AISS does for chip and supply chain security what fluoride did for a dental health. Security is integrated into the design flow” from the start, Leef said.
Chip tracking technologies like infinite tracing” have emerged in recent months as the U.S. seeks to block Chinese access to advanced chip-making equipment. The AISS program uses an emerging security framework called PUF, physical unclonable feature. The device-level approach exploits inherent randomness introduced during manufacturing to give each chip a unique identifier.
Secured chips could then be tracked from conception, design and deployment and throughout their lifecycles via passive or active tags, the latter including built-in memory for storing cryptographic keys. The DARPA framework would assign a unique ID for each AISS-design chip, akin to a unique human fingerprint.
The agency’s approach represents a fundamental shift in chip design. Until now, security tended to be a higher layer software problem,” said Daniel Cooley, chief strategy officer at Silicon Labs. But it’s now working its way down deep into the technology stack to the foundries. Actually, things are happening at the foundries, chip design houses, and [at] every level of the technology stack.”
AISS is part of that secure hardware push. While focused on Arm-based architectures, other secure design efforts are focuses on RISC-V and other emerging architectures, industry sources said.
The three-phase DARPA program will move from a generic SoC design incorporating the AISS security engine to what is hoped will be a marrying of system synthesis and baked-in chip security that would allow for tracking devices throughout their lifecycle.
A team led by EDA vendor Synopsys will focus on both system synthesis and design security. The team includes Arm and U.K.-based embedded analytics vendor UltraSoC, each of which will contributed semiconductor IP to the effort.
UltraSoC’s framework is embedded in chips to perform analytics on chip operations, sounding an alarm when it detects suspicious behavior. The approach complements security techniques like Arm’s TrustZone. That is a lock, we are the burglar alarm,” said UltraSoC CEO Rupert Baines,
The results of the three-phase AISS program will be released incrementally,” Leef said, so chip designers could eventually embed security into complete device designs up to several hundreds of thousands of gates.
McKinsey expects consumer preferences will shift to less expensive phones, which will also negatively affect demand for semiconductors. Apple, in fact, on April 15 released its latest iPhone SE at a price point of $399 — its least expensive smart phone in four years.
The recovery of mobile-phone sales will vary by geography, with China likely to see an uptick before Europe and the United States, since its economy is closer to recovery.
For wireless communication infrastructure — 5G in particular — McKinsey expects two different demand patterns. In areas that have not launched 5G networks, telecom providers will likely postpone investments and instead focus on improving their existing networks to accommodate rising data traffic. By contrast, some telecom providers in areas that already have 5G will double down on their investments, especially if governments provide subsidies in an attempt to stimulate the local GDP.
Wired communicationDemand for semiconductors used in wired communication applications will increase by 8% to 11% in 2020 because of several pandemic-related factors, including:
