This interview with Warren Savage, guest researcher t the University of Maryland in IoT security is a follow up to an interview I did with him last year at the @DesignCon conference in Santa Clara. In the interview and his keynote at the show, he talked about how vulnerable the electronics supply chain was. A year later we are stuck in a semiconductor supply chain slowdown and one of the reasons is the inability to secure it. Things haven't gotten much better but Savage sees progress. This is part two of a series on supply chain.
