A Stealthy Attack Against Electricity Market Using Independent Component Analysis

In smart grid, the strong coupling between cyber and physical operations makes power systems vulnerable to cyber attacks. In this paper, we investigate a new but serious type of attack, stealthy false data attack. In addition, we demonstrate that the attackers are able to, without prior knowledge of the power grid topology, make inferences through phasor observations. For the attackers to achieve this ability, we show that when the change of …
