Securing the Internet of Things

February 25, 2019 / technologynetworks

Rice University integrated circuit (IC) designers are at Silicon Valley’s premier chip-design conference to unveil technology that is 10 times more reliable than current methods of producing unclonable digital fingerprints for Internet of Things (IoT) devices.Rice’s Kaiyuan Yang and Dai Li will present their physically unclonable function (PUF) technology today at the 2019 International Solid-State Circuits Conference (ISSCC), a prestigious scientific conference known informally as the “Chip Olympics.” PUF uses a microchip’s physical imperfections to produce unique security keys that can be used to authenticate devices linked to the Internet of Things.Considering that some experts expect Earth to pass the threshold of 1 trillion internet-connected sensors within five years, there is growing pressure to improve the security of IoT devices. Yang and Li’s PUF provides a leap in reliability by generating two unique fingerprints for each PUF. This “...
