Tohid Shekari - LADIDS: Lightning-Authenticated Distributed Intrusion Detection System for the Power Grid

views comments

Recent events affecting power grids (such as

the Ukrainian blackout in 2015) have highlighted

the vulnerabilities in modern power systems,

especially power substations which form the

backbone of electricity networks. There have

been significant efforts among researchers to

develop effective intrusion detection systems

(IDS) in order to prevent such attacks or reduce

their damaging consequences. However, all of

the existing techniques require some level of

trust from components on the SCADA network;

hence, they are still vulnerable to sophisticated

attacks that would compromise the SCADA

system completely. This research presents a

radio frequency-based distributed IDS which

remains reliable even when the entire SCADA

system is considered untrusted. The developed

air-gapped sensor is also robust against replay/

spoofing attacks, meaning that the attacker is

not able to feed it fake data.
