“…From these analysis methods, detection and prevention measures have been investigated to tackle deception cyberattacks. On one hand, the detection measures detect corruption of the signals [14]. On the other hand, the prevention measures protect the cyber-physical system by redesigning the control system with the objective of mitigating the control performances degradation [10-13, 15, 18].…”

This article provides control theory methods to analyse, prevent, and assess the feasibility of stealthy ageing attacks on controlled physical systems, modelled as dynamical systems. This new type of attacks leads to premature failures of the physical system by accelerating its ageing and remains stealthy by maintaining the system outputs as in the attack-free case. An attacker with restrained capabilities is considered: it can only corrupt the control signals transmitted to the dynamical system. This article provides set-theoretic methods to analyse and prevent these attacks by restraining the control signals in amplitude, whether the system is stable or not. The proposed methods consist in solving optimisation problems under Linear Matrix Inequality constraints. Then, a method based on linear programming is proposed to assess the feasibility of such attacks by finding the optimal attack control signals. At the end of this article, the methods are applied on two application examples to show their relevances: a thin film manufacturing and a satellite reorientation manoeuvre.

“…In recent years, cyber‐physical systems (CPSs) have experienced significant growth in a wide range of applications including electrical distribution grids, oil and natural gas networks, transportation systems etc. [1, 2]. In the CPSs, there exists a large number of communication links, which makes such systems susceptible to cyber‐attacks targeting the control and sensing modules.…”

In this study, a novel co‐estimation approach is proposed for dynamic state estimation of cyber‐physical systems (CPSs) subjected to sensor attacks. In the proposed approach, the sensory measurements are preprocessed to extract some valuable information about the launched cyber‐attack. This information is then manipulated to form new state equations, which are augmented with the CPS model. The newly obtained model effectively represents the behaviour of both the CPS states as well as the launched cyber‐attack, and can be used for their co‐estimation. Two structures are suggested for the preprocessing of the sensory measurements that deploy Kalman filter (KF) and two‐step KF for co‐estimation of the states and cyber‐attacks. To effectively handle the concurrent effects of cyber‐attacks and unknown inputs on the CPS co‐estimation process, some auxiliary outputs are generated using high‐gain approximate differentiators to realise the required matching conditions. The proposed dynamic co‐estimation approach improves accuracy via considering the inter‐correlation between the CPS states and the cyber‐attacks. To demonstrate the viability of the proposed co‐estimation method, thorough stability and feasibility analysis are provided. Furthermore, extensive simulations are performed on a well‐known CPS‐the IEEE 14‐bus test system‐ to demonstrate the effectiveness of the proposed approach.
