I almost understood this. I think that means I'm learning something.
I liked the program obfuscation idea because in AI people want to run learning algorithms on machines that don't belong to them (like a farm) without giving away that sensitive info. This program obfuscation idea looks great for that. It reminded me of how people were saying that you could have a quantum computer privately compute your algorithms. I started wondering what else can you do with that and I thought maybe you could have routers allow you to run obfuscated programs, maybe a router was just a machine with a map allowing you to use your own routing algorithm. This way internet traffic could be harder to track and any logged info would have to be decrypted and no one could see where you came from or where you intend to go.
Then I started wondering about something else. Say routers weren't any different from today, is there anyway to prevent a man in the middle attack? How can you verify that there's no one in the middle catching, reading, and, relaying all your messages to your endpoint without relying on third party certificates/signatures?
I hope that someday someone will find the answer so that it can be implemented.
