Hi all,

to better illustrate the relationships between the entities I created a diagram.

To summarize, a device is assumed to have one TEE only. Devices with multiple TEEs are not considered in scope.
The support of multiple Trusted Application Managers, TAMs, is envisioned.

To support a number of different applications from different service providers on a TEE there needs to be some form of isolation provided by the TEE so that the individual trusted apps (TAs) provided by different service providers do not access resources of each other. This isolation is accomplished through the security domain concept.

I am thinking about putting this diagram (in ASCII format) into the draft, if it is helpful.

Ciao
Hannes
