Nvidia said in a blog post published in English and Chinese on 5–6 Aug. that its graphics-processing units "do not and should not have kill switches and backdoors." The post, titled "No Backdoors. No Kill Switches. No Spyware.," reiterates that no remote-disable or hidden access functions are built into its chips. The company’s statement follows a summons from China’s Cyberspace Administration, which questioned whether Nvidia’s H20 AI processors contained secret controls, and coincides with draft U.S. legislation that would require advanced chips to carry location-tracking technology and potentially a hardware kill switch to enforce export rules. Chief security officer David Reber Jr. warned that embedding such features would be “a gift to hackers and hostile actors” and would undermine trust in U.S. technology. Nvidia urged American policymakers to abandon the idea, saying robust security comes from eliminating, not creating, single-point vulnerabilities.
