Hi Expert,

 

I want to disable the container authentication in my product. Below are the descriptions in processor's reference manual. There are no more details for this situations in the manual.

 

Can anyone help to explain these situations, or where can I find the explanation for them/

 

Thanks!

in the following life cycles without authentication:
