Jamming refers to the deletion, corruption or damage of meter measurements that prevents their further usage. This is distinct from adversarial data injection that changes meter readings while preserving their utility in state estimation. This paper presents a generalized attack regime that uses jamming of secure and insecure measurements to greatly expand the scope of common 'hidden' and 'detectable'...
Meter measurements in the power grid are susceptible to manipulation by adversaries that can lead to errors in state estimation. This paper presents a general framework to study attacks on state estimation by adversaries capable of injecting bad-data into measurements and further, of jamming their reception. Through these two techniques, a novel ‘detectable jamming’ attack is designed that changes...
A coordinated cyber-attack on grid meter readings and breaker statuses can lead to incorrect state estimation that can subsequently destabilize the grid. This paper studies cyber-attacks by an adversary that changes breaker statuses on transmission lines to affect the estimation of the grid topology. The adversary, however, is incapable of changing the value of any meter data and can only block recorded...
Undetectable data attacks on the power grid produces errors in the state estimation that can potentially affect electricity prices as well as make the grid vulnerable to failures. A new hidden attack framework is presented for power grids where all meter measurements are secure from injection of malicious data. An adversary here only jams or blocks meter data from being sent to the control center...
