PROJECT TITLE :

Cross-Layer Codesign for Secure Cyber-Physical Systems

ABSTRACT:

Security attacks could have disruptive consequences on cyber-physical systems, and cause significant social and economic losses. Building secure cyber-physical systems is significantly difficult due to the variety of attack surfaces from the cyber and physical elements, and usually to limited computation and communication resources. In this paper, we have a tendency to propose a cross-layer design framework for resource-constrained cyber-physical systems. The framework combines management-theoretic methods at the useful layer and cybersecurity techniques at the embedded platform layer, and addresses security together with alternative design metrics such as control performance underneath resource and real-time constraints. We have a tendency to use the concept of interface variables to capture the interactions between control and platform layers, and quantitatively model the relation among system security, performance, and schedulability via interface variables. The general codesign framework is customized and refined to the automotive domain, and its effectiveness is demonstrated through an industrial case study and a set of synthetic examples.
