Nvidia测试软件,以核实AI芯片位置,旨在阻止向中国的出口。 Nvidia tests software to verify AI chip locations, aiming to block exports to China.

Nvidia正在为其AI芯片开发一个基于软件的地点核查系统,利用服务器通信中的时间间隔分析来估计芯片的地理位置,以防止未经授权的出口,特别是出口到中国。 Nvidia is developing a software-based location verification system for its AI chips, using time-delay analysis in server communications to estimate a chip’s geographic location, aiming to prevent unauthorized exports, particularly to China. 该功能是利用Blackwell GPUs的保密计算,是选择性的,仍在私人测试中,今后有可能扩大到老的Hopper和Ampere芯片。 The feature, leveraging confidential computing in Blackwell GPUs, is optional and still in private testing, with potential future expansion to older Hopper and Ampere chips. 它回应了美国政府的压力和最近涉及非法芯片运输的刑事案件,而Nvidia否认了中国网络安全监管机构在审查中提出的后门指控。 It responds to U.S. government pressure and recent criminal cases involving illicit chip shipments, while Nvidia denies claims of backdoors amid scrutiny from China’s cybersecurity regulator.
