A Bayesian Nash equilibrium-based moving target defense against stealthy sensor attacks
David Umsonst, Serkan Sarıtaş, György Dán +1
We present a moving target defense strategy to reduce the impact of stealthy sensor attacks on feedback systems. The defender periodically and randomly switches between thresholds…
Privacy Guarantees for Cloud-based State Estimation using Partially Homomorphic Encryption
Sawsan Emad, Amr Alanwar, Yousra Alkabani +3
The privacy aspect of state estimation algorithms has been drawing high research attention due to the necessity for a trustworthy private environment in cyber-physical systems. The…
Experimental evaluation of sensor attacks and defense mechanisms in feedback systems
David Umsonst, Henrik Sandberg
In this work, we evaluate theoretical results on the feasibility of, the worst-case impact of, and defense mechanisms against a stealthy sensor attack in an experimental setup. We…
Multi-Layer SIS Model with an Infrastructure Network
Philip E. Pare, Axel Janson, Sebin Gracy +3
This paper deals with the spread of diseases over both a population network and an infrastructure network. We develop a layered networked spread model for a susceptible-infected-su…
A Model Randomization Approach to Statistical Parameter Privacy
Ehsan Nekouei, Henrik Sandberg, Mikael Skoglund +1
In this paper, we study a privacy filter design problem for a sequence of sensor measurements whose joint probability density function (p.d.f.) depends on a private parameter. To e…
Geometrical Characterization of Sensor Placement for Cone-Invariant and Multi-Agent Systems against Undetectable Zero-Dynamics Attacks
Jianqi Chen, Jieqiang Wei, Wei Chen +3
Undetectable attacks are an important class of malicious attacks threatening the security of cyber-physical systems, which can modify a system's state but leave the system output m…
