Yes, APO is more a driver component than a software. It also need to be
logo certified to run in production with the protected environment.
I have a question about the PE. How can you fully test an APO before the
certification process. Can you assume that, if the APO passes the HCK tests
it will work in production with the Protected Environment?
Best,
