How many suitable quasars are there? You'd be damn lucky if its a
cryptograhic strength number.
Now you might think there are limits to how many signals you can
listen to and that would be some protection, however you still have
brute force guess a signal, and probability of guessing the right

It sounds like encrypting $P$ by xoring it with random

Scientists have come up with a method for encrypting
messages using the internet objects, which emit signals
and are thought to be powered by DC

I think that we have the evidence. The security MD5 depends
heavily on a lot of nonlinearities in functions F,G,I and on
carries in arithmetic additions. Nonlinearities in F,G,I are
bitwise and very weak. Carries are much stronger, but the collision
