Beijing: Nvidia denied on Tuesday a Chinese accusation that the US chip maker's AI chips have mature tracking and location and remote shutdown technologies. The company asserted that its chips have no "backdoors or kill switches."

According to Anadolu Agency, Nvidia's Chief Security Officer David Reber emphasized in a blog post that "NVIDIA GPUs do not and should not have kill switches and backdoors." Reber argued that embedding such features would be a boon for hackers and hostile entities, undermining global digital infrastructure and eroding trust in U.S. technology. He highlighted that established laws sensibly mandate companies to rectify vulnerabilities rather than create them.

Reber contended that secret backdoors contravene fundamental cybersecurity principles and present significant vulnerabilities that could be exploited by hackers. He further stated that incorporating a kill switch or backdoor into products like Nvidia GPUs would be detrimental to US national security interests.

The response from Nvidia came after the Cyberspace Administration of China (CAC) summoned the company last week to address the "backdoor security risks" alleged in its H20 computing chips. The CAC claimed that US AI experts discovered mature tracking and location and remote shutdown technologies in Nvidia's chips.

In April, Washington restricted Nvidia from selling its H20 chips to China, citing an escalation in the tech conflict with Beijing. The US indicated that an export license would be necessary "for the indefinite future" to sell these chips to China. As a result, Nvidia announced it anticipated writing down charges of up to $5.5 billion in its fiscal first quarter due to these US export requirements.

Last month, Nvidia declared its intention to resume H20 AI chip sales to China following the US's commitment to lifting licensing restrictions.
