Exactly. Anything that is deterministic can be compromised, even if that is something physical. The only thing you can do is make something so difficult/long/expensive to compromise that it't not worth it. This is the theory behind encryption, given enough time and/or computing power and encryption can be broken by brute force but making it require so much time and/or hardware to crack that the information would be useless by the time it is broken. You can't make a deterministic system unbreakable, only harder and harder to replicate the situation needed to break it.
- abecedarius 14y agoI guess you're bringing up determinism with the idea that if you can extract some information from a probe even if the system self-destructs, then given enough diverse probes you can extract everything. But the designer could refuse to send you an unlimited number of copies. I linked above to someone sketching a strategy to distribute limited DRMed designs worth trillions of dollars to unlock. He may be wrong, but it's enough to make me think the current state of the arms race need not hold forever.
- stevenameyer 14y agoIf the system has a state where the hardware reliably doesn't self-destruct, then that state can be replicated. From there probing can handle extracting the information needed and presumably some sort of interpreting of the information would be required to make it workable. Now I think this process has to be possible for any system (a reliable deterministic state has to be able to be replicated unless I am really missing something) but there a lot of ways to make replicating this process very difficult and unlikely to the point where I can't imagine anyone actually doing it, but it still is theoretically possible for someone to break it.
