数据保密在现代网络通讯或电子商务中至关重要。保密(安全)微处理器的诞生,就是为了抵御各种对安全机制的入侵和加速保密运算操作。该文着重于分析当代保密(安全)微处理器的新技术以及在这类微处理器设计中所面临的挑战,并讨论这些技术的强弱点。 Data privacy is crucial in modern web communications or e-commerce. Confidential (secure) microprocessor was born, is to resist all kinds of invasion of security mechanisms and accelerate the confidential computing operations. The paper focuses on new technologies for analyzing contemporary confidential (secure) microprocessors and the challenges they face in designing such microprocessors, as well as discussing the strengths and weaknesses of these technologies.
