Nvidia Rejects US Demand For Backdoors in AI Chips

(Wednesday August 06, 2025 @05:21PM (msmash) from the between-rock-and-hard-place dept.)


Nvidia's chief security officer has published [1]a blog post insisting that its GPUs " [2]do not and should not have kill switches and backdoors ." From a report:

> It comes amid pressure from both sides of the Pacific, with some US lawmakers pushing Nvidia to grant the government backdoors to AI chips, while Chinese officials have [3]alleged that they already exist .

>

> David Reber Jr.'s post seems pointedly directed at US lawmakers. In May a bipartisan group introduced the Chip Security Act, a bill that would require Nvidia and other manufacturers to include tracking technology to identify when chips are illegally transported internationally, and leaves the door open for further security measures including remote kill switches. While Nvidia is expecting to be granted permits to once again sell certain AI chips in China, its most powerful hardware is still under strict US export controls there and elsewhere.

On the surface, this reads like you want to give up on democracy, because essentially that's what democracy is: a popularity contest. The only way you get elected officials in a democracy to be elected via merit and expertise is with an educated population that isn't easily swayed by emotional appeals, and watch how quickly some dimwit lashes out at me for saying it.

by Nkwe ( 604125 )

So how would a backdoor in a chip actually work (specifically and technically)? In the case of a CPU or GPU are we talking about a special instruction that when executed kills the chip (blows a fuse or something), are we talking about an extra hardware pin that when the signal is raised or lowered kills the chip, or what? I ask because the concept of a backdoor in hardware seems kind of weird. It seems that it would also need a significant software or firmware component, as well as off chip hardware in order to trigger the kill. If software, firmware, or off chip hardware is required, what would prevent someone from just not implementing that hardware or not installing that software in order to close the backdoor? Or are we really talking about a backdoor implemented in a reference design, chip set, or other tech that isn't really just the CPU/GPU? If it's a reference design, what prevents the adversarial country or party from not using the reference design?

I get that there are things like the management engine in Intel reference designs, and when using the reference design the built in network interface has an extra endpoint not seen by the operating system, but one could protect themselves by either firewalling the machine or adding their own network interface (and not plugging in the built in one). GPUs typically don't have built in network interfaces, so how would a GPU "backdoor" be remotely accessed or triggered?

I am not saying that it can't happen, but I would love to know the technical details on how it could.
