Our new paper shows that terahertz wireless data links 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. This work is a collaboration between our group and researchers at Rice University and at the University at Buffalo.
