Abstract:
As nation state actors become more active in cyber-attacks on infrastructure, they also become more sophisticated, choosing to target product quality over a plant shutdown, thus making it harder to detect an intrusion. To make cyber-attacks harder to initiate, naturally-occurring polarization in radio frequency signals is being explored as a means of authentication that doesn’t require digital data. By means of polarization mode dispersion, it is possible to protect the wireless channel (the path from sensor to access point) by identifying hostile actors who attempt to imitate authenticated devices to gain entry into a wireless network. In this article, recent test results are examined for their impact on the resilience of this type of wireless security. Specifically, performance in the case of low received-signal-strength is analyzed. Also, troublesome presence of electrical interference from a microwave oven and fans is studied.
