Nvidia’s chief security officer has published a blog post insisting that its GPUs “do not and should not have kill switches and backdoors.” It comes amid pressure from both sides of the Pacific, with some US lawmakers pushing Nvidia to grant the government backdoors to AI chips, while Chinese officials have alleged that they already exist.

The US is looking at requiring 'software or physical changes' to enable chip-based location tracking to stop Nvidia’s most advanced AI chips from being smuggled into China.

Embedding weaknesses into chips would ‘undermine global digital infrastructure and fracture trust in US technology’, Nvidia says.
