The Discovery Park Big Idea Challenge : Towards Cyber-Physical Vetting of Critical Infrastructures

[2019- ongoing]

Critical infrastructures, such as those in civil, energy, manufacturing, and defense domains, are increasingly interwoven with cyber components such as sensing, computing, and control devices. A grand challenge arising from such Cyber-Physical Infrastructures (CPIs) is to protect them from cyber and/or physical attacks, which have posed real, significant threats to organizational and national security. The project is focused on the vulnerability analysis of CPIs and algorithm design for achieving higher security level.

In this project, we model the CPS subject to cyber-attacks as a hybrid system so that it can account for both the switching attack that tampers the discrete state dynamics (logical behavior) and the data injection attack which compromises the continuous state dynamics (physical behavior) of the CPS. Specifically, the identifiability and severity of the joint attacks are first analyzed, and a unified resilient hybrid control scheme is proposed to mitigate the impact of faults/attacks.
