I'm no expert, so take below with a grain of salt - there may be other ways to accomplish this I don't know about!
If this is a "CUSTOM_VIEW" tile, you could implement the desired security on your applications end. The Jive tile view is just an endpoint that can be used to load additional data. You can read any further request made your system from Jive, and allow/deny accordingly.
Security from Config Strings
I'd just validate the config when you read it out from jive.tile.onOpen. If it's not what is expected - reject.
