Nvidia faces security probe in China

Beijing is demanding answers from Nvidia just weeks after Washington lifted the export ban on its AI chips. China's cyberspace regulator has summoned the U.S. company, raising concerns that its H20 chips contain backdoors. What exactly is a hardware backdoor? Are China's worries about chip security justified? How difficult is it to prove a chip is truly secure? And if backdoor functions are validated, what could this mean for Nvidia's business in the world's second-largest market?

Host Tu Yun joins Prof. Toby Walsh, the Chief Scientist of the AI Institute, University of New South Wales, Australia, Andy Mok, a senior research fellow at the Center for China and Globalization, and Professor Qu Qiang, a fellow of the Belt and Road Research Center, Minzu University of China to take a close look.
