Infinite Horizon Privacy in Networked Control Systems: Utility/Privacy Tradeoffs and Design Tools. (arXiv:2303.17519v1 [cs.CR])

We address the problem of synthesizing distorting mechanisms that maximize
infinite horizon privacy for Networked Control Systems (NCSs). We consider
stochastic LTI systems where information about the system state is obtained
through noisy sensor measurements and transmitted to a (possibly adversarial)
remote station via unsecured/public communication networks to compute control
actions (a remote LQR controller). Because the network/station is
untrustworthy, adversaries might access sensor and control data and estimate
the system state. To mitigate this risk, we pass sensor and …
