The Internet of Things makes our lives more streamlined and convenient, but the cybersecurity risk posed by millions of wirelessly connected devices remains a huge concern. UC Santa Barbara is putting an extra layer of security on the growing number of internet- and Bluetooth-enabled devices with technology that aims to prevent cloning.

Key to this technology is the memristor, or memory resistor, that can change its output in response to its histories. A circuit made of memristors results in a black box of sorts, with outputs extremely difficultto predict based on the inputs.
