Create a config something like.

{
  "permissions: [
     {
       "message_type": "mission_plan", 
       "accept_from": [ "noc-c2", "ori" ],
     },
     {
       "message_type": "acknowledgement",
       "accept_from": [ "noc-c2" ], 
       "where": [ 
         {
           "field": "payload.acknowledgement_type",
           "value": "mission_plan.pilot_approval"
         }
       ]
     }
  ]
}

On receiving messages process test against any configured permissions.
