Abstract

Abstract: Smart electricity meter ( SEM ) is a critical infrastructure of the smart grid. The security problems of SEM are becoming increasingly important. In this research, we develop attack trees to analyse the attack paths that a cyber-attacker might follow to attack the local metering system consisting of several SEM s and a data concentration unit. Then we use game theory to model the interactions between an attacker and a defender. For the former, he/she expects that the attacks can be realized with high probabilities and profits. The purpose of the research is to help the latter to realize the optimal allocation of limited defensive resources.
