Researchers have published the demonstration of a fully-integrated single-chip microwave photonics system, combining optical ...

preventing glitches when devices switch between networks, said Kun Woo Cho, a Ph.D. student in Princeton's Department of Computer Science and the lead author of the research. Boosting 5G signals ...

The same nearby attackers can embed data into infrared signals and beam them to an infected camera, where they're intercepted and decoded by the network malware. The covert channel works best when ...

"With appropriate software, compatible radio signals can be produced by a compromised computer ... to other machines on an air-gapped network. Data can be extracted the same way, though this ...

M odern communication networks rely on optical signals to transfer vast amounts of data. But just like a weak radio signal, these optical signals need to be amplified to travel long distances ...
