Abstract

The protection of critical infrastructure against electronic and communication network based attacks becomes more and more important. This work investigates the threat of network-based attacks on substations, the nodes of the electric power grid. Three fundamental types of attacks are derived and a secure communication protocol is proposed to counter these attacks by reducing them to a failure mode that can be dealt with similar to other, non-malicious subsystem failures by safety mechanisms.
