The Chinese Embassy in Panama on Saturday rejected remarks by US officials that sought to smear Chinese technology companies, criticizing Washington for making baseless allegations and engaging in technological bullying, according to a statement released by the embassy on Monday.
The embassy said it had noted that the US Embassy in Panama had reposted on social media remarks by certain US officials making unfounded accusations against Chinese technology companies.
"Fabricating facts and distorting right and wrong are habitual tactics of some US politicians," the Chinese embassy said, stressing that US claims that Chinese companies conduct espionage activities for the Communist Party of China lack basic factual grounds.
Whether a company's products are secure should be determined by facts and technology, rather than political accusations, the embassy said.
It noted that Chinese companies operate on a market basis in Panama and other Latin American countries, strictly comply with local laws and industry standards, and have won recognition from users while making positive contributions to local economic and social development and employment.
The embassy also accused the US of "crying thief while stealing" and "shifting the blame," saying Washington has generalized the concept of national security, restricted the normal development of Chinese companies and pressured regional countries to replace Chinese products.
"This is blatant technological bullying," the embassy said.
The US, which is truly keen on conducting espionage activities around the world and does not even spare its allies, should not accuse others of the same, the embassy said.
"For those whose minds are filled only with geopolitical calculations, they might even suspect that there is a listening device in a shaomai dumpling," the embassy said, using a sarcastic remark to mock what it described as Washington's excessive suspicion of Chinese technology.

。Caliptra 旨在完全集成到 SoC / ASIC 中，以提供与当今单独的信任根解决方案相媲美的集成安全性，同时它围绕现代边缘 / 机密计算场景的需求而设计。有趣的是，Caliptra 的参考实现，使用了 RISC-V 内核。奇怪的是，虽然红（AMD）蓝（NVIDIA）都已官宣支持 Caliptra，但蓝厂（Intel）却在今日的公告中意外缺席。至于具有 Caliptra 硅信任根的目标，新规范中是这么描述的：在本质上，Caliptra Silicon RoT 的范围是刻意做到极简的，以推动规范定义的敏捷性、最大限度地提高适用性，并且推动行业对齐、一致性和更快地采用基础设备安全原语。

B | 一个定义明确的规范，可在最大限度上提升架构的可组合性，跨 CSP、产品和供应商的可重用性，以及开源的可行性。虽然增强功能、高级用例和应用程序超出了本规范的范围，但各方仍可通过硅 RoT 和社区参与的途径，加入到这一开发路线图中。Caliptra 定义了硅内部 RoT 基线的设计标准，满足测量信任根（RTM）角色。

C | 并且 Caliptra 的开源实现，推动了 RTM 和锚定硬件证明的测量机制的透明度。

D | 需要注意的是，Caliptra Silicon RoT 必须启动 SoC、测量其加载的可变代码，以及控制 SoC 中非易失性配置位的突变。

E | 最后，Caliptra Silicon RoT 使用基于独特的“每资产加密熵”的签名证明来报告这些测量结果，因而能够作为 SoC 身份的信任根。感兴趣的朋友，可移步至 OpenCompute.org 官网了解完全开放的 Caliptra 规范。至于更多技术细节，还请留意本周的 OCP（开放计算项目）活动。
