Securing Real-Time Internet-of-Things

Today's embedded and cyber-physical systems are ubiquitous. A large number of critical cyber-physical systems have real-time requirements (e.g., avionics, automobiles, power grids, manufacturing systems, industrial control systems, etc.). The current trend is to connect real-time embedded devices to the Internet. This gives rise to the real-time Internet-of-things (RT-IoT) that promises a better user experience through stronger connectivity and better use of next-generation embedded devices, albeit with safety-critical properties. However RT-IoT are also increasingly becoming targets for cyber-attacks as evident by recent events. This paper gives an introduction to RT-IoT systems, an outlook of current approaches and possible research challenges towards a holistic secure RT-IoT framework.
