Design and Implementation of Attack-Resilient Cyber-Physical Systems

In recent years, we have witnessed a significant increase in the number of security related incidents in control systems. These include high-profile attacks in a wide range of application domains – from attacks on critical infrastructure, as in the case of the Maroochy Water breach [1], and industrial systems (e.g., the StuxNet virus attack on an industrial SCADA system [2], [3]), to attacks on modern vehicles [4], [5], [6]. Even high-assurance military systems were shown to be vulnerable to attacks, as illustrated in the highly publicized downing of the RQ170 Sentinel US drone [7], [8], [9]. These incidents have seriously raised security awareness in Cyber-Physical Systems (CPS), which feature tight coupling of computation and communication substrates with sensing and actuation components. However, the complexity and heterogeneity of this next generation of safety-critical, networked and embedded control systems have challenged the existing design methods in which security is usually consider as an afterthought.
