You're describing a broken and unusable cryptosystem. What you believe requires "substantial computation" to break today requires a consumer GPU tomorrow.

There is no minimizing the risk. Your concept is broken. It does not -- and cannot -- provide security of any use. And I don't care what the government thinks about it.

It’s just a brainstorming idea. There would be a key as well - the idea would require both the key and substantial computational power for exceptional access

Brainstorming ideas are meant to be thrown out. Attacking the idea respectfully is fine. It’s to help inspire other ideas.

Of course there’s a trade off involved. But whether it’s two party encryption or three party encryption with exceptional access none is perfectly secure anyway. There is major conflation of political ideologies with hardline technical viewpoints going on

Pre quantum algos have this shortcoming built in
