Abstract
Abstract. The use of sensors has grown dramatically in recent years and many devices
rely on the information they provide. The lack of proper security mechanisms
available to control the use of sensors and the high degree of integration
make them more vulnerable to Intentional Electromagnetic Interference
(IEMI). The aim of this paper was to investigate the impact of IEMI on
separate sensors with privileged access to the hardware and software to
pursue a deep analysis of the effects of IEMI attacks using pulse modulated
signals. Measurements were carried out in a shielded hall using an open TEM
(Transverse Electromagnetic) waveguide in the 100 MHz–7.5 GHz frequency
range. A variety of effects were observed and significant differences were
found with pulse modulated signals compared to continuous wave signals.
These results indicate weak points in the sensors hardware leading to
possible hardening measures.
