Controller confidentiality under sensor attacks refers to whether theinternal states of the controller can be estimated when the adversary knows themodel of the plant and controller, while only having access to sensors, but notthe actuators. We show that the controller's state can be estimated accuratelywhen the nonlinear closed-loop system is detectable. In the absence ofdetectability, controller confidentiality can still be breached with a periodicprobing scheme via the sensors under a robust observability assumption, whichallows for the controller's state to be estimated with arbitrary accuracyduring the probing period, and with bounded error during the non-probingperiod. Further, stealth can be maintained by choosing an appropriate probingduration. This study shows that the controller confidentiality for nonlinearsystems can be breached by balancing the estimation precision and thestealthiness of the adversary.
