Self-Destructing Circuits and More Security Schemes

Cars That Think

Last week at the International Solid-State Circuits Conference (ISSCC), researchers introduced several technologies to fight even the sneakiest hack attacks. If it picks up that signal it engages what Lao called a protection engine, logic that can guard against the attack by, for example, instructing the processor to encrypt its data traffic.
