Nvidia emphasizes that its GPUs must remain free of kill switches and backdoors in a blog post by its chief security officer amidst pressure from US lawmakers and Chinese officials. The Chip Security Act proposes tracking technology and potential kill switches for AI chips. Concerns about secret backdoors exist, linked to investigations into vulnerabilities in purchased chips in China. Reber Jr. argues that backdoors are dangerous vulnerabilities. He warns that such policies would harm national security and economic interests while aiming to maintain Nvidia's dominance in the AI chip market in China.
To mitigate the risk of misuse, some pundits and policymakers propose requiring hardware 'kill switches' or built-in controls that can remotely disable GPUs without user knowledge and consent. Some suspect they might already exist, in a nod to a probe already launched in China over alleged 'loopholes and backdoor' vulnerabilities in the H20 chips that have been sold in the country.
There is no such thing as a 'good' secret backdoor, only dangerous vulnerabilities that need to be eliminated. Kill switches are an open invitation for disaster.
That's not sound policy. It's an overreaction that would irreparably harm America's economic and national security interests.
