Hi,

Following on from the presentation and discussion on Ken's "Default Handles" proposal on 30 April, we have made some updates following the feedback and further implementation consideration. I (or Ken if he attends) can present an update on the proposal.

I also mentioned last time that there is some missing context for this proposal. We are working on an update for PSA-FF-M v1.1 that will provide an enhancement of the v1.0 'IPC model' for secure services, and also a 'Secure Function model' which is similar to the 'library model' of TF-M today. The objective is a single architecture that enables secure service developers to select the framework features required for the complexity of the service; and the framework implementation to be optimised for simple systems.

On Thursday, I would like to present an introduction to this PSA-FF-M v1.1 roadmap, and outline the steps that we think are required.

Regards, Andrew
