Session Abstract
This tutorial will present the threats posed by intentional EM interference in the field of information systems security.
After an introduction and a brief history of passed works on IEMIs, the main characteristics of the IEMIs that can be employed against communication systems will be presented.
This will be followed by an introduction to cybersecurity exploitation of IEMI, providing an overview of how IEMI can be used by attackers and the outcomes on the security of information processed by electronic equipment. Several threat models will be explained and illustrated by a literature review or insights on original research.
The rest of the tutorial will focus on the use case of Wi-Fi communications in the presence of radio jammers.
First, the audience will be reminded of some preliminary information on the Wi-Fi protocol and OFDM modulation.
Then, the mechanisms by which this IEMI affects the Wi-Fi communication protocol and OFDM modulation will be presented in detail. The different impacts will also be discussed and an experiment will be carried out live in the room to illustrate how the source of IEMI affects the communication quality, depending on the position of the IEMI source and the waveform of the IEMI signal.
Finally, the rest of the tutorial will present work that has been carried out to detect and geolocate these sources of interference inside a building.
