John Sandford - Saturn Run

“How long will that take?” Crow asked.

“I can fab the box in a couple of hours,” Sandy said. “Compared to building a guitar, it’s nothing. If we get Elroy to work with Joe on the kill trigger switches… I don’t know, we should be done before midnight?”

Martinez nodded: “But we’ll have to hustle.”

The dinner briefing was quiet. Not much had changed. Santeros had confirmed the ship’s preparations for the Chinese, “although I’ll be pretty goddamned unhappy if you blow that tech.”

Sandy had finished the box and gave a brief description of the work: “Made out of steel, with a steel lock. It’ll have a bed of raw magnesium taken from Mayday flares. I didn’t want the magnesium to actually touch the memory modules, in case there might be some chemical reaction, so I fabbed a tray that sits inside the box, near the top, with individual grooves for each module. The tray’s made of non-reactive plastic, so the modules should be fine. That’s ready to go. Joe can tell you about his switches.”

Martinez said, “We created two electronic ignition circuits inside the magnesium bed—this is a very thin layer of the stuff, because it burns really hot, and we want it to burn out in a hurry. The circuit is battery-powered—two batteries sit inside the box, and either one can provide juice to the firing circuits. It’s got a radio link to a coded transceiver embedded in the wall of the room that would be almost impossible to find—it’s about the size of your little fingernail. Only two people know where it is, and the Chinese, even if they knew, would virtually have to tear the middle of the ship apart to get at it. Anyway, it’s a deadman circuit. If it doesn’t get a picosecond ping from at least one of the kill triggers each second, it’ll go off. Just in case the Chinese do manage to find the transceiver or otherwise isolate the box from a possible kill signal. We built three triggers for Admiral Fang-Castro to distribute as she wishes. We assume the actual holders of the triggers will be secret, trusted people known only to the admiral.”

“This all makes me very nervous,” Fang-Castro said. “Though it’s exactly what I asked for. How do we fire the switches, if we need to?”

He reached down into a briefcase and pulled out three gold slate styluses. “These actually work, of course. If you drop them, throw them, whatever, nothing happens. But if you look carefully at the middle of them, you’ll see a very faint line. That’s a cut point. You turn the two halves against each other, rotating them, it doesn’t matter which way, then just snap it in your hand. Like you were breaking a wooden pencil. It takes some effort, more than breaking a pencil, but nothing that would be a problem for any active person. No way that could be done accidentally, both the turn and the snap. Do it, and BOOM. The box blows.”

“Are they armed?” Barnes asked.

“Yeah, they’re functional, but the box isn’t. Not yet. I’ll arm that just before the Chinese come aboard. Once that’s done, it’s done.” He pushed the styluses across the table to Fang-Castro, who pulled them in, looked at them, and said, “God help us.”

Barnes asked, “What about the stuff in memory? The stuff we got through the I/O?”

“That’s a little easier,” Martinez said. “We suggest that the I/O material be sequestered in the main memory banks, at a location known only to Admiral Fang-Castro and her most-trusted people, and accessible only with a code. We should make it accessible through any terminal. If we hit a crisis point… somebody accesses the memory and hits delete.”

“I don’t see why that’s necessary,” Greenberg said. “The Chinese can’t make use of our data. We’ve been scrupulous about following the security protocols. Every bit of alien data that came in over the I/O is quantum-encrypted and the intermediate stores are scrubbed as soon as the backup’s been verified. We can’t even read our own records. The only copy of the decryption key is in Santeros’s hands. We’ve never seen it, it’s never been out of secure storage. Without it, the encryption’s unbreakable. The Chinese can’t get in. If there’s even the least chance of keeping or regaining control of the data, we can’t consider throwing away knowledge we won’t get for another hundred and fifty years.”

Crow shook his head. “That’s just it. As far as we know, the encryption’s NP-complete, secure even under quantum attack for aeons. But we might be wrong. The encryption could’ve been compromised from the beginning. Look what happened with the American atomic secrets during World War Two. The country built an entire top secret town out in New Mexico, and guarded it with the most paranoid military men you could imagine, and every bit of tech was stolen and delivered to the Russians. There are back doors into a lot of supposedly secure systems. The sabotage of the Nixon ’s power systems demonstrates that we can’t blindly rely on a belief that we’re impregnable.”

He looked around the room, then continued. “Even if we are… today… well, if I were the Chinese and I got my hands on that datastore, I would fund the mother of all Manhattan Project hacks. It might take me a century to figure a way in, but if there was any way in, I’d find it. That’s a long-term view. The Chinese are good at thinking long-term.”

Barnes said, “I kind of don’t like the whole ‘accessible from any terminal’ business. If I were the Chinese, and I took over the ship, I’d make sure that no terminals were accessible that they weren’t watching. Even if I had to shoot them out. I’d be a lot happier if we had the same kind of kill switch we’re using with the QSUs. Something that would send a signal directly to a receiver hidden someplace, that would invoke the memory-wipe. Primary memory and system backups. We should be able to do that, shouldn’t we?”

Fang-Castro nodded at Martinez, who sighed and said, “Yeah, we can do that. But this stuff really does scare me. The thought of losing all that information… I can’t sleep thinking about it.”

And more to worry about.

Fang-Castro nodded at Barnes. “Major Barnes: your assessment of our overall physical security.”

Barnes picked up a coffee cup and said, “It’s pretty simple, ma’am. If they attack us, we’re screwed. We have no major weaponry. The Nixon has very little maneuvering capability and it is very slow to respond.”

He turned the cup in his hands, as though warming them. “Even if the Celestial Odyssey has no traditional weaponry whatsoever, which I would hardly assume, they can cripple us. All they have to do is maneuver alongside us, turn tail on and rake their exhaust across one of our radiator masts or booms. The nine-thousand-degree plasma’ll take it out in an instant. That’s it for us. We’ve got no propulsion without the radiators. The auxiliary power plant system can provide us with ship-support power forever, but without the big generators online we’ve got insignificant thrust.”

Fang-Castro: “So with hardly any effort on their part, they can leave us adrift in space with no damage to the rest of the Nixon , no immediate loss of life, zip. A perfect surgical strike. There is absolutely nothing we can do to prevent it. If we try to outmaneuver them or counter with our own engines, they are ten times more nimble than we are at our best. If they want to disable us, they will.”

Barnes nodded: “Yes. Then, if we assume they don’t do that, and we take them on board, and they managed to hide some weaponry… well, we have a dozen sidearms and four Taser rifles. The Tasers will disable any EVA suits I’ve ever heard of, and at lower power stages will take down a human. But frankly, that’s not much equipment, if we’re facing a takeover by trained military personnel with more sophisticated equipment.”
