Securing Real-Time Internet-of-Things
It addresses security issues for critical cyber-physical systems with real-time requirements, such as avionics and power grids, but is incremental as it focuses on outlining existing approaches and challenges rather than proposing new solutions.
The paper introduces real-time Internet-of-Things (RT-IoT) systems, highlighting their benefits and the increased cyber-attack risks due to connectivity, and provides an overview of current approaches and research challenges for securing them.
Modern 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.). Recent developments and new functionality requires real-time embedded devices to be connected 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 efficient use of next-generation embedded devices. However RT- IoT are also increasingly becoming targets for cyber-attacks which is exacerbated by this increased connectivity. This paper gives an introduction to RT-IoT systems, an outlook of current approaches and possible research challenges towards secure RT- IoT frameworks.
