In this work, we present a novel observer-based masking protocol in order to secure the communication between nodes of a cyber-physical system. The approach is based on including multiplicative disturbances generated from a known autonomous system in the source node and then including an observer in the receiver node that exactly removes the noise and recovers the original signal. It is shown that, if the masking signal is appropriately designed, the de-masking module can be implemented through a simple proportional-integral observer. The approach is then validated through numerical simulations.
