Zhou Hongyi on Nvidia Chips and “Backdoors”: Technical Detection Difficult, Intent Matters

Zhou Hongyi, founder of 360, addressed concerns about Nvidia’s H20 AI chip security at a Beijing conference, following reports of Chinese regulatory scrutiny. While acknowledging the difficulty of detecting hardware backdoors, Zhou stated software-related vulnerabilities are inevitable. He distinguished between intentional backdoors and unintentional vulnerabilities, suggesting China’s suspicions are reasonable given past US government requests to Nvidia. Despite this, Zhou believes Nvidia likely has no deliberate malicious intent and proposed a third-party security audit to address concerns. Nvidia denies any backdoors in its chips.

CNBC AI News, August 7th – At the recent 13th Internet Security Conference in Beijing, Zhou Hongyi, founder of 360, addressed concerns regarding potential security risks associated with Nvidia’s H20 AI chips in an interview with Phoenix Television.

The discussion stemmed from reports that Nvidia was recently summoned by Chinese regulators to address these potential vulnerabilities.

Zhou stated that technically, it’s exceptionally difficult to definitively determine the existence of a “backdoor” in Nvidia’s H20 silicon.

He elaborated by explaining that hardware requires drivers to function, and these drivers, being software, inherently introduce the possibility of vulnerabilities. “Software-defined systems inevitably have vulnerabilities.”

The key distinction, according to Zhou, lies in intent. “A vulnerability intentionally introduced is a backdoor, while an unintentionally introduced vulnerability is simply a vulnerability. Given the U.S. government’s past requirements of Nvidia, China’s suspicions are understandable.”

Zhou acknowledged Nvidia’s significant market share in China, suggesting that the company likely has no deliberate intention of embedding malicious code or establishing backdoors within its software.

To alleviate concerns, Zhou proposed that Nvidia engage a third-party cybersecurity firm to conduct a comprehensive security audit of its H20 chips.

On July 31st, China’s State Internet Information Office reportedly met with Nvidia, demanding an explanation and supporting documentation regarding potential security risks, specifically backdoors and vulnerabilities, in the company’s H20 AI chips destined for the Chinese market.

Nvidia responded on August 1st, stating: “Cybersecurity is of paramount importance to us. NVIDIA chips do not have ‘backdoors’ and do not allow anyone to remotely access or control these chips.”

On August 6th, Nvidia reiterated its stance in an official statement, asserting “Nvidia chips have no backdoors, kill switches, or monitoring software.”
