BEIJING, Aug 6 (Reuters) - Nvidia ( NVDA ) has published

a blog post reiterating that its chips did not have backdoors or

kill switches and appealed to U.S. policymakers to forgo such

ideas saying it would be a "gift" to hackers and hostile

actors.

The blog post, which was published on Tuesday in both English

and Chinese, comes a week after the Chinese government summoned

the U.S. artificial intelligence (AI) chip giant to a meeting

saying it was concerned by a U.S. proposal for advanced chips

sold abroad to be equipped with tracking and positioning

functions.

The White House and both houses of U.S. Congress have proposed

the idea of requiring U.S. chip firms to include location

verification technology with their chips to prevent them from

being diverted to countries where U.S. export laws ban sales.

The separate bills and White House recommendation have not

become a formal rule, and no technical requirements have been

established.

"Embedding backdoors and kill switches into chips would be a

gift to hackers and hostile actors. It would undermine global

digital infrastructure and fracture trust in U.S. technology,"

Nvidia ( NVDA ) said. It had said last week its products have no

backdoors that would allow remote access or control.

A backdoor refers to a hidden method of bypassing normal

authentication or security controls.

Nvidia ( NVDA ) emphasized that "there is no such thing as a 'good'

secret backdoor - only dangerous vulnerabilities that need to be

eliminated."
