Resilience to denial-of-service and integrity attacks: A structured systems approach

The resilience of cyberphysical systems to denial-of-service (DoS) and integrity attacks is studied in this paper. system modeled as a linear structured system, its an attack interpreted graph theoretical framework. structural the characterized terms unmatched vertices maximum matchings bipartite connected components directed representations under attack. We first present conditions for be resilient DoS when adversary may block access or turn off certain inputs system. extend analysis characterize might additionally have ability affect implementation state-feedback control strategies. This termed establish which that structurally will also class attacks. Finally, we formulate extension case switched systems, derive such
