Study exposes security vulnerabilities in terahertz data links
(PHYSorg.com Physics)

A new study shows that terahertz data links, which may play a role in ultra-high-speed wireless data networks of the future, aren`t as immune to eavesdropping as many researchers have assumed. The research, published in the journal Nature, shows that it is possible for a clever eavesdropper to intercept a signal from a terahertz transmitter without the intrusion being detected at the receiver.
