英伟达首席安全官David Reber在官网发文，确认英伟达GPU不存在也不应该设置终止开关和后门。“英伟达设计处理器已有30多年。在芯片中嵌入后门和终止开关无异于给黑客和敌对分子送去大礼。这将破坏全球数字基础设施，并破坏人们对美国技术的信任。现行法律明智地要求企业修复漏洞，而不是制造漏洞。”David Reber引用上世纪90年代克林顿政府时期的Clipper Chip项目（曲别针芯片，通过要求在产品中加入一个小型芯片硬件，在加密系统里形成漏洞，从而保证政府能够解密）的失败案例，并强调硬件的完整性应无党派之分且不容商榷。外汇交易员 (@myfxtrader):国家网信办：近日，英伟达算力芯片被曝出存在严重安全问题。网信办于2025年7月31日约谈了英伟达公司，要求英伟达公司就对华销售的H20算力芯片漏洞后门安全风险问题进行说明并提交相关证明材料。 https://t.co/XKzr6W1Soh ...
