Abstract

This paper presents a watermarking signal injection method that compensates its effect in the loop, avoiding thus the signal reinjection. Similar to a virtual actuator scheme, the proposed methodology masks the presence of the authentication signal to the system controller, that do not need to be retuned as it remains immunized. Furthermore, a set-based analysis concerning the effect that the performance loss imposed by a watermarking signal has in the detectability of a replay attack is performed for the stationary, assuming that a standard state observer is used in order to monitor the plant. Finally, a numerical application example is used to illustrate the proposed approach.
