> Without security, it is impossible to completely avoid AMs faking resources. We can at the least make it as difficult as possible by using the same container tokens and the RM-NM shared key mechanism over unauthenticated RM-NM channel.
> In the minimum, this will avoid accidental bugs in AMs in unsecure mode.
