Thanks for your comment. I'm not a native English specker, so it is helpful.

"TRUSTED" sounds meaningful for me, however, it is confusable with a concept
of "trusted procedure" in label-based MAC. It is not only SELinux,
Oracle's label
based security also uses this term to mean a procedure that switches user's
credential during its execution.

So, how about "CREDIBLE", instead of "TRUSTED"?

Thanks,
