Tsinghua Technology was selected as the leading scientific and technological achievements at the World Internet Conference
At the main venue of the Fifth World Internet Conference held in Wuzhen, Zhejiang Province, 15 global leading scientific and technological achievements were published (in no particular order). CPU hardware security dynamic checking and control (hereinafter referred as DSC) technology of Professor Shaojun Wei's team, who is the director of Microelectronics Institute of Tsinghua University, was selected as a new integrated circuit hardware security technology.
The hardware security of the CPU chip is the security foundation of the computing system. For a long time, everyone used to think that the hardware is safe. But at the beginning of this year, the "Meltdown" and "Spectre" hardware vulnerabilities were exposed, and global mainstream high-performance CPU chips were not immune to these two vulnerabilities. Hundreds of millions of servers, desktops, mobile terminals, etc. were severely affected by security threats, and this is just the tip of the iceberg of CPU hardware security issues. International academic and industrial research on software security has continued for decades, but research on hardware security, especially the hardware security of CPU chips of the core components of information systems, has only just begun in recent years.
Twelve years ago, the team of Shaojun Wei and Leibo Liu of Tsinghua University had noticed this problem when they carried out research work on reconfigurable computing chips. After years of scientific research, the team proposed the DSC technology based on a highly secure and highly flexible reconfigurable computing architecture. This technology is based on the behavior tracking of the CPU, and determines, through rapid analysis and identification, whether there is behavior that damages the hardware safety of the CPU during the operation of the CPU. Whether it is a hardware Trojan, hardware vulnerabilities, hardware backdoors, or malicious use of hardware front doors, it will be quickly discovered by the technical solution due to abnormal CPU chip behavior, and can be controlled according to the hazard level and user safety requirements.
The team of Shaojun Wei, Leibo Liu and China Electronics' Montage Technology used DSC technology for the development of a new X86 architecture CPU. In July 2018, they successfully developed a high performance Jintide® server CPU chip. The Jintide® CPU combines the reconfigurable computing security checking module with the traditional X86 processor core, and can perform real-time checking and control of the behavior of the X86 core during operation. This is the world's first commercial CPU chip that uses a third-party silicon module to dynamically monitor the hardware security of the processor core. Companies such as Lenovo, Great Wall Computer, and H3C have completed the development of high-performance commercial servers based on Jintide® CPU chips, which will be marketed.
Since 2016, the World Internet Conference published yearly 15 leading scientific and technological achievements selected, from nearly a thousand declared projects around the world, by dozens of domestic and foreign authoritative experts. These achievements are generally considered to represent the highest level in the field of Internet and information technology. The achievements selected this year also include: Tencent's WeChat mini-program business model innovation, Huawei's Shengteng 310 chip, Ant Financial's independently controllable financial-grade commercial blockchain platform, Apollo's automatic driving open platform, Tesla's intelligent after-sales service, etc.
