>          Issue Type: Sub-task
>          Components: mrv2, security
>    Affects Versions: 0.23.0
>            Reporter: Vinod Kumar Vavilapalli

> 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.
