Hardware Security Set To Grow Quickly
By Adam Kovac - 22 Aug, 2024 - Comments: 0

Experts At The Table: The hardware security ecosystem is young and relatively small but could see a major boom in the coming years. As companies begin to acknowledge how vulnerable their hardware is, industry standards are being set, but must leave room for engineers to experiment. As part of an effort to determine the best way forward, Semiconductor Engineering sat down with a panel of experts... » read more

Chip Security Now Depends On Widening Supply Chain
By Ann Mutschler - 01 Aug, 2024 - Comments: 0

Securing chips is becoming more challenging as SoCs are disaggregated into chiplets, creating new vulnerabilities that involve hardware and software, as well as multiple entities, and extending threats across a much broader supply chain. In the past, much of the cyber threat model was confined to either hardware or software, and where multiple vendors were involved, various chips were separa... » read more
