China Accuses Nvidia of H20 Chip Backdoor for Chinese Market
▼ Summary
– Beijing summoned Nvidia over alleged security issues with its AI chips, impacting the company’s efforts to revive sales in China.
– China’s cyber regulator claimed Nvidia’s chips have location tracking and remote shutdown capabilities, citing US experts.
– Nvidia was asked to explain security concerns related to its H20 chip, designed for China under US export restrictions.
– Nvidia’s CEO visited Beijing to reaffirm commitment to the Chinese market and introduced a new chip compliant with US controls.
– A China tech expert expressed skepticism about claims of a deliberate back door in Nvidia hardware, citing lack of detailed evidence.
China has raised concerns about potential security vulnerabilities in Nvidia’s H20 AI chips, escalating tensions between the US tech giant and Beijing. The Cyberspace Administration of China recently held discussions with Nvidia officials, demanding explanations for what it described as serious security risks linked to the company’s hardware.
According to Chinese authorities, independent US researchers allegedly discovered that Nvidia’s AI chips contain location-tracking capabilities and could be remotely deactivated. The regulator specifically questioned the H20 model, a modified version developed to meet US export restrictions while catering to the Chinese market. Nvidia has been instructed to provide detailed documentation addressing these security claims.
This development follows Washington’s recent decision to allow H20 chip sales to China after initially blocking them. Nvidia CEO Jensen Huang visited Beijing shortly after the policy shift, reaffirming the company’s dedication to Chinese clients. During the trip, he also unveiled a new graphics processing unit from the Blackwell series, engineered to comply with current US trade regulations.
Industry analysts remain doubtful about the validity of China’s allegations. Paul Triolo, a technology policy specialist, expressed skepticism, noting the lack of concrete evidence supporting claims of intentional backdoor access in Nvidia’s hardware. The situation highlights the growing scrutiny of foreign technology in China, even as companies like Nvidia attempt to navigate complex geopolitical and trade challenges.
