Depends how its set up. So long as it’s fully independent and disconnected from existing digital infrastructure it should be safer. It could be as simple as explosives hard-wired with a buried line running up into some bunker up in the mountains.
That’s what you have to do of you don’t want the invaders to get the tech. If you brick the processors they still have the machines. I’m not sure what the secret sauce is in this case, but china has a reputation of reverse engineering things in spite of foreign laws. The best way to keep it from happening is to make sure they get no part of it.
Geopolitics aside, the technical architecture implementation of this mechanism is really interesting for me. I think over all, having extra ability to disable these systems would prevent US launching attacks against the plants — which could cause spill over local civilian injuries — but there’s just so many more things to consider.
Is it a dead-man switch style of setup, where if it doesn’t get authorization from HQ after some time, it will stop working? Or is it a kill switch style of setup, where they can remotely issue a command to stop operation? Because different vectors then come up depending on the securing method. For example: Dead-man switch might be tricked/overcame by turning back the clock, whereas kill switch might be circumvented by severing the network connection before the command could be issued (literally cut the underwater cables before they start the invasion).
How is the mechanism itself secured? If it is certificate based like everything else, then we’d have to worry about the certificate signing authority getting pressured into signing certificates by state backed actors.
Would really love to learn about the setup one day after all these is over, to learn about the thinkings that’s been done on such an important piece of … “infrastructure”?
The flip side of this is that hackers can brick the same machines…

By remotely I don’t think they meant a long RJ45 cable connected to nothing.
So this doesn’t look like a setup that can be fully secure.
Could even be completely fake and just to dissuade China from invading.
That would be clever.
Stuxnet would like to have a word
Note, I said safer, not completely safe. Even a hard line to a bunker simply needs someone to locate the line and activate it.
Completely safe does not and likely never will exist, as the history of human arms evolution should demonstrate.
Assuming it wasn’t shielded and knew you where near by couldn’t you just broadcast the code or what ever with enough power to cause the same effect?

Oh come on… this isn’t just a scrap metal press.
Sure. But a kill switch might warrant some additional investment. It’s not like your other features.
Assuming the kill switch is a real kill switch, and not just casually shutting things down in a way where they can easily be turned back on.
