In recent years, networked control systems (NCSs) have received ever-increasing interest from researchers owing to the advantages of improving flexibility and efficiency of systems and decreasing maintenance costs. However, the growing openness of NCSs, highly depending on network communication technology, induces many unforeseen vulnerabilities in the control systems and leads to increasing security risks as highlighted in [1]. Adversaries can easily exploit these vulnerabilities to launch attacks to degrade performance of systems, and even destroy the stability of systems in the worst case. Hence, secure control of networked control systems have been a subject of significant research interest for the last two decades (e.g., [2, 3]). Denial-of-service (DoS) attack is perhaps one of the most detrimental attacks that affect the packet delivery. By blocking the communication link and effectively preventing transmission of packets between the plant and the controller, DoS attacks could destroy the availability of signals among different nodes of the NCSs, and furthermore, drive the systems to be unstable.
