DARPA unveils first SSITH prototype to mitigate hardware flaws

DARPA is still in the early prototype stages of its SSITH program, but the aim is to develop an open source chip able to block hardware attacks and reduce the need for software patches.

searchsecurity.techtarget.com, Aug. 23, 2019 – 

DARPA aims to block hardware attacks at the source and reduce the need for software patches and has turned to a new microprocessor design to help achieve that goal.

DARPA first announced the project, dubbed SSITH, in 2017 and Dr. Linton Salmon, program manager in the microsystems technology office at DARPA, presented the project and the first prototype chip at this year's DEF CON event in Las Vegas. He admitted he had to force the naming of the project -- System Security Integration Through Hardware and Firmware -- to fit the SSITH acronym.

According to Salmon, DARPA has six teams working on 15 different SSITH prototypes using open source RISC-V cores and ranging from low-end IoT devices up to high-end systems.

"The goal of the program is to provide security against hardware vulnerabilities that are exploited through software [and] to increase security throughout the microelectronics enterprise, whether you're talking about small IoT devices or you're talking about a high-performance computing system that costs hundreds of millions of dollars," Salmon said.
