Detection and Defense of industrial cyber-physical systems through side-channel leakage

Industrial Cyber-Physical Systems (ICPS) are intricately networked and highly integrated systems.
Due to these connections, these systems are more susceptible to attacks that could result in collateral damage.
The goal of this research is to improve the security of Industrial Cyber-Physical Systems (ICPS) by utilizing side-channel leakage.
On the one hand, side-channel leakage is used to detect anomalies in real-time while accruing low computation and infrastructure costs. The current state of the art in sound-based anomaly detection methods is reviewed, while limitations and issues are highlighted. To overcome these limitations, a real-time sound-based anomaly detection approach is being developed.
On the other hand, the study also focuses on improving the security of lightweight cryptography algorithms,
which are commonly used in ICS systems with limited resources. A theoretical attack on the Linear Feedback Shift Registers (LFSR) of the Elephant algorithm is proposed and two countermeasures are suggested to counter this attack.
