Hi Glenn. As usual, you have a very interesting and creative idea. I
that I can prove the opposite of your claim either by Shannon information
or algorithmic information theory. I can fill in a few details if anyone
wants to see it.
Based on this I'll make the prediction that what we have here is really an
of ID. You constructed an interesting message and then worked backwards to get
the keyword. Am I right?
I think the following would be an interesting experiment to illustrate how
far off the
mark your example is. Suppose you and I and anyone else who wants to play
constructed 10 keys at random and then used them to decode the intercepted
message. Everyone then posts their decoded messages here and we'll see how
many are intelligible English sentences. The problem is that messages having
the statistical structure of English are in the low probability group for
generated sequences. The probability of getting *any* English message is
thus close to zero and approaches zero as the message length increases.
