form of resource management that can properly handle the context switching securely would need to be supported.  

I am assuming that this form of feature would likely be presented in the TEECLibrary existing in layer `EL1` in the `Block Diagram on Cortex-A Platforms` due to context awareness or is this something that is being attempted to be pushed into the `Secure World` `TEE OS`?
