It's Canada Day 2018, and some researchers in Canada are not only celebrating their country, but also a breakthrough that could have implications for cybersecurity.
It may give your organization the chance to make data invisible as it travels over fiber optic networks around the globe.
“Our work represents a breakthrough in the quest for invisibility cloaking,” says José Azaña, National Institute of Scientific Research (INRS), Montréal, Canada. “We have made a target object fully invisible to observation under realistic broadband illumination by propagating the illumination wave through the object with no detectable distortion, exactly as if the object and cloak were not present.”
The Optical Society announced the discovery and publication of the research, and elaborated in simpler language what it might mean:
"While the new design would need further development before it could be translated into a Harry Potter-style, wearable invisibility cloak, the demonstrated spectral cloaking device could be useful for a range of security goals. For example, current telecommunication systems use broadband waves as data signals to transfer and process information. Spectral cloaking could be used to selectively determine which operations are applied to a light wave and which are 'made invisible' to it over certain periods of time."
