Security Challenges in CPS and IoT: From End-Node to the System

The rising of cyber-physical systems (CPS) and Internet of Things (IoT) has significantly increase the industrial productivities and customer convenience. However, the widely distributed CPS and IoT systems also breeds new challenges among which security is a major concern. In order to help build secure and resilient CPS/IoT systems, systematic analyses are performed on CPS and IoT from individual smart devices which serve as the end nodes to the entire system. The analysis results will help identify the vulnerabilities of CPS/IoT systems and/or provide guidance on how to build security into these systems. Security mitigation methods will also be discussed which can help balance security with other criteria such as safety and performance.
