Scientists find security risk in RISC-V open-source chip architecture that China hopes can help sidestep US sanctions


US lawmakers reportedly consider sanctions to restrict RISC-V access because of concerns of rapid technology transfer and Chinese adoption of architecture.

It was first reported by the National Computer Network Emergency Response Technical Team/Coordination Centre of China (CNCERT) on April 24, and NPU gave further details in an official announcement on May 24. Silicon Valley chip specialist Jim Keller, a microprocessor engineer who has worked for AMD, Apple and Intel, highlighted the limitless potential of RISC-V during a speech in March, noting its prospective role in powering unprecedented AI software applications. Initiated in 2021, the programme focused on the research and detection of hardware vulnerabilities and was carried out by CNCERT, Tsinghua University, NPU and the Institute of Microelectronics of the Chinese Academy of Sciences.
