An innovative security architecture for low cost low power IoT devices based on secure elements: A four quarters security architecture

摘要

This demonstration presents a low cost, low power object based on Arduino board, whose security is enforced by a secure element. Most of IoT devices are built over a General Purpose Unit (GPU) associated to a radio System on Chip (SoC), and controlling multiple sensors and/or actuators. We designed a similar architecture, in which communications are secured by a TLS server running in a secure element. This secure chip performs strong mutual authentication with remote clients dealing with X509 certificates, and acts as an identity module.
