Nvidia blasts proposals for chip backdoors as US considers “kill switch”

In a strong response to allegations from the Chinese government, Nvidia has firmly denied the existence of backdoors or kill switches in its chips. The company's Chief Security Officer, David Reber Jr., emphasized through a recent blog post that, "There are no back doors in NVIDIA chips. No kill switches. No spyware. That's not how trustworthy systems are built—and never will be." The controversy emerged after the Cyberspace Administration of China stated that Nvidia's technology posed serious security concerns. They claimed that US AI experts had disclosed that Nvidia’s computing chips were capable of location tracking and could potentially disable technology remotely. This accusation specifically targets Nvidia's H20 chip designed for the Chinese market, which was developed in response to US export regulations. Meanwhile, US lawmakers are advancing a Chip Security Act that would mandate the incorporation of "location verification" in exported chips. This legislation also seeks to evaluate mechanisms that could prevent unauthorized usage, a move critics argue could create a system akin to the "kill switch" that Nvidia is actively opposing. According to Senator Tom Cotton's office, the initiative aims to safeguard advanced American chips from being accessed by adversaries such as Communist China by enhancing oversight of these technologies. In parallel, the White House's AI Action Plan urges government agencies and chip manufacturers to consider utilizing both new and existing location verification technologies to ensure that chips are not exported to nations deemed concerning. In light of these developments, Nvidia reiterated its stance last week, stating to various media outlets that there are no hidden "backdoors" in their chips that would allow unauthorized remote access or control. Reber Jr.'s blog post further elaborated on the dangers of implementing backdoors, suggesting that such demands should be rejected. He pointed out that some policymakers have proposed the introduction of hardware "kill switches" that could disable GPUs without user consent, a notion he argues is both risky and unwarranted. "Nvidia GPUs do not and should not have kill switches and backdoors," he asserted, highlighting the importance of maintaining trust in technology.
