The greasing requires some kind of "obfuscation" or "encryption" of the packet type. Simple obfuscation would be to combine the packet type with some fields in the packet, and would not require any "key". Problem with that is that middleboxes will quickly learn the obfuscation algorithm, and then reverse it. So if we want to actually grease, we need to use some kind of key-driven encryption.
