False data injection attacks on networked control systems.

The integration of cyber (network) with physical world is a big step in cyber-physical systems. This has revolutionised many industries. But this transformation has made cyber-physical systems vulnerable to attacks. One particular type of attack is the adversarial false data injection which injects false data in either the sensor measurements or the corresponding communication channel. A better understanding of how false data injection (FDI) attacks are constructed is crucial for developing strategies to protect against such attacks. In this paper, we consider two models for networked control systems and present an algorithm for constructing FDI attacks in each case and compare with an existing approach. The conditions for the attack to remain stealthy for systems equipped with a $ \chi ^2 $ χ 2 failure detector and the design of attack vectors that satisfy these conditions are discussed in detail. The algorithms are demonstrated by developing FDI attacks for two real-world examples. [ABSTRACT FROM AUTHOR]
