Detecting cyber attacks from untrusted components in smart electricity substations

الملخص

Modern power grids have been experiencing a digitisation process in recent decades. Particularly, substation automation systems which monitor and protect the physical processes of electricity substations, have been developing with more intelligence. However, the advancement of "smart" substation automation systems not only brings convenience to the control process but also introduces new security issues. Motivated by a common concern from the energy industry about the dangers posed by untrusted third-party components, our research focuses on protecting a substation from untrusted devices which have been installed inside its security perimeter.
