Think of how noise is different from signal in Shannon's information theory. Messages that have information are distinguishable. Messages that have only noise content are indistinguishable, generally speaking.


A signal that looks like noise is one that carries the most information, i.e. is incompressible.

Interesting, so if one happens to not have the proper decoding key, how is it distinguished from noise?

Onward!

It isn't.   That's why encryption works.
